= Hardware Abstraction Layer (HAL)

Embassy provides HAL's for several microcontroller families:

* `embassy-nrf` for the nRF microcontroller sfrom Nordic Semiconductor
* `embassy-stm32` for STM32 microcontrollers from ST Microelectronics
* `embassy-rp` for the Raspberry Pi RP2040 microcontrollers

These HALs implement async/await functionality for most peripherals while also implementing the async traits in Embassy.
