BOARDS WE MAKE OURSELVES.
Boards built around what we kept watching people struggle with: rebuilding the same power supply, looking up the same pinout, and having no safe way to learn to solder.
GPIO Card
REV A1
Pi 4 & 5 pinout, on the header
A slotted card that drops over the Pi's 40-pin header and stays there while you wire. Every pin named, numbered and colour-coded by function.

Solder School
REV A7
Learn to solder, level by level
Four levels from big through-holes down to 0.65 mm SMD and an SO-8 chip — 108 practice joints that connect to nothing, so nothing you do there can break anything. Then a finish line of 20 joints that has to work: hold the button and three LEDs and a buzzer tell you whether it does.
