DVK90CAN1 Hardware User Guide
CAN
The AT90CAN128 is a micro-controller with an on-chip full-CAN controller.
The DVK90CAN1 is supplied with an ATMEL CAN transceiver (ATA6660). A male DB9
connector assumes the CAN bus connections.

Figure 3-15 . CAN DB9 Connections
If a network termination is needed (CAN baudrate higher than 100 Kb/s), J10 switch
inserts a 120 ohms resistor between CAN-H and CAN-L.
