This is a 25x25mm board intended for integration into other projects based on RP2040.

A cute little buck converter. Takes up to 18V input and provides 5V output. Pin compatible with the venerable 7805 linear regulator, and includes an optional enable pin.

A very familiar-shaped development board featuring a number of Mike's smol boards. RP2040smol provides microcontroller magic, while AP62250smol and optionally Charjsmol have the power supply covered.
