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:


Depending on interest, group buy may include four different types of cases:

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.
