      • Supported Hardwares

      Leveraging the great Rust embedded ecosystem, RMK is able to support a wide range of hardware across different architectures, including Cortex-M, Xtensa, and RISC-V.

      Below is a (non-exhaustive) list of the currently supported hardware:

      Adding Support for New Hardware

      RMK can run on any hardware platform with Embassy support. To enable specific communication:

      • USB Support: Requires implementation of embassy-usb-driver traits.
      • BLE Support: Requires implementation of bt-hci traits.

      Once your hardware has the corresponding trait implementations, RMK support will be available out of the box.
