CAN Connectivity (X65, JP3)
The Controller Area Network (CAN) bus offers a low-bandwidth, prioritized message
fieldbus for serial communication between microcontrollers. It efficiently supports
distributed real time control with a high level of security. The DCAN module of the AM335x
implements the CAN protocol according to the CAN 2.0B protocol specification and
supports bitrates up to 1 Mbit/s.
The CAN1 interface of the phyBOARD-Wega AM335x is accessible at connector X65 (2×5 pin
header, 2.54 mm pitch).
Jumper JP3 can be installed to add a 120 Ohm termination resistor across the CAN data
lines if needed.
