This is a small macropad keyboard I built, mostly for controlling my music while working.
It includes:
- KiCAD schematic and PCB design.
- OpenSCAD case and top plate designs.
- Custom Rust firmware for the STM32F042 microcontroller
- Bill of materials, of all the components used.

Questions
How big is the Micropad PCB?
It measures 45.1 × 76.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Micropad use?
34 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 Micropad KiCad files?
From the blakesmith/micropad repository on GitHub, at the commit this page was made from: the board is hardware/micropad/micropad.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Micropad design in my own project?
Its repository states no licence, so its author keeps all rights: ask blakesmith before reusing the design.
