| PIN | FUNCTION |
|---|---|
| GND | Ground pin |
| Power | VBUS(microUSB voltage), VSYS(2-5VDC input voltage), 3V3(3.3V output voltage) 3V3_EN(Enables Pico) |
| System Control | run (enable or disable the RP2040 microcontroller or reset) |
| ADC | Raspberry Pi Pico has a total of 5 ADCs with a resolution of 12 bits, namely ADC0 (GP26), ADC1 (GP27), ADC2 (GP28), ADC3 (GP29), ADC4. Among them, ADC3 (GP29) is used to measure VSYS on the Pico board; ADC4 is directly connected to the built-in temperature sensor of RP2040. ADC_VREF can be connected to an external accurate voltmeter as ADC reference. The ADC_GND pin serves as the ground reference. |
