6 Connectors

6.1 Power connector (X15)

The following figure shows the power connection jack X15. It is used to connect an external
unregulated DC power supply voltage (9V-15V DC) to the evaluation board. Higher input
voltages are possible, but cause higher heat dissipation of the voltage regulator U6,
depending on the total load current.
Connector X15:
It is recommended to use 9V DC input to minimize the power dissipation of the voltage
regulator.
6.2 Edge connectors (X1 – X4)
All pins (except oscillator pins) of the microcontroller are directly connected to the edge
connectors X1 to X4 as follows:
Connector
X1 (1 - 36)
X2 (37 - 72)
The odd pin numbers are located on the outer side and the even pin numbers are located on
the inner side (closer to the MCU) of the connectors.

6.3 UART0- UART2 connectors (X5, X6, X7)

Three 9-pin D-Sub female connectors are used
for the serial interface UART0-2.
TXD is the transmit output, RXD is the receive input.
The DTR signal can be used to generate a reset.
Please use a 1:1 cable for PC connection.
