Pinout
27| Pin | Name | Functions | Notes |
|---|---|---|---|
| GND | GND | POWER | Common ground for all power and logic. |
| BAT | BAT | POWER | Positive voltage to/from the JST connector for the optional lipoly battery. |
| USB | USB | POWER | Positive voltage to/from the USB-C connector if connected. |
| EN | EN | POWER | 3.3V regulator's enable pin, pulled up and connect to ground to disable the 3.3V regulator. |
| 3V | 3V | POWER | Output from the 3.3V regulator, can supply 500mA peak but half is drawn by the ESP32. |
| RST | RST | GPIO | Reset pin used for reset button and standalone use. |
| A0 | A0 | ADC | Also DAC2, ADC2 input. |
| A1 | A1 | ADC | Also DAC1, ADC2 input. |
| A2 | A2 | ADC | Pin 34, ADC1 input only. |
| A3 | A3 | ADC | Pin 39, ADC1 input only. |
| A4 | A4 | ADC | Pin 36, ADC1 input only. |
| A5 | A5 | ADC | Pin 4, ADC2. |
| SCK | SCK | SPI | SPI clock pin, also pin 5. |
| MO | MO | SPI | SPI Microcontroller Out / Serial In (MOSI), also pin 19. |
| MI | MI | SPI | SPI Microcontroller In / Serial Out (MISO), also pin 21. |
| RX | RX | UART | UART RX, also pin 7. Separate from the 'debug UART' connected to USB-to-Serial converter. |
| TX | TX | UART | UART TX, also pin 8. Separate from the 'debug UART' connected to USB-to-Serial converter. |
| D37 | D37 | GPIO | Input/ADC only, ADC1, also pin I37. |
| D13 | D13 | ADC | Pin 13, ADC2. Also a special 'boot strapping' pin on the ESP32. |
| D12 | D12 | ADC | Pin 12, ADC2. |
| D27 | D27 | ADC | Pin 27, ADC2. |
| D33 | D33 | ADC | Pin 33, ADC1. |
| D15 | D15 | GPIO | Pin 15, ADC2. May have some PWM signal output during boot but can be used as desired. |
| D32 | D32 | ADC | Pin 32, ADC1. |
| D14 | D14 | GPIO | Pin 14, ADC2. May have some PWM signal output during boot but can be used as desired. |
| SCL | SCL | I2C | I2C clock pin, also pin 20. |
| SDA | SDA | I2C | I2C data pin, also pin 22. |
