5 Connectors
5.1 Power connector (X12)
The following figure shows the power connection jack X12. This connector is used to
connect an external unregulated DC power supply voltage (9V-12V DC) to the evaluation
board.
Connector X12:
It is recommended to use 9V DC input to minimize the power dissipation of the voltage
regulators.
5.2 Edge connector (X1, X2)
All pins (except oscillator Pins) of the microcontroller are directly connected to X1 and X2 as
follows:
Connector
MCU Pins
X1 (1 – 50)
1 – 50
X2 (51 – 100)
51 – 100
The odd pin numbers are located on the one side and the even pin numbers are located on
the other side of the connector.
5.3 UART”A”, UART”B” connector (X3, X5)
Two 9-pin D-Sub female connectors are used
for the serial interface UART”A” and UART”B”.
TXD is the transmit output, RXD is the receive input.
The DTR or RTS signal can be used to generate a reset.
Please use a 1:1 cable for PC-connection.
Connectors X3, X5:
