The HackClub Micropad is a compact, USB-HID macropad intended for programmable shortcut input. It was designed from scratch in KiCad and manufactured via JLCPCB. Firmware runs on CircuitPython. It is a keybord with a programmable OLED screen, 6 keys, and a rotary encoder. It is a fun, memorable, and beginner friendly productivity tool.
Key features:
- Seeed Studio XIAO RP2350 microcontroller
- Mechanical key switches (MX-compatible footprints)
- Rotary encoder with push-button
- Onboard NeoPixel (WS2812B) RGB indicator
- USB-C connectivity via the XIAO module
- 3D-printed enclosure (FDM, PLA)
