==CAN ==
=== Description ===
The CAN interface available on the Evaluation Kit at the connector J23.
J23 is a 3x2x2.54mm header that provides the CAN bus port compatible with CAN with Flexible Data Rate (CAN FD) 2.0B protocol. The CAN transceiver is implemented on the AURA SOM.

=== Device mapping ===
CAN device is mapped to <code>can0</code> device in Linux. The peripheral can be configured using <code>ifconfig</code> and <code>ip link</code> utilities.
=== Device usage ===
Inserting a jumper on pins 1 and 2 enables 120Ω bus termination.
