Supply 4.5-12 V
Bus GPIO
Pins and ESP32 wiring
| Pin | Role | ESP32 pin | Notes |
|---|---|---|---|
| VIN | Not wired to the ESP32 | — | Pin order varies between boards: match by the printed label. Input 4.5 to 12 V (about 1.1 V more than 3.3 V is needed) |
| GND | Ground | GND | |
| VOUT | Not wired to the ESP32 | — | 3.3 V out, up to about 800 mA. Gets hot at high input voltage |
Suggested wiring for the 30-pin ESP32 DevKit, avoiding flash, input-only and strapping pins. BoardPilot checks it for you as you wire.
