A 4-key macropad with a rotary encoder and OLED display, built around the Seeed XIAO RP2040.
Features
- 4 Cherry MX-style mechanical switches
- Rotary encoder with push-button (volume up/down + mute by default)
- 0.96" 128x64 SSD1306 OLED display showing a pixel-art cat that reacts to typing speed (sleeps when idle, walks at normal pace, runs when typed quickly)
- Custom 3D-printed two-part case (base + lid)

Questions
How big is the Macropad v1 PCB?
It measures 80 × 84 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Macropad v1 use?
7 parts. 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.
Where can I download the Macropad v1 KiCad files?
From the deshnaarun/Macropad repository on GitHub, at the commit this page was made from: the board is pcb/Macropad_v1.kicad_pcb and its schematic pcb/Macropad_v1.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Macropad v1 design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
