💬 Easy/Newbie PCB for MySensors
-
Hello @sundberg84, I would like to buy the Easy/Newbie PCB for MySensors but I have a few questions
I want to use it the 5V Arduino Pro mini not the 3V version
I also want to use the battery monitor
Is it ok or should I modify "something"
Also all the pcbs have the battery "expansion: or not?
Thanks, Emmanuel
-
Why would you want to use the 5v arduino on batteries?
-
I want to use it the 5V Arduino Pro mini not the 3V version
Then you need to use the nrf24l01+ version, that works fine - the RFM69 version needs a 3.3v Pro Mini only.
I also want to use the battery monitor
As @gohan said - don't use batteries on a 5v node. Use a 3.3v because it will use up your batteries very quickly. See the guides i have on openhardware for different modes on my PCB.
Is it ok or should I modify "something"
Also all the pcbs have the battery "expansion: or not?"something" is hard to understand, you can modify i many different ways depending on what you want to do. All the basic "modifications" can be found if you read the project page on openhardware.io
-
@sundberg84 thanks for your response
If I don't care about battery consumption can I still view and use the battery monitor to be alarmed when battery is empty?
-
@manos yes you can.

Hello @sundberg84. I watched your video 9+ 'MySensors Battery Node 2xAA - EasyPCB (Nrf24l01+)and Temp Sensor' . I have two questions about this video:
- I noticed you connected the tempsensor to the extra prototype part of the board, but i could not see in the video how you connected signal pin of the sensor to the arduino.
- you added a resistor to D5 Temp/Hum, but you did not add the sensor to the mysX2.4 part of the board. Why is that?

Easy/Newbie PCB for MySensors:Hello @sundberg84. I watched your video 9+ 'MySensors Battery Node 2xAA - EasyPCB (Nrf24l01+)and Temp Sensor' . I have two questions about this video:

- you added a resistor to D5 Temp/Hum, but you did not add the sensor to the mysX2.4 part of the board. Why is that?
I connect it on the back with a normal wire to D5 resistor input. So both of your observations above are correct.
-
@sundberg84 yes i thought so, but i want to make sure. I have some Rev 10 boards and i was working on a node for my bathroom with a DHT11 sensor. I had some problems with it, therefore watching your video. But it looks like the step up booster was not working correctly. Unfortunately removing the booster i damaged the board because with a new booster the arduino won't get power any more. So this board only works without the booster (and reg jumper connected). Any idea how long this setup (with removed led on arduino) will last on batteries?
-
@mister_ik - well, 2-4 weeks more or less unless you reprogram the fuses and bootloader.
-
@sundberg84 ooh that is not very long ..i hoped for a couple of months....but then I should consider this board as depreciated and build a new one and use this for development. Thanks for your reaction.
-
@mister_ik you can always use wired to repair the damaged tracks.
-
@sundberg84, thanks so much for this board, I bought 10 of them. This has made my sensor projects much easier and they look better too! I think I will get some of the RFM69 version next.
I have a lot of gel lead acid batteries (the 7.2AH type often used in UPSs), and I have been running an earlier prototype off that. I have now just changed over to your board and this is how I modified it to work the way I wanted:
- Cut the track circled
- Hard wired from the regulator side of the battery jumper to VCC on the Pro Mini
- Bridged the booster In to Out
- Changed the battery measuring resistors to 12k/180k for greater range
This enabled me to run the board off 12V, keep an eye on the battery voltage, and run the rest from the LE33 regulator. It seems to be managing so far, with 3 x DS18B20 temperature sensors. I'm monitoring the fridge outside, inside and freezer temperatures with this module.

@ajay100 - Hi!
Really nice to see you found your way of using my PCB, its just the way I want it
I tried to follow along here, are you using the LEd33 to convert 12v to 3.3v? I guess you tried RAW and the voltage regulator on your pro mini and found out it was bad due to cheap clones?If you cut the trace just above the volt.reg and put a jumper from REG to Vin on the Volt reg, and added a jumper from Bat (top) to Reg (top) you would also feed everything with whatever comes out from the LE33.
(I think)
-
@sundberg84, I've just tried it and that is a better solution than mine for running everything from the LE33. Thanks for taking the time to work that out!
Cheers - Andrew
-
Hey @sundberg84 I just saw the new rev.10, congratulations on the upgrade!
I still have a bunch of rev 9, do you happen to have images/manual for previous version somewhere? link or a pdf?
Thanks!
-
@dakipro - sorry, everything was saved here on oh.
Is there something special you need? I can maybe send it to you, like schematics or what are you looking for?
-
Zip files with old revisions get stored on openhardware.io but is not exposed in any good way for the end user today. They're only accessible for the manufacturers.
I will see if I can show it somehow. Maybe a new tab on the project page listing old revisions with download links.
-
Ok, revisions now available. E.g:
https://www.openhardware.io/view/4/EasyNewbie-PCB-for-MySensors#tabs-revisions
-
Thank you @hek , I think this might be useful feature
I however do not see any data in there, is it something for project owner to allow?
I tried both as guest and as logged inn, I do see the rows, but no data in fields, screenshot:
@sundberg84 nothing special about now, I figured it out based on older projects. But since I still have about dosen of boards, I will probably need documentation few years from now, so was just hoping to have it somewhere easily available
Like a downloaded pdf or something
-
Thanks for reporting @dakipro. It seems to have been a caching issue in the service. Should not appear again.
-
Me too i still have a bunch of rev 9. Where can i have all the old informations for this rev? I need to see the old webpage with instructions. Thank you !
-
Thanks @hek it is certainly helpful. However the most powerful information is actually in the description page, about how to use the board, how to wire it up for different use cases etc. I suppose a previous version of the information tab is not available?
If it could be archived (maybe even linked somewhere) it would be really helpful!
-
The documentation at the time of the created revision is actually included in the zip as README.md (markdown).
You should be able to view the file properly formatted in an md-editor or online using I.e.. https://dillinger.io/Uploaded images was never included in the revision dumps unfortunately.
-
Ooops, my bad then
I was pretty sure I checked readme.md file, but apparently I got confused.
Thanks a million!
-
I am also looking for documentation for Rev. 9 that I purchased. The link with revisions that was provided: https://www.openhardware.io/view/4/EasyNewbie-PCB-for-MySensors#tabs-revisions
lists revisions 1-7, but not 9. All I need is readable schematic and PCB layout in PDF. Thanks.
-
@apl2017 I don't know where the revision numbering comes from, but I believe the rev9 you are talking about is called rev5 on the revisions tab.
Rev 10 was created 2018-06-04. That date matches with rev6 on the revisions tab.
Perhaps @sundberg84 knows why there are two sets of revision numbers?
-
What software was used to develop this board? My latest KiCad does not read schematic from Rev. 5 ZIP file. All I need is a simple PDF...
-
@apl2017 - Rev 10 = Kicad, but all below is Eagles.
This is Rev 9, Nrf24l01+
@mfalkvidd - the rev tab in openhardware is the revision for the manufacturer. This doesnt match, because it starts at 0 and ticks up. If you have a board with rev 1 but make a small change without updating the revision number but still wants to upgrade it to the pcb manufacturer you need a new revision for them... so thats causes the confusion. But i think @hek named it M.Rev (Manufacturer revision) to try to keep them apart.
-
Sorry to bother you again (3rd time), still waiting for readable PDF of Rev. 9 schematic and board layout. Thank you
-
@apl2017 - why pdf? The image above is just as good? It wont present any other info?
The reason why I ask is that I dont have eagles installed anymore... so its a bit of hassle for me.
-
sundberg84 Don't bother, I went through the hassle, downloaded Eagle and created readable PDF
-
@apl2017 care to share?
-
Hey, @sundberg84 , I am trying to order the rfm69 version from ITEAD and their M.Rev1 file I downloaded looks to be your v9. Can you upload the v10 to them so I may place an order?
-
Hello, i have built my first sensor based on your PCB. I am of course in learning mode so it refuses to work so far. it is motion detector. I suspect a problem on the radio nrf24 but does not know how to monitor the node with Arduino IDE serial monitor. If i connect the board to the USB the radio is not powered (built the node on battery). and if i connect the battery i have no access to serial monitor. I am afraid to connect both the USB and the batteries and burn the all thing...
so far i know radio receives power/ PIR receives 3.3 Volts (have configured the PIR to 3.3)/ arduino mini pro led comes on with battery connected.
Any advice would be really welcome.
-
The radio is only powered by the battery, the battery must be connected to test. Connect both the usb (set to 3.3v) and the battery, no damage will be caused by this.
-
Thanks Stephen. connected both and i can now see what is going on
-
@ElCheekytico - I dont know why they wont update to rev 10. I have uploaded the new revision to openhardware... nothing else I can do, sorry.
-
@pierre1410 - I would suggest you connect the battery, and then the usb/ftdi cable, but only GND, TX and RX fro the usb connection. This will have the node running on the batteries VCC and get you closer to the real deal. Using VCC from the usb adapter might be higher VCC than the batteries, and in worst case scenario it works great with that connected but not when you deploy and only use battery power.
-
@sundberg84 that is exactly what i experienced. thanks for the tip. struggling in fact to have my PIR sensor running on 3.3V. when i connect to the pin on the right of the board (3rd from top).. Arduino IDE serial terminal does not outcome any coherent information.
-
@pierre1410 ok - well not to get your hopes down but a motion detector on batteries are one of the harder builds. If you are using a booster with the batteries it's harder due to false triggers from the booster noice. Also I believe the quality of your motion detector module determine if it's possible..I've had detectors running fine on 3.3v but several which didn't.
-
Hello, Is there a way to solder a DC-DC booster 3.3V to 5V directly onto the Easy PCB or should it be connected separately to power a PIR for instance? and would that really prevent using 2xAA batteries to power the all thing? have tried to step down the PIR to work at 3.3V but it was not conclusive. Thanks a lot.
-
@pierre1410 - you can always use the prototyping area for a 3.3 to 5v booster but... booster + PIR might cause false triggers, so choose your booster wisely.
-
@sundberg84, had to migrate my gateway to Ethernet in the meantime but now I am on the PIR/ battery case. i have my booster to 5V in.. will post the results of it...
-
@pierre1410 why do you need 5v? There are pir sensors working at 3v and you can even modify the standard pir sensor to work at 3v
-
Hello
I think there is a mistake in your code (on github) to mesure battery.
The array have 4 values, but you divide by 3. So you get to high result.
https://github.com/sundberg84/HomeAutomation/blob/master/BatteryMeasurer/BatteryMeasurer.ino
On line 77Everything else is ok in my case
the board works well with 2 battery AA, and 47uF cap (not with 4.7uF) .
-
Nice catch @barrydou
The bat array is declared to hold 3 elements
int batArray[3];but then 4 values are fetched
batteryPcnt = (batArray[0] + batArray[1] + batArray[2] + batArray[3]);batArray[3] is outside of the array, so the ram here could hold any value.
The code should probably be changed to this
batteryPcnt = (batArray[0] + batArray[1] + batArray[2]);
-
@mfalkvidd : I think you have to change the condition in if too :
if (batLoop > 1) {With that, batLoop = 2 when entering in the if (so the 3 values of the array are filled : 0, 1, 2), calculating the average and reseting the batLoop to 0.
If not modify, the array will be set with batArray[3] just before entering theif (batLoop > 2) {Other way is to set the batArray size to 4 values, and divide by 4 (I'm actually trying that).
-
@barrydou @mfalkvidd - thanks.
Wouldnt it be easiest to just "+ batArray[3]" so it isbatteryPcnt = (batArray[0] + batArray[1] + batArray[2]the declaration = 3 elements
batterypct = 3 elements
batloop > 2 should be correct (0,1 and 2)I dont think the code has made any faulty readings since the declaration is only for 3 elements, making batArray[3] never used? (Or always been 0). The batteryPcnt is then divived by 3.
-
@sundberg84 batloop > 2 is incorrect, since that means batloop==3 and the code above has just written outside the array, corrupting whatever happened to be there.

We must be ordering EasyPCB alof from PCBway since they used it as an example board for this youtuber:

@sundberg84 haha gorgeous, I think they only sent open hardware boards, and ran some batches from boards available on openhardware, as except the perfboards they send as free gifts the other real PCBs are MySWeMosIRShield by @emc2 and the RollerShutterNode by @Scalz

hello, i have a stupid question... on the 3 rows below VCC and GD on your prototyping area; are the rows connected horizontally like a breadboard? thanks
-
@pierre1410 - no stupid questions, simple answer though, no

Hello Sundberg84 et al,
I purchased Easy Newbie PCB (Rev 10) with the hope of jumping into the IoT rave... I tried to create the Gateway - and it works perfectly. I also found and created an advanced Water Sprinkler MyS project by Pete and Co!... that also worked perfectly.However, I cant seem to get simpler beginner sketches to work with EasyNewbie. I have soldered the need components (the regulated version). I plan to connect to a 4 relay module, but for now, I am simulating the relay with a simple LED attached to D2. I have uploaded the following sketch which was originally written for version 1.0 MySensors - but have been corrected using guidelines I found for converting 1.0 - 2.0 version. but still no cheese - the controller (Domoticz) displays the Node, but not the complete child nodes, - the LED connected to pin D2 (or D3, D5..) on the Easy Newbie doesn't light up even when I toggle the switches and devices on controller. Don't know what I might be doing wrong, please help.

@eme - hi!
Im very sorry, code is not my strong side.
Do you think its a problem with the hardware?
Do you have any logs?
-
@sundberg84 I have the Domoticz log below. but just incase it doesn't reveal much, do you have a working sketch for EasyNewbie and a 4-relay module block?

-
@eme sorry I don't. The most common "issue" is that power is to weak for 4 relays or noice is introduced in the radio from the relay.
It's very hard to understand without real logs. Sorry
-
I eventually got it to work. I am not using the EasyNewbie to power the load (its for 24volts swimming pool light). Couldn't get the 4th relay to work - not sure why its not responding to the controller. but I noticed some bug with my batch of 16 PCB -
Okay I think I have seen some bugs... my batch of EasyNewbie Rev 10 has some hardware issues - The provisions to attach sensors are not correctly marked. D6 doesn't actually connect to D6 pin on the Arduino (must have failed a via somewhere). I am not sure how many pins are used for the radio and other components, but if you intend to use this for a small project, I will avoid D8 - D13 as they appears to be taken. D1 and D2 are used for the TX & RX so you only have D2 - D6 to play with (more than enough pins for a newbie if you ask me).
-
@eme good you found the issue. First time I ever hear of a comfirmed PCB hardware bug, so its very rare. Very strange the silkscreen were moved or not aligned correctly as well. From where did you order the PCB?
The documentation states which pins connect to what on the PCB, so make sure you check that out. D9-D13 are used by the radio as in all MySensors projects. D8 for the extra flash. You can find the MysX documentation here as well if you need to find out more about the pins.
-
@Sunberg84 I bought them off Ebay via this very site... The Packing List reads Shipped by Abdera's Sundberg Ostra Gransgatan 2, Lonsboda, Sverige 28070, SE. I believe that's you.
Well I am forced to solder directly to the Nano pins, and so far so good. I think you should help with a 4 relay sketch that works. My appears to be a hit and run, works in the morning and fails after a while. but I am learning as I go.
-
@eme Thats me - ok, good to know then - but I guess you mean the Mini pins and not Nano since the PCB doesnt support the Nano?
-
@sundberg84 Yes you are right I meant to say ProMini not Nano - I have 18 of these PCB - not so happy I have to solder directly to the Arduino - that's exactly what I was avoiding in the first place. Do you have a good relay block sketch that works? Much appreciated if you can help.
One last thing, I am trying to run a node off a 12Volts battery, can you explain this image below again?
- Will this work for a 5V Promini?
- What are the blue lines? and
- what are the red lines?
-
@eme - its is very strange - I have a big batch here with Rev 10 and i checked atleast 20 of them randomly and all have continutiy between D6/pro mini and D6/MysX. You must have had extreme bad luck and if you check the others it should be ok.
Can you post a picture (close up) of the board not working please showing D6/Pro mini and D6/MysX.
For 12v I would use the prototyping area with a 12 > 5v converter. If you want to use the internal voltage regulator on the pro mini you can connect to RAW but beware that clones will not handle this very good. The specs are 12v but I have seen many bad clones getting destroyed.
I dont really remember this image and from which context this is from. I guess the lines represent different voltages. Adding 12V on reg and a 12>5v regulator on the TO92 footprint will convert and feed the board 5v, but kill the radio...
-
I just checked my batch of Rev 10, random check of the batch checked out OK. I have 20 boards.
-
Dear sundberg84, thanks to your really nice and easy mysensors PCB. I ordered ten of them via SEEED and they were delivered today (REV.10). Unfortunally I found some serious bugs in the PCB design regarding the SPI Flash: First pin 6 (SPI SCK) of the flash chip is not connected at all - should be digital IO pin 13 of the Arduino pro mini. Second mistake: the filter capacitor of the flash chip is not between VCC and GND. Third mistake: pin 3 and pin 7 should be connected to VCC and not to the filter capacitor. I changed that on my arrived boards and the flash chip is now working perfectly. Kind regards, JPM
-
I checked the schematic, and:
First mistake: Seems that the schematic is OK, the label for SCK (pin 6) is connected to physical pin 16 which is PCINT13 on the Arduino,
Second mistake: that is a bug, filter capacitor is not connected correctly.
Third mistake: That is also a bug, pin 7 and 3 should be connected to VCC
Now I am going to check the PCB, be back shortly,
-
I have now checked the PCB, and you are right @JPM
Pin 6 of the flash chip is not connected at all. No wonder I could not get that to work. Strangely is that the schematic is OK.
Thanks for finding this, I will modify my boards to get them working.
-
Sorry for this. The flash has been untested by me. I will fix this asap and upload new files.
The schematics is wrong:
New schematics:
The same error goes for RFM version
-
@mickecarlsson I found this out and wrote it above that D6 is not connected at all... but it was promptly swept aside cos nobody had reported it before now. I am glad someone else saw it, and that you had the notion to check. D4 is also not connected to the test area. I have been connecting directly to the Nano.
-
@eme im sorry - since your wrote "The provisions to attach sensors are not correctly marked. D6 doesn't actually connect to D6 pin on the Arduino" I thought you was talking about the MysX connector and not flash. If you mentioned flash I would probably found the issue. They are not talking about D6 but pin 6 on flash which connects to D13 on the Arduino.
Are you sure it's the same problem? Not much that sounds the same.
-
@sundberg84 if you look at the schematic you have connected MySX pin 10 to D2, but according to the spec for the MySX 2.4 it should go to D4.
-
@mickecarlsson - I understand your point, and I have changed this back and forth and also asked @Anticimex becuase its a but unclear in the documentation.
MysX 9 + 10 should go to a Digital IO with interrupt, and D2 and D3 is the only pins with interrupts on mini.
I guess you are refering to Mysx_D3_INT but this is the MysX name.
-

It is important to remember that MYSX is agnostic from any devices.
Any names in MYSX pins bear no correlation to any device specific pin naming, so D3 and D4 mentioned on pin 9 and 10 has nothing to to with any D3 or D4 on any MCU.
If you look here, you will find that the 'A' and 'D' notation is simply an indicator of the pin function (analog or digital) and it simply increments with the pin number, so the lowest analog or digital pin number in the MYSX connector will start at '1' and then increment as the pin number increments with '2' for the next digital being on pin '6'.
Also note that since some pins are deprecated in MYSX 2.x, MYSX 2.x analog pins starts with 'A3'.

I was wondering if there are any CAD files for corner through hole size/locations for Rev 10? Trying to design enclosure for it.
-
@birinderk SHould be easy enough to measure it with a caliper. That's what I did with the earlier revisions of the board (rev 8 & 9). They had pretty much the same hole spacing. Here are a few of the enclosures/sensor cases that I did that fit the rev 8 and 9's.

Does anyone know where we can find the write ups for old revisions? i have a bunch of Rev9 boards that, now that i have restarted these projects after a year break i cant remember the write ups for them....
-
@markjgabb do you mean the stuff in README.md in the zip file that can be downloaded on the revisions tab?
-
@mfalkvidd yeh i guess so, not quite what i was after the orignal in that version had some good pictures and such of what went where on the board....do doubt i can work it out from an old dead one i have lying around, was just hoping for a nice visual guide to get me back into it.
-
@markjgabb not sure if this is what you want, but if I paste the contents of the readme into a markdown viewer (for example https://dillinger.io/ ) I get the images:
-
@mfalkvidd ahhhhh That answers my question perfectly....i was just dumping it into notepad ++ ill try that first thing in the morning.

Hi,
First of all: I really appreciate the simplicity and flexibility of this board!
Now then, I have a problem with battery life which is only around 3 weeks for my DHT22 node and around 8 weeks for my BMP280 node. Both are 3.3V mini clones with NRF24 radios (probably clones) that run on 2xAAA batteries and a booster. I use NodeManager for software and report sensor values in 2 minute intervals. LED and voltage regulator has been desoldered from the Pro Mini.
Why isn't battery life better - am I missing anything obvious?
-
Can/should I remove C2 (10uF) and C3 (0.1uF) capacitors? I added them first but after checking the schematics I now think they are not used at all for the battery/booster setup?
-
What battery life can I expect for a BMP280 on 2xAAA batteries and booster?
-
New batteries report at 3.13V. When the nodes fail, reported battery voltage is around 2.6V. However, when measured I get it to around 1.6V (at no load). This could be a software problem but I include it as a clue. My setup in NodeManager is:
battery.setBatteryPin(0); battery.setMinVoltage(1.8); battery.setMaxVoltage(3.1);

@fredswed - Hi!
You should be able to get much longer batterylife than this! I have same setup running around 12 months.It is hard to say, your setup in the image looks correct. Sometimes when i bought boosters or sensors they draw much more current than expected due to clones. In these cases I try to solder pro-mini and radio, then connect a multimeter in series with the batteries to analyze current consumption - then add sensor by sensor to find out what is drawing current - is this possible for you?
- The are used for the booster to smooth noice, so both can be used in your setup.
- 2xAA with DHT22 = 1 year, BMP280 has a low current consuption when sleeping so it should be able to do atleat 1 year there as well.
- I dont know nodemanager. The booster should boost the voltate for VCC, so it depends on the specs for your booster.
My first thought is that your BMP module is always active drawing alot of current even though you put the node to sleep. Test current consumption during sleep. Should be < 100uA and even maybe 50 uA atleast!
-
@fredswed hello, are you sure you booster is wired correctly and running fine ?
Node failing around 2.6V looks a lot like the value before the default brownout detection (2.7V). Then when you are at this level the node will be in a reset loop forever and completely drain the battery, but of course your node will not be able to report it.
So I would check the wiring and behavior of the boosters as they don't seem to do their jobs. I might be wrong but it would be a strange coincidence to have both nodes failing just at the brown out voltage.
-
Hi A question about powering using the step booster. When I connect the BAT jumper it would seem from the schematic that the output of the booster will be delivered to vcc (i.e. the arduino) but the supply to the radio module will be the battery supply. Is that what was intended?
-
@4994james yes. The radio supports lower voltage, and is extremely sensitive to imperfections in the power supply voltage. The booster introduces a lot of imperfections.

Excited to get started with this board, ordered 10 and soldered up the basic components for a 3.3v battery-powered sensor last night. Got everything soldered exactly as in the battery operated picture for rev 10 on the newbie-pcb page with the exception of the D5 resistor.
When I connect the batteries to the PCB, the LED on the pro mini does not turn on, so I'm assuming it's not getting power. When I connect the battery to RAW, the LED on the pro mini turns on. Any ideas on where I should start troubleshooting before I start removing and replacing components?
I know the pro mini is good, I've uploaded a sketch to it using FTDI. I'm pretty sure my soldered connections are ok. I've double checked caps and resistors. I don't think I checked the step-up booster, so I'll try to test that to ensure it's functioning correctly, but any advice would be really appreciated!
-
@genuinejd - can you post a picture of your pcb? Might be easier.
If you have a multimeter, you can measure the input and output of the booster.
-
@sundberg84 I meant to post a picture, then last night I discovered my issue. I soldered all the components except the pro mini! Once I did that, everything started working. I did discover that mys was reporting "No potential parents replied to find parent request." Once I changed my radio cap from 4.7 to 47 it started sending messages immediately.
Here's my first node (I haven't removed components from the pro mini yet for extended battery life), with bare minimum components in all it's battery-powered newbie glory!
Thanks!
-
@genuinejd - Nice work! Thanks for reporting back!
-
@sundberg84 So as it turns out, it worked great for about a day while I was letting it run to test battery life. Suddenly my gateway was not receiving any messages from my node.
- I checked all the caps, the booster, etc.
- I tried a few different caps for the radio up to 100uF
- The voltage on the radio matched the voltage from the battery.
- I tried switching to the REG jumper and wiring across the voltage regulator, the radio was then getting 3.3v from the booster, but still no communication between the node and gateway
- I also tried using my bench power supply for reg 3.3v.
Strangely, the ONLY thing that worked was when I used the 5v post on my bench power supply (with the BAT jumper, no voltage converter)
I have not yet tried swapping out the radio since it works with 5v, but I'm unsure what to try next. I have 6 other mys nodes communicating with my gateway with no problems and greater distances (all using nanos).
Any suggestions? Apologies if this doesn't sound like an issue with the board, I can post in the troubleshooting forum if you think it's a radio problem.
-
@genuinejd - the radio can not work with 5v, sorry but this might destroyed your radio. Do you have any serial debut for your node? Can you see what it does? It might be alot of different things, maybe the booster. In many times I have seen bad boosters which introduces noice and makes the radio go crasy.
-
@sundberg84 I know that everything I've read says the radio cannot use 5v, but when hooked up to my bench power supply and connecting my multimeter leads to the NRF24L01+, it says it's getting 5v AND it's the only scenario where the node can successfully find the gateway and send/receive data.
I tried swapping out the radio and it was the exact same scenario. I'm getting NACK debugging messages on the gateway when it's trying to accept the node as a child. The only thing I haven't tried is replacing the booster.
For the moment, I wired up a second node with all new components and (after remembering to solder everything) it connected to the gateway right away. It's been running for about 30 minutes, so I'll post back after a time when I know if it will stop working or run until the batteries drain completely.
Side note: thanks for making such an awesome board!

Hi,
I build a node using an easypcb rev 10 for the rfm69. I am trying to connect two door sensors to the node using pins 2 and 3. The sensor on pin 3 works flawlessly, but the one on 2 doesn't (I'd like to use the interrupts to save power).
I saw that the Nrf24l01+ version has disabled pin 2, is that the case with the rfm69 version too? If yes, is there any way to use two different pins for interrupts? I need to know which sensor has been triggered so I can't connect them in series.
Thanks for the help!

Is there a .sch version of the schematic that I can import into Diptrace? I can only find a .pdf
-
@kiesel sorry for the late reply. Did you solve it ?
-
@Woodside all files should be posted @ openhsrdware.io. Is this some special file?
