USB numpad PCB with standard layout, extra keys, and macro support. Supports the most popular open source keyboard firmware. Requires 21 switches (MX or Alps), 21 keycaps, and a case (can be used without a case).
STM32F103C8T6 microcontroller, USB-C port. Access the bootloader by holding backspace (top-right key) while plugging in the board.
PCBs may have small imperfections due to manufacturing or soldering.
The renders do not show the USB port because it is not available as a KiCad model.
