Figure 3-4. PIC32MK MCM Control Board Buttons, LEDs, and Potentiometers
  • SW4 reset button: The reset button is used to reset the MCU.
  • SW1, SW2, and SW3 user-defined buttons: There are three user-defined buttons, which are connected with GPIO pins to the MCU.
  • D4, D5, and D6 user-defined LEDs: There are three user-defined LEDs, which are driven by the GPIO pins of the MCU.
  • POT1, POT2, and POT3 user-defined potentiometers: There are three user-defined potentiometers, whose output voltages are transmitted to the ADC pins of the MCU.
  • D1, D2, D3, and LEDs to indicate 12V, 3.3V, and 5V: D1, D2, and D3 indicate the voltage source of 12V, 3.3V, 5V respectively.
