💬 Easy/Newbie PCB for MySensors
-
@sundberg84 I have now a node running with the BAT link removed, the REG link attached and I have used the Arduino_Vcc library.
The battery report are consistent with the battery voltage measured with a digital volt meter.
EDIT: Code below had a bug in it, I have fixed the bug and updated the code. The bug affected the temperature readings
So, to run the RFM69 board on two AA batteries I have done the following:- Removed regulator and led from Arduino
- Burned a new bootloader with a 1.7 volt BOD
- Put a link in REG position
- Solder radio to board
- Solder antenna to board.
- Solder BME280 to power and A5, A6
And that's it.
Here is my code:

Let us know how it turns out :)
Any pictures of this you can share?I did see you put VccMin to 1,2V and this might calculate so the battery will be @ 30% when the BOD hits you. I would put this to 2.0v if you are using a internal 8mhz bootloader. https://forum.mysensors.org/topic/7296/how-to-burn-fuses-so-that-pro-mini-3-3v-would-go-down-to-1-8v-solved/15

@sundberg84 Hi, I soldered a board holding a humidity and temperature sensor. That is working fine and reporting to may gateway (mqtt). Only thing which I do not get working ok is the battery level measurement. As I already posted in an other topic here.
Here are some pictures of my board. The bat jumper is connected with a wire on the bottom. And the code I use on it right now.
I already changed the pro mini for a fresh soldered one but still getting the the same result. Just ones giving the volt and % and after that only giving 0 volt as output.
tried to include delay(500) in the sketch but that did not help.

Can you measure the voltage on Booster-Vout and also on this pad.

@mr_sensor - I can not see any errors on the pictures you posted.

Also, Just for my info, does it matter how the resistors or capacitors are soldered on the board? My biggest problem is always determine the right resistors value and the right way to solder them (+ -). On the pcb some of them are coded (very handy for me as a beginner) with a G but not all of them?
So my worry was that I maybe have soldered the "battery measurer" ones in the wring direction? Could that be the problem here? -
Resistors can be soldered either way, but if you read 0v on that capacitor pin it mean you have a problem between the battery and the capacitor, so you have to backtrack the connection that is missing

I measured the capacitor again and get a 0,10 output.
-
Capacitor value does not change the voltage. The resistors does... I would double check that you use the right resistors. For example it's easy to use a resistor marked 1k instead of 1M. With 3.3v you should have around 1v on the capacitor.
-
@gohan said in 💬 Easy/Newbie PCB for MySensors:
you are also missing the capacitor on the booster output for better stability
Ok, I assumed it was not needed when using a battery. Which one to use there?
@mr_sensor a advice is to measure the resistance again over the resistors.

@sundberg84 Well I tried that but did not get the measurement straight from the pcb si I decided t solder a new board using the right capacitor this time (0,1uf instead of 1uf) made sure using the right resistors as well and adding a capacitor after the booster. Than with the same mini pro from the other board tested again and wow it is working as intended.

It looks like you are only sending the % and not the voltage? -
@Mr_sensor It happened to me once that capacitor was just shortening the circuit, it was a smd, but when I removed it and tested it it was constantly making shortage, thus the circuit was never working and luckily my power supply had a low enough protection.
I examined cap very closely, all looked fine, but internally it was not working fine.Since most of us (well, me at least) are buying cheap components I made it a habit now to always measure every passive component before installation, partly eliminates one variable

A short sneak-peak on the upcoming revision...
Still a long way to go...
Rev 10 - Nrf24l01+ ed.
- Completley redesigned in KiCad.
- MysX location changed to accept more MysX boards and align like RFM version.
- Optional signing added
- Optional SPI flash added.
- Extra pins aligned to 2.45 vertical & horisontal
- Relocated Extra + Bat Measurer some to allow more space to booster
- Changed pull-up resistor from D3 to D5 to have one more pin for Interrupt
- Relocated D5 pullup, MysX and IRQ jumper some.
- Changed footprint (silk-screen) on capacitor to easier show Gnd/Pos side.
Need to change footprint on voltage regulator on both nrf and rfm edition back to a square and not a liniar one. (rev 9 change). Not intended to revert back.
Also a bit worried the 4,7uF cap os to far away from radio.

Putting it underneath the nrf24 module? I know it is not a "clean solution" but there would be still be unused space under the radio module
