Put Rust in your keyboard
summary
RMK is a Rust keyboard firmware that provides a platform-agnostic core (input drivers, event processors, HID reporter) plus a CLI generator, ARMKit CLI, and a simple TOML config file keyboard.toml that emits working Rust firmware. It uses embedded-hal traits for portability across ESP32, STM32, RP2040 and nRF52, runs async and low-power with embassy async, has unit-tested keyprocessing, USB (usbd) and BLE (bt-hci) reporters, live keymap updates via v support, and lists RGB and display as TODOs.
