Chapter 7 Connectors
7 Connectors
7.1Power connector (X1)
The following figure shows the power connection jack X1. This connector is used to connect an external unregulated DC power supply voltage
Connector X1: | Shield is connected to positive voltage supply |
|
Centre is connected to ground (GND)
It is recommended to use 9V to keep the power dissipation to a minimum. Otherwise, an additional heat sink for the linear voltage regulator might be necessary.
7.2Edge connector (J2, J3, J4, J5)
All pins of the microcontroller
Connector | MCU Pins | |

The odd pin numbers are located on the one side and the even pin numbers are located on the other side of the connector.
On the PCB, the corresponding pin numbers of the TC are written next to the connector pins.
7.3GND/VCC (JP11)
Additionally Vcc and GND Pins are placed on the board (JP11).
