Key Features
- Brain: Powered by the compact and capable Arduino Pro Micro.
- Firmware: Runs on QMC Firmware for incredibly easy keymap customization without needing to recompile.
- Display: Integrated 0.96" OLED (128×64) for real-time layer feedback, stats, or custom graphics.
- Matrix: A clean 4×3 Key Matrix layout complete with diode orientation for robust anti-ghosting.
- Encoder A rotary encoder with push button for changing volumn.
- Function With fn feature it has total 12+12 = 24 working Keys
Hardware Design
This project was built entirely from scratch, bridging custom PCB design with 3D modeling.
Credits & Acknowledgments
This project wouldn't be possible without these incredible open-source tools and communities:
- KiCad for the phenomenal open-source PCB design suite.
- Autodesk Fusion 360 for the case design environment.

Questions
How big is the Macropad pcb PCB?
It measures 119.1 × 85.7 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Macropad pcb use?
27 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 pcb KiCad files?
From the CodeR3836/Macro-Pad repository on GitHub, at the commit this page was made from: the board is Circuits/PCB/macropad_pcb.kicad_pcb and its schematic Circuits/Schemetic/macropad.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Macropad pcb 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).
