Detailed Description

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_DEV(0)) to the SAMD21 mcu.

Pinout

Flash the board

1. Put the board in bootloader mode by double tapping the reset button.
   When the board is in bootloader mode, the user led (red) oscillates smoothly.
2. Use BOARD=feather-m0 with the make command.
   Example with hello-world application:

   make BOARD=feather-m0 -C examples/hello-world flash

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.
