From the project

4-key macropad + EC11 encoder + OLED, XIAO RP2040, KMK firmware. Submitted to Hack Club Hackpad YSWS.

A 12-key macropad with a rotary encoder and an OLED display, built on a Seeed XIAO RP2040 and running KMK firmware. Submitted to Hack Club's Hackpad You Ship, We Ship program.

v2 — the most loaded build that fits the Hackpad rules at once: 12 MX keys, 1 EC11 rotary encoder, 1 OLED display, and every usable GPIO on the XIAO consumed (11 / 11). 13 inputs, well under the 16-input cap; 95 × 95 mm board, well inside the 100 × 100 mm size cap.
