Pinout
32| Pin | Name | Functions | Notes |
|---|---|---|---|
| — | GND | GND | |
| — | BAT | POWER | Positive voltage to/from JST connector for optional lipoly battery. |
| — | USB | POWER | Positive voltage to/from USB-C connector if connected. |
| — | EN | GPIOPOWER | 3.3V regulator enable pin. Pulled up, connect to ground to disable. |
| — | 3V | POWER | Output from 3.3V regulator, 500mA peak. Half drawn by ESP32. |
| — | RST | GPIO | Reset pin, tie to ground to reset the board. |
| 35 | VOLTAGE_MONITOR | ADC | ADC pin for battery voltage monitoring (requires multiplication by two). |
| 0 | NEOPIXEL | GPIOPWM | WS2812B compatible RGB LED. |
| 2 | NEOPIXEL_I2C_POWER | GPIOPOWER | Controls power for NeoPixel and STEMMA QT. High for on, low for low-power mode. |
| 13 | LED_BUILTIN | GPIO | On-board red LED. |
| 38 | BUTTON | GPIO | User input button (GPIO38), input-only with pull-up. |
| 26 | A0 | GPIOADCDAC | DAC2, ADC2. ADC2 cannot be used when WiFi is active. |
| 25 | A1 | GPIOADCDAC | DAC1, ADC2. ADC2 cannot be used when WiFi is active. |
| 34 | A2 | GPIOADC | Input/ADC only, ADC1. |
| 39 | A3 | GPIOADC | Input/ADC only, ADC1. |
| 36 | A4 | GPIOADC | Input/ADC only, ADC1. |
| 4 | A5 | GPIOADC | ADC2. ADC2 cannot be used when WiFi is active. |
| 5 | SCK | GPIOSPI | SPI clock. |
| 19 | MOSI | GPIOSPI | SPI Microcontroller Out / Serial In. |
| 21 | MISO | GPIOSPI | SPI Microcontroller In / Serial Out. |
| 7 | RX | GPIOUART | UART receive (Serial1). |
| 8 | TX | GPIOUART | UART transmit (Serial1). |
| 37 | D37 | GPIOADC | Input/ADC only, ADC1. Corner pin next to TX. |
| 13 | D13 | GPIOADC | ADC2. ADC2 cannot be used when WiFi is active. |
| 12 | D12 | GPIOADC | ADC2. ADC2 cannot be used when WiFi is active. Boot strapping pin, must be low on power-on/reset. |
| 27 | D27 | GPIOADC | ADC2. ADC2 cannot be used when WiFi is active. |
| 33 | D33 | GPIOADC | ADC1. |
| 15 | D15 | GPIOADC | ADC2. ADC2 cannot be used when WiFi is active. May have PWM output during boot. |
| 32 | D32 | GPIOADC | ADC1. |
| 14 | D14 | GPIOADC | ADC2. ADC2 cannot be used when WiFi is active. May have PWM output during boot. Can be I2C SCL for MicroPython. |
| 20 | SCL | GPIOI2C | I2C clock. Not supported for I2C in MicroPython (use pin 14). |
| 22 | SDA | GPIOI2C | I2C data. |
