5 Connectors
Pin assignment and employment of 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 (9 V - 12 V DC) to the evaluation
board.
Connector X12:
It is recommended to use 9 V to keep the power dissipation to a minimum. Otherwise, an
additional heat sink for the linear voltage regulator might be necessary.
5.2 MCU pin header connectors (X1, X2)
All pins (except oscillator and supply pins) of the microcontroller are directly connected to pin
headers.
Connector
X1 (1 – 32)
X2 (33 – 64)
On the PCB, the corresponding pin numbers of the µC are written next to the connector pins.
5.3 UART"A", UART"B" connector (X3, X5)
Two female SUB-D9 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 1:1 cable for PC-connection.
