wwintjong/macropadMy take on a macropad that I think will suit me. The layout is a 5x4 keys with hot-swappable switch and LED. Current iteration has no knobs or display implemented, but that is an idea for future versions.
Macropad is an open-source printed circuit board by wwintjong, from the wwintjong/macropad repository on GitHub. It is a 2-layer board of 183 × 126 mm with 116 parts on 103 nets, routed with 261 tracks and 0 vias.
It is built around the RP2040, 74AHCT1G125SE and W25Q128JVSIQ, with the SRV05-4 and SK6812MINI-E among its other parts. Its parts include 37 capacitors, 21 diodes, 21 switches, 20 inductors and 8 resistors. It belongs with the keyboards and input boards and the RP2040 boards of this library.
My take on a macropad that I think will suit me. The layout is a 5x4 keys with hot-swappable switch and LED. Current iteration has no knobs or display implemented, but that is an idea for future versions. Next step is to design enclosure for the pad.

LucasLHenry/spelltwister
This is the third version of the code for the Spelltwister module with CCTV. This version uses the Arduino platform and the RP2040, a chip developed by Raspberry Pi for their RPi Pico board.
It measures 183 × 126 mm and has 2 copper layers, 1.6 mm thick.
116 parts, built around the RP2040, 74AHCT1G125SE, W25Q128JVSIQ and SRV05-4. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
From the wwintjong/macropad repository on GitHub, at the commit this page was made from: the board is macropad-backups/macropad-2026-08-05_133935/macropad.kicad_pcb and its schematic capacitor.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Its repository states no licence, so its author keeps all rights: ask wwintjong before reusing the design.
