Arduino Uno¶
Support for the Arduino Uno board.
Overview¶
The Arduino Uno is one of the cheapest board to start and discover with electronics and embedded coding. It is based on Atmel’s AVR architecture and sports an ATmega328p MCU. It is like many Arduinos extensible by using shields.

Flashing the device¶
Flashing RIOT on the Arduino Uno is quite straight forward, just connect your Arduino Uno using the programming port to your host computer and type:
make BOARD=arduino-uno flash
This should take care of everything!
We use the open avrdude tool to write the new code into the ATmega328p’s flash
Caution¶
Don’t expect having a working network stack due to very limited resources.
