Getting Started
- Download PCB files and edit them according to your own need
- Download QMK MSYS
- Install Python and run
python3 -m pip install qmkand then runqmk setupin terminal - Download Brokiepad.uf2
- connect your macropad with a pc using a cable
- Hold the boot button on the RP2040 board.
- Keep holding it while you plug the USB cable into your PC, then release the button.
- A drive named RPI-RP2 appears in File Explorer.
- Drag and drop your .uf2 file onto that drive.
- The drive disappears by itself after a few seconds and the board reboots as your macropad.

Questions
How big is the Hackpad PCB?
It measures 71.1 × 94.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Hackpad use?
44 parts, built around the SK6812MINI-E. 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 Hackpad KiCad files?
From the husnainxali/hackpad repository on GitHub, at the commit this page was made from: the board is pcb/hackpad.kicad_pcb and its schematic pcb/hackpad.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Hackpad 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).
