@4994james or just use internal vcc measurement as described on the same page. That saves you the voltage divider.
I wrote a convenient library to measure vcc internally : https://github.com/Yveaux/Arduino_Vcc
@NeverDie Perhaps but the design is a bit too simple and unoriginal. I'd have to clean up the files a bit and I haven't touched Eagle since I made this board several years ago.
@Michael-Link I have been out of touch with MySensors for some time now and looking to slowly get back into it. I created this and a few other boards back in 2018 All of the GERBER files for this are in the "Design Files" tab. Those you should be able to send to JLC PCB or one of the other fab houses and have some made. This was designed to be used with 2 other boards that I designed. There was the processor board and the power supply board. The processor board was designed in a way that I could use a couple different switch boards. This one and a universal multi-switch board that had multiple configurations. If you look here you will see my other boards.
