3.19.10 Interrupt Switch
Interrupt switch on the microcontroller adapter board is connected to PE7 (INT7) pin of the
microcontroller. It has external 10K pull-up resistor. When switch is pressed, PE7 becomes logic
low. Location of the interrupt switch is shown in figure 3.58.

Important:
Before using interrupt switch, ensure that soldering pad P1 on the main board is open. For more
information refer to figure 3.28 and section 3.9.
3.19.11 Servo Connectors
The microcontroller board has three Servo connectors as shown in figure 3.58. It can be used for
driving servo motors of camera pod or any other attachment. Power for the servo connector is
provided by the "5V servo supply" voltage regulator. Figure 3.73 shows correct orientation of
the servo motor's connector.
