About anne-key

Alternative firmware for the Obins Anne Pro keyboard, written in Rust. The project aims to provide a more stable and feature-rich replacement for the original firmware. Currently supports basic keyboard functionality, Bluetooth operation, LED control (on/off and theme switching), USB charging, and partial communication with the Anne Pro app. It can be flashed as a drop-in replacement via DFU. The firmware is under active development and is not yet recommended as a primary daily driver due to missing features such as concurrent USB/Bluetooth, media controls, custom lighting and keymaps, and power management.
