@Abdu-Sahin I was interested in reading your conversation about battery life etc. I hope you will continue the conversation on the forum instead of in private.
Thanks.

It is possible to buy only PCB ? Upload PCB to OSH Park, or send PCB in eagle. I do not have Altium Designer... Thx
-
@Miroslav-KadanÄ› I've just uploaded latest gerbers (rfm reset pin was connected to controller, connection of si1132 was fixed, reverse battery polarity protection was added). You can place PCB order at any factory.
-
Maybe a stupid question but how do you connect the FTDI adapter? I only know the ISP pins
-
Few months ago, I've ordered some of your nodes, which work perfectly by the way, but I needed something that could speed up testing of any sensors.
So following our conversation on Github with Yury, I've created a PCB based on your Button size node, with a field for an extension board. The aim is to have a versatile board, and extensions that could handle virtually any sensors, like NodeManager project, but for hardware
And it's also a first time experiment in the land of PCBs
Apart 2 errors ( maybe more in the future !), it seems to be well routed, as tests been proving, but i still not tried the FOTA function.
Errors was a badly routed button and it seems that, after the RFM chip is soldered, communication with USBasp gets bad! Is it because SCK and MISO route ( from pin headers to atmega328 ) goes through the RFM chip before atmega ?You were mentioning some mods in dualoptiboot in order to flash M25P40, https://forum.mysensors.org/topic/3160/ota-flash-types-for-mysensors/43.
Would it be possible to share these ?And just out of curiosity, how did you manage to solder SI7021 and TSL2561 ?
By now, it seems like a mystery for me...

Button size radionode with sensors swarm extension:after the RFM chip is soldered, communication with USBasp gets bad
Did you solder R4 (from your schematic https://github.com/getlarge/Cosmonode/blob/master/Cosmonode_sch.pdf)? I can't find it on the boards photo.
PS
Will share compiled bootloader and sources soon.

@Koresh said in
Button size radionode with sensors swarm extension:Sorry, picture's quality is not too good!
R4 ( 10Kohm) is soldered. I read about that pullup resistor that is needed to sync with atmega SCK. Any other hint on what could cause that ?
Maybe, that was a mistake when i changed the fuse? but I didn't have problem before with these settings.So I'll have to be patient to use M25P40!

Can anyone quickly tell me how to do it correctly? I thought it didn't work but I'm unsure.
-
@chbla This board has standard FTDI header (see attached screenshot).
But it also has all of ISP pins (mosi, miso, sck, rst)
-
@Koresh Might be a dumb question I am planning to work on this board, where do I find the complete part list.
-
Does any one have links to dirty pcb or OSH Park? Thanks a lot

@Miroslav-KadanÄ› Thanks!!

I do not have an electronics background. I wend through the pdf files and order the parts and looks like I got the wrong resistor and capacitor or wrong part. Looks like I have to wait for an expert to comment let me know which resistor/capacitor goes where what part size. I would love to hear from someone

Re:
Button size radionode with sensors swarm extension2 cr2032 winter upgrade - works nice
Keep working at -20 Celsius in a fridge. voltage dropped from 6 Volts to 5V and keeps pretty stable while sending temperature reading every 2 minutes for 2 days now.
-
There are so many reasons to use two CR2032 batteries in series with power converter instead of one lager battery like 2450
-CR2032 are much more widespread batteries
-Wider temperature range
-Stable voltage during all battery lifetime (using voltage converter)
-Stable radio power during battery lifetime
-Batteries give less current during transmitting so they are not "shocked" by high current.So I plan to create version with two CR2032 batteries holder (like on the Yury's photo) and the ultra high efficiency DC-DC converter based on the tps62745 (400 nA quiescent current, 90% efficiency)
-
The main problem is finding a button holder that can hold two CR2032's in series. So far I've only found two. One is made by Linx, but it's definitely not ideal:
The other works fine, but it has a larger footprint, so I'm not presently using it. It may work well on your board, though, because your board is square, so you can use the diagonal:
On the other hand, maybe you could bend down the tabs and use it as a through-hole?
I did one where I simply cut-off the tabs and then soldered it to the board. That works, but it leaves me with an uneasy feeling as to how long it might last in that configuration. Maybe it's worth re-visiting.

@koresh Hello,
can you please update pcbdoc and schdoc files ?
And add a pcb adapter from RFM69HCW to RFM69CW ?
Thx Mirek
-
@miroslav-kadanÄ›
Hello Mirek. All source files are actual, I used exactly the same files to produce latest stable version. I never share source files until I test the board. So I will share updated files (like on the latest screenshot or better) after the board will be checked and tested
PS
I've added rfm converter board.
-
With the default sensor and sketch I only get integer values - shouldn't this be decimals with 2 digits after the . ?
Not sure if I have a different lib or missed something
-

What's the typical time you get with the default node, coin cell and the sketch on github?
https://gist.github.com/solars/6116b78ea7ee581ecfafddb8da4a9610It drained within only 1 day for me
-
is it sleeping 5 seconds only?
-
@gohan said in
Button size radionode with sensors swarm extension:is it sleeping 5 seconds only?
You are right, that was my mistake after testing it. However, the consumption still seems high.
For example I'm right now testing a BME280 which I want to use in the future, with the following sketch:
https://gist.github.com/solars/a5302f1cb60d90f89d7e37d5e23f8c4dIt's connected to SDA/SCL and GND/V - somehow the voltage it receives with a fresh battery is already quite low, and it also doesn't last very long.
-
you need to try to measure current while the sensor is sleeping as it should be a few uA maximum
-
@gohan I only have a normal multimeter - what's the best way to do this?
I came across https://www.eevblog.com/projects/ucurrent/ a while ago, is it worth it?
-
There is a project in openhardware for a current meter if you want to build one, or you could buy a newer multimeter if the one you have can not measure uA
-
@chbla said in
Button size radionode with sensors swarm extension:multimeter
You should be fine even with a cheap multi-meter as long as it has uA scale.
should be around 7-10 uA and if you do not send JDEC to sleep it is 17 -19 uA.
to send JDEC to sleep\wakeup I use
_flash.wakeup();
_flash.sleep();light sensor should be sent to sleep explicitly also.
-
@yury not really, I have bought an Aneng cheap multimeter, but if I connect it with uA scale selected it will go out of range during node boot and cut the circuit making measurement impossible (unless you do something fancy that would make it unpractical)
-
@gohan said in
Button size radionode with sensors swarm extension:selected it will go out of range during node boot and cut the circuit making measurement impossible
my cheap one survives 20mA surge (RFM69 CW version) of initial communications and displays good reading afterwards. if you burned fuse inside, try replacing it temporarily with some thin wire for this uA tests.
-
I have another cheap one that works. I didn't blow the fuse since turning it off and on it works again, it must be a software limitation

@Koresh would it be possible to sell this without the sensor part and RFM69? How many orders would it need?
I don't have the possibility to produce it myself, don't need the sensors part and have a lot of RFM69s lying around..Thank you,
Christoph

I downloaded gerber files.
Error Message from PCB Manufacturer:
The NC drill layer does not match with the pads of copper layer.Thank you,

-
@anovak
Hello. Do you mean main board or rfm69 adapter? It is very strange. I produced exactly these gerbers many time.
-
Finally I have a little time to continue this project...
High efficient dc-dc converter works nice and double cr2032 are good. Lets go to the furher tests!
-
Thanks. The problem was solved.
Manufactured at very low cost on pcbway, they are manufactured with "Min Track / Spacing: 5 / 5mil".
Do you have any idea where they are manufactured cheaper?
-
New version with double battery holder and power convertor works nice.
Power consumption in sleep mode is less than 9uA
I will test it soon..
-
@koresh You only have two sensors BH1750 and Si7021. Did you try to have all four sensors and measure consumption?
-
Which pcb manufacturer do you recommend?
I asked for a quote from Pcbway but it was expensive.
The reason was:
Change the 'Min Track / Spacing' value from 6 / 6mil to 5 / 5mil.Sorry for my bad English.
-
@anovak Unfortunately you can reduce the price of the board only if you order more boards.
-
What price can be made in 10 items?
-
@anovak if you mean 10K maybe you can have a discount
-
10 would be needed for the current project
At pcbway, the total cost of production and shipping costs is $ 34.
Is there someone who does it at a lower price?
Business account required.I apologize for asking this question in this topic.
What type of transformer do you use and where to get it for the Mini Relay Box?
-
@anovak do you want them completely assembled?
Yesterday I ordered 2 plain PCB's from seeedstudios, cost me 20 dollars incl, shipping. paid more for shipping than for the PCB's themselves.
but for the size, these units are you can get 6 or more in one design.
-
Only PCBs are needed.
-
@anovak I use in mini relay box the same transormer as in wall switch insertable node. Please read this comment https://forum.mysensors.org/topic/3938/wall-socket-insertable-node/57
-
Can we buy it fully assembled and what would it cost?
-
@kenci
Yes, in a week or so. Even with plastic enclosure ))
-
@yury what would the price be for the fully assembled board?
-
@kenci
EUR 18 the board with SI7021 and BH1750. extra 1EUR for enclosure if someone need it.
-
Please link for enclosure

No, no need to connect RST with GND.
DTR works automatically - as soon as you press upload in your Arduino IDE, it starts uploading the sketch to the atmega328p. Simple

Hi @koresh I'm having problems with battery monitor. Trying to find out what's wrong, I have realiced that A6 analog reads from regulator output. So It allways reports 3,3V, isn't it?
Also, I read that unregulated could go up to 6,5V. Wouldn't this destroy radio module? I think I'm missing something.
Thanks.
-
Hi. Do you have unassembled pcbs to sell?
-
@gerator Oh.. so sorry. It is new forum reporting system. Didn't saw your message.
A6 reads unregulated voltage (3.5-6.5V) through divider (1/3). So it can't destroyed nothing.
-
@diogoc I will try to find them. But all of components are 0402...
-
@Koresh I still have a bunch of v1 boards that I never got to work because of power consumption (I presume). I thought I'd make one more attempt.
I tried bridging the jumper and I'm using a 2032 battery. Consumption varies between 2 and 4mA on different boards. On some boards it fluctuates a lot. The instructions above are not immediately clear. Do I have to remove the LDO AND capacitors as well?
-
while measuring current draw , was there FDTI adapter connected also?
-
@yury No I ran them on just a 2032 battery at the time, just had it in an external battery holder. I also removed the LDO on one of the boards and bridged the two top pads, with no apparent effect.
Unless there is something wrong with my DMM.
-
@bjornhallberg I have the same v1 board you have with a sleeping power consumption being 5uA. I also have Si1132 sensor soldered and had some issues with power consumption initially as the standard Si1132 lib did not implement sleep function for this sensor.
- what sensors do you have? Do they properly put to sleep? BH1760?
- can you share the sketch?
- removing the LDO will not help you to bring down consumption from 3mA. 3mA most likely mean your radio is not sleeping. Such consumption will kill CR2032 very quickly - no chance running the board on such consumption
- did you try a different multimeter?
- there could be a problem with one of the tantalum capacitor. @yury could you remind which one has to be removed please?
I suggest you start with 5)
-
@alexsh1 Thanks for the suggestions! Reassuring to know that you succeeded.
- I haven't added any sensors so it's just the default ones.
- https://github.com/EasySensors/ButtonSizeNode ... may need some cleaning up @Koresh or do we use v2 code for v1 sensor as well?
- I thought as much ... damn. I'm using the CW version radio with the adapter plate. I also thought about the radio but unlike the NRF radio this one should work with no counterfeit units?
No my other DMM was out of batteries.Found my old crappy DMM and it says the same, ~2mA.- I did remove both caps and it's still at ~2mA.
You're probably right about something not sleeping. Or else I've done a horrible soldering job on the four radios I've attached so far. All four sensors behave pretty much the same.
Also, at least on Domoticz they changed things around now so you have to use V_LEVEL instead of V_LIGHT_LEVEL or what? https://www.domoticz.com/forum/viewtopic.php?t=18577 With V_LIGHT_LEVEL I get some incomprehensible percent value reported.
-
-
No - please double check the board. There are options for a few sensors. Which ones do you have. Sensors on board.
-
Code really depends on sensors on board you have.
-
This is not about counterfeit radio. Just radio NOT SLEEPING. That's it.
-
OK.
-
OK
First thing first. Let's deal with your sleeping problem.
Identify which sensors you have on board or post a good quality photo of the board.

@alexsh1 I may have made a bit of a mistake with some glitchy chinese test probes. De-glitched cables and connected to a proper lab power supply gave very different readings (with the default git-sketch) ...
Still a bit confused over the differing readings. I get that the board I stripped from regulator and capacitors would perform better though. So do I have to do the same for all the other boards as well? Of course, I could save the worst performing boards for later and run them on 2xAA or something in places where space isn't an issue.
-
Hi @bjornhallberg.
I've done many tests today with your code. All tested boards were the newer ones. So I completely had no ideas until I read your last message. Now all is clear for me. You have battery draining ~10-100ua, not 1-2mA. As I see your boards contain 107J capacitors. It was an absolutely failed batch of capacitors. We resoldered all of these capacitors on all the boards after we had found this problem with @alexsh1. Unfortunatelly some of these boards had been sent until we found this problem. We are so sorry you had to deal with these failed boards. I suggest I send you some new tested buttonsized v1 boards to you. Also I can send good capacitors to rework failed boards and some of my new interesting boards for free.
-
@bjornhallberg @Koresh That's what I wrote a few posts above - start with the capacitors
My suggestion - get a decent DMM. Brymen BM235 or 121GW or any Fluke.
Measuring a sleeping current is challenging and some unexpansive Chinese DMM manage it just really well. BUT! You do not want to waist your time just because your meter is crap and was completely off on some readings.
-
@koresh Package went under the "Postnord" radar! Woohoo, perfect! I will start replacing the old capacitors and finally be able to deploy the sensors. Very nice of you to include some product samples as well. Really excited about these sensors!

Hi guys, quick question: I'm using a LiFePo4 3.2V battery directly on the board (sensors part removed).
Somehow the battery percentage always shows 100 - how should I change the default code to make this work?Right now I'm using the code like here: https://github.com/EasySensors/ButtonSizeNode/blob/master/ButtonSizeNode.ino
-
@christoph-blank Hi, thanks for using this board. In the first version of this board the divider is conected after LDO, so you can't measure voltage above 3.3V. In the second version the divider is connected to the battery directly. You use 3.2v battery so it is not problem for you. But LiFePo4 battery has very flat discharge curve so it can be hard to read this level with reasonable accuracy.
I will try to find LiFePo4 battery and add some piece of code soon. Yet you can play with followed code// Get the battery Voltage int sensorValue = analogRead(BATTERY_SENSE_PIN); // 1M, 470K divider across battery and using internal ADC ref of 1.1V1 // ((1e6+470e3)/470e3)*1.1 = Vmax = 3.44 Volts /* The MySensors Lib uses internal ADC ref of 1.1V which means analogRead of the pin connected to 470kOhms Battery Devider reaches * 1023 when voltage on the divider is around 3.44 Volts. 2.5 volts is equal to 750. 2 volts is equal to 600. * RFM 69 CW works stable up to 2 volts. Assume 2.5 V is 0% and 1023 is 100% battery charge * RFM 69 HCW works stable up to 2.5 volts (sometimes it can work up to 2.0V). Assume 2.5 V is 0% and 1023 is 100% battery charge * 3.3V ~ 1023 * 3.0V ~ 900 * 2.5V ~ 750 * 2.0V ~ 600 */ #ifdef MY_IS_RFM69HW int batteryPcnt = (sensorValue - 750) / 1.5; #else int batteryPcnt = (sensorValue - 600) / 3; #endif

The above code is what I currently use, and I removed the sensor part of the module. However, it shows 100% until the end (until it's not sending anymore).Looking forward to your tests!
