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:
The switching mode voltage regulators allow a wide input range. This might be of interest
when using Vin to power the LIN bus Vs line.

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 3.4 for details).
