Overview
Macropad is an open-source printed circuit board by realBoltDev, from the realBoltDev/macropad repository on GitHub. It is a 2-layer board of 42.7 × 62.7 mm with 9 parts on 19 nets, routed with 53 tracks and 0 vias.
It is built around the SK6812MINI-E. Its parts include 4 switches, 3 diodes, 1 resistor and 1 IC. It belongs with the keyboards and input boards and the RP2040 boards of this library.
Main components
1README
README.mdMacropad
A custom 4 key macropad with 2 SK6812 Mini LEDs. It has a power LED with a resistor, and uses KMK firmware.
It was truly a fun and amazing learning experience for me making this macropad as it was my first project where I designed schematic & PCB with KiCad and the 3D case with Autodesk Fusion.
Features:
- 3D Case
- 4 Keys
- 2 Mini LEDs
- 1 Power LED (turns on when board is powered)

Questions
How big is the Macropad PCB?
It measures 42.7 × 62.7 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Macropad use?
9 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 Macropad KiCad files?
From the realBoltDev/macropad repository on GitHub, at the commit this page was made from: the board is pcb/Macropad.kicad_pcb and its schematic pcb/Macropad.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Macropad design in my own project?
Its repository states no licence, so its author keeps all rights: ask realBoltDev before reusing the design.
