Interest Check Form (https://forms.gle/AP5QhmwLvabQb4MG9)
Hello GeekHack,
I have been working on a numpad/macro-pad that fits a niche I haven't seen filled yet: open-source PCB, support for the QMK firmware, and no microcontroller board necessary.
The latest prototype, v0.9, adds per-switch LED support, RGB backlighting, and has a smaller PCB. It is also Certified Open Source Hardware! (https://certification.oshwa.org/us000643.html)

GitHub Repository (https://github.com/inexcomp/NumpadA)
USB numpad with standard layout, extra keys, macro support, in-switch LEDs, and RGB backlighting. Will support the QMK firmware on launch. Requires 21 switches (MX, Alps, Choc), 21 keycaps, and a case.
STM32F103C8T6 microcontroller, USB-C port. Access the bootloader by holding backspace (top-right key) while plugging in the board.
Features include:
- Full n-key rollover
- Standard PC numpad layout for keycap compatibility, with an extra row spaced 1/3u up.
- Fully programmable, with macro support and Fn key.
Depending on interest, group buy may include four different types of cases:
- FR4 sandwich-style plates
- Stacked acrylic case and plates
- Machined aluminum case and plates
- 3D-printed plastic case and plates
All of the case files will be released under open-source licenses, so you can manufacture your own case variants like wood cases.
The price is targeted at around $25-30 for the PCB with all components. This may change depending on the features requested by the community.
