 # Arduino core support for STM32L082-based boards
 
-This repository is MCCI's version of [Arduino_Core_STM32](https://github.com/stm32duino/Arduino_Core_STM32), adapted for the STM32L082. The BSP here targets the STM32L082 as used in the Murata CMWX1ZZABZ LoRa® module, as further in the MCCI Catena® LoRaWAN® technology boards. Several of these boards are closely compatible with the Adafruit Feather M0 LoRa. See [Supported Boards and CPUs](#supported-boards-and-cpus) for more info.
