4 Connectors

4.1 Power connector (X7)

The following figure shows the power connection jack X7. This connector is used to connect
an external unregulated DC power supply voltage (9V-15V DC) to the evaluation board.
Connector X7:

4.2 MCU pin header connectors (X1 and X2)

All pins (except oscillator and supply pins) of the microcontroller are directly connected to pin
headers. Pin 1 of the MCU corresponds to Pin 1 of the connector. Pin 2 of the MCU
corresponds to Pin 2 of the connector, and so on.

4.3 LIN-UART connectors (X5, X9)

Two 9-pin D-Sub female connectors are used for the serial interfaces. Note that X5 and X9
are shared between the RS232- and LIN transceivers and must be configured to the desired
functionality (refer to chapter 3.9 for details).
