This is a custom dev board made by me. I am just starting to design PCBs. V2 is coming soon.
In the project working screenshots, you can see that I did not order the PCB yet, but the devlogs, schematic, and PCB layout show that everything is correctly connected. Because this is a hardware project, the experienceable URL is essentially the README.
This board is an Arduino-based board, so it can do most of the things an Arduino can do (although it does not have a battery management system). The board follows the layout of a Raspberry Pi Pico.
