Everybody has used a Raspberry Pi pico, that was my go to for most of the simple projects as well, one thing that always bugged me was the battery which I had always had to charge after a couple of days of using my project, thats why I am planning to build a custom devboard with on board battery charging system
That is pretty easy, you have all the files you will need in the production folder, order the development
board from any PCB fab ( I chose JLC cause its cheap and has good quality ) and BINGO! You will have itt
to use for any purpose you want!!
You can use it as any normal RP2040 Devboard, enter the boootloader mode
by holding the BOOT buttom while connecting to your device, flash it withh
firmware and you are good to go!!
