Figure 18. Potentiometer circuit
NOTE
To measure the POT value, program the ADC in differential mode.
The V_BATT is taken as the differential input.

IR transmitter (CMT interface)
An infrared transmitter or blaster is provided to control the IR. Figure 19 shows the IR circuit.
•
The IR power supply is P3V3_LED.
•
The IR has a range of approximately 10 meters.
•
The current draw is approximately 100 mA when active.
•
When using the blaster as an application, assure the proper orientation.
