A Controller Area Network (CAN bus) is a vehicle bus standard designed to allow microcontrollers and devices to communicate with each other in applications without a host computer. It is a message-based protocol, designed originally for multiplex electrical wiring within automobiles, but is also used in many other contexts.

External pinout

UDOO Neo exposes two ports on the external pinout:

TX RX
CAN_1 41 40
CAN_2 43 42

By default these pins are assigned to the A9 core, configured as GPIO. In order to use the pins for a CAN bus, they must be explicitly configured.
