There are 8 analog input pins on the Nano ESP32, with 2 reserved for I2C communication (A4/A5). The ESP32-S3 embeds two SAR ADCs, `ADC1` and `ADC2`, where each ADC uses 4 channels each.

The default resolution for the ADC pins are 12-bit (returns a value between 0-4095).

| Pin | Type | Function | ADC channel |
| --- | ------ | ------------------------------------------- | ----------- |
| A0 | Analog | Analog input 0 | `ADC1_CH0` |
