Easy/Newbie PCB for MySensors

[ileneken3]

@sundberg84

It's definitely easier with a booster - but not cheaper or more reliable. (Why does the booster cost more than the Arduino?)

Everything is about tradeoff's. When you solve one problem, it can easily introduce another. At first, I ignored the whole booster thing. But after a lot of experiments, I ended up with a pile of 1.35 V batteries. So I tried the booster, and ended up with transmission problems (partially solved by capacitors). So then I tried changing the bootloader (1Mhz, no brown out), and it seems to be OK - but I know there will be other problems. Example: I now need to boost to 3.3V for sensors that require it. Also, are there compatibility problems with mysensors?

Even still, thanks for the great board - I've had a lot of fun and learned a lot with it!

[sundberg84]

@ileneken3 - you are so right, and that is the fun with electronics! There is no right or wrong (more or less)!
Newbie/Easy PCB is what it sounds like and my only aim is to make it as easy as possible. Im happy to evaluate it but at the moment booster and a few non compatible sensors is the price i pay.

I have probably 15 of these PCB with boosters now, and yes - there are times when the booster makes it unreliable but most of the times it works. I have maybe trashed 5 nodes in all which is fair less amount that I had to trash soldering wires. I have also tried bare atmegas in different shapes and even with them there are problems (not including flashing bootloaders and stuff you dont have to do with EasyPCB).

We also needs to remember this is DIY, not factory manufactured which can introduce alof of errors. We learn as we go and I hope EasyPCB can be a great platform for new people like you said. Nice to hear, thank you!

Yesterday I have received Rev 9 of Newbie PCB board. I am a newbie and I purchased this board to make building easier. I have soldered a radio and Arduino Pro Mini 3.3 V to it and the radio module with a 47uF cap. The power is supplied using the FTD232 board. Because the radio module is not powered using the 3.3V of arduino I wired this using a separate wire. I also connected a DTH 11 with the resistor on the board (4K7). I used a test sketch to read the DTH 11 and this is working well.

When I load the MySensors sketch I get a radio failure. I have no Idea what this is? Bad wiring, not correct power?? Anyone can help me started?

@martim said in Easy/Newbie PCB for MySensors:

Because the radio module is not powered using the 3.3V of arduino I wired this using a separate wire.

Can you show a picture of your setup and give more explanation on this sentence ? This part about connection of the radio smells fishy ;)
It seems the radio cannot be initialized, so I suppose the power supplied to it is not correct, but I'm not sure of what you did.

[martim]

This is the front part. The connected cable goes to the FTD232 which also is currently the power supply.

!

The red wire on the back plane connects the plus from arduino to the plus for the radio (soldered on the + of cap)

@martim - read the insctructions again.
If you are using the board with a 3.3v arduino and battery you need to connect the BAT jumper and use a booster.

If you are using a 3.3 arduino with a regulated power you can add a jumper/wire over the booster and connect the BAT jumper.

[martim]

@sundberg84
Ok, Thanks I will try the second suggestion. (my booster is still not delivered and hard to get at the moment :()

[martim]

Found one issue. On the PCB board the was a very small broken wire. I think the postman was not very careful with it. At least I have some better logging but still not there.

How can I solve this one?

Does this mean the gateway does not reply? It does with other sensors?

[sundberg84]

@martim - yes, it doesnt get the connection to the GW as it wants... might be node or gw. Do you have caps on both?

[martim]

Have solved the issue. Removed the cap from the board and directly soldered to the Radio Board. That's was solving the issue.

[hiddenuser]

Awesome board!!!
How do I access A2, A3 and D8?

Thanks a lot

[sundberg84]

@hiddenuser - they are not accesses through the PCB:

You need to solder a wire on the Pro Mini and run somewhere, like the prototyping area.

[hiddenuser]

@sundberg84 Thanks a lot.... My ebay seller sent me a Atmega168 5v. I have noticed that you boards supports 5v version too. Would I be able to power it using raw (12v).

Thanks a lot .

[sundberg84]

@hiddenuser - as long as the voltage divider on the board supports 12v that will work. A warning on the cheap chinese stuff is that this voltage regulator is bad and might fry.

[achurak1]

@sundberg84 - thanks for your board, it seems to be almost exactly what I was looking for! What do you think would be the best way to adjust it if I need to boost the batteries not only to 3.3V, but also to 5V to run the pir sensor?

[sundberg84]

@achurak1 - do you mean running 5v on batteries? Sorry - thats out of my knowledge.
I guess there are 5v boosters but my guess is also that this will drain the batteries pretty fast.
I have made test with 9v batteries and voltage regulaters and this has worked for some time but never gives the lifetime as 3.3v on 2xAA.

[achurak1]

@sundberg84 - correct, the 5v booster looks exactly like the 3.3v booster. I have another sensor I've built manually and it works exactly like that, arduino/temp/hum/radio all work from 3.3v and pir works from 5v. I power it all with two rechargeable batteries (so ~2.6 max charged, not even 3) and it's been running good for several months already and still shows 2.45-2.50.

[gohan]

@achurak1 do you know you could modify the pir sensor to work directly from batteries by removing the regulator?

[achurak1]

@gohan - I tried to connect the 3.3v to one of the three pins where you'd usually put a jumper (H, L pads) as I've seen people discussing it on this forum and it just didn't work for me, the sensor did work, but very unstable, would fire up every time radio sends or receives something.

[gohan]

Because you need to add an extra AA battery to increase voltage to around 4,5v just for the pir sensor
