Blueberry Pi Mini
A devboard to help me learn how to make devboards. Basically just follows the guide, but with a few good modifications.

finished schematic, started pcb
Today I both started AND finished the schematic! To differentiate my devboard I decided to go the "mentally unstable" route and make the pinout match the Pi 4b instead of the Pi pico. Therefore its also a 2x20 header. Why anyone would want this is beyond me but who cares, it was fun to make and gets me to prototype hopefully! (small note: the 5V pins that would normally be on Pi 4b are replaced with GPIO 28/29.)
