## What it is
Keyberon is a pure Rust, no_std crate providing building blocks for creating custom keyboard firmware. It uses embedded-hal for GPIO key scanning and usb-device for USB HID communication, letting users compose only the features they need.

## Use cases
- write custom keyboard firmware in rust
- build a handwired split ergo keyboard
- implement layers and tap-hold behavior on a custom mechanical keyboard
- create usb hid firmware for an stm32 microcontroller
- replace qmk with a rust-based firmware
- add keyboard matrix scanning to an embedded project

## When to choose
- you want to write keyboard firmware in pure Rust on stable toolchain
- you need a no_std, composable library rather than a monolithic firmware
- you are building a custom or handwired keyboard on an MCU supported by embedded-hal and usb-device

## When to avoid
- you want a ready-made firmware with a large config ecosystem like QMK/ZMK without writing Rust
- your MCU lacks embedded-hal GPIO and usb-device support
- you need wireless/BLE keyboard support out of the box

## Facets
- artifact type: library
- maturity: active
- function: embedded, sdk, middleware
- domain: embedded-systems, hardware, developer-tools
- platform: embedded, rust
- tags: keyboard-firmware, usb-hid, no-std, embedded-hal, rust, qmk-alternative
