CAN Bus Interface
The BeagleBone CANBus Cape uses an RSZ-3.305HP to provide isolated power sources
for the CAN transceiver ISO1050. ISO1050 is a galvanically isolated CAN transceiver
that isolates grounds and prevents noise currents from entering local ground. The bus side
of the transceiver is connected to a D-Sub 9 connector and provides an option to install a
terminal resistor. The controller side of the transceiver is connected to DCAN1 port of
AM335x on BeagleBone.
