3.2. CAN configuration

The EVB has two NXP TJA1041T high speed CAN transceivers and two female standard DB9
connectors to provide physical CAN interfaces for the MCU.

The pinout of the DB9 connector (J2) is shown in the figure below.

Figure 5. CAN DB9 connector pinout

For flexibility, the CAN transceiver I/Os are also connected to two standard 0.1” connectors (P4 and P5)
at the top side of the PCB. The pin-out for these connectors is shown in the figure below.

Figure 6. CAN 3pin header interface connector

By default the CAN interfaces are not enabled. To enable the CAN interfaces the jumpers detailed in
Table 3

need to be placed.
