The firmware is Keyberon, a pure rust firmware.
The goal was: build a custom keyboard from scratch continue to learn embedded rust * have fun
ortholinear 60 keys, using Cherry MX switches, only 1U keycaps; 4 RGB LEDs for status; 6 RGB LEDs for backlight; USB-C connector; 1 STM32F072 MCU, with hardware USB DFU bootloader; Only onboard SMD component (except for the switches). ESD protection

Pouetpouet board r2: common questions
What microcontroller does the Pouetpouet board r2 use?
The Pouetpouet board r2 is built around the STM32F072CBT6, from the STM32 family.
How big is the Pouetpouet board r2?
The Pouetpouet board r2 measures 232.6 × 109.6 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the Pouetpouet board r2?
84 components, from 13 distinct parts. The full bill of materials is listed on this page.
Where can I download the Pouetpouet board r2 design files?
From the dkm/pouetpouet-board-r2 repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.
Can I use the Pouetpouet board r2 design in my own project?
