Overview
This xCHIP forms part of the core modules. The SAM D21 from Microchip Technology Inc is a low-
power microcontroller using the 32-bit ARM® Cortex ® -M0+ processor with up to 256 KB Flash
and 32 KB of SRAM. This module is compatible with the Arduino platform due to the shared
architecture with the Arduino M0.

Arduino
See Getting Started with the CC03 for Arduino programming.
More info:
Choose Arduino/Genuino Zero (Native Port)
If you are using the IP02 to program your CC03, then these are the settings:
The A/B switch is in position B
The DTE/DCE switch is in position DCE
(If you battle reading the small print, both switches should be in the position
closest to the USB port (away from the CC03))
If you want to print to serial, the use Serial USB
You can add a line to your code at the top if your code already uses Serial
everywhere:
#define Serial SerialUSB
