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.

4.2 MCU pin header connectors (X20A, X20B, X21, X22 and X23)
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.
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).
