We will use the next generation Arduino M0 Pro for this course. Its core is an ARM Cortex M0+ processor which make it faster and more powerful than the Arduino UNO based on the AVR-8-bit core.

The CPU used is ATSAMD21G18 having been designed by the former company Atmel which now has been taken over by Microchip.

Please follow the instructions on Getting started with the Arduino M0 Pro.
