Support for the Adafruit Feather M0.
General information¶
Feather M0 boards are development boards shipped by Adafruit.
All the feather M0 boards are built based on the same Atmel SAMD21G18A microcontroller. See Atmel SAMD21.
Several types of Feather M0 boards exist: Feather M0 WiFi Feather M0 BLE Feather M0 Adalogger Feather M0 LoRa
The different modules used to differenciate the boards (ATWINC1500 WiFi, Bluefruit LE, SD card, LoRa) are connected via SPI (spi.h::SPI_DEV
) to the SAMD21 mcu.

Accessing STDIO via UART¶
To access the STDIO of RIOT, a FTDI to USB converted needs to be plugged to the RX/TX pins on the board.
