Pins and ESP32 wiring
| Pin | Role | ESP32 pin | Notes |
|---|---|---|---|
| A+ | Not wired to the ESP32 | — | Coil A. Wire colours vary: find the pairs with a multimeter |
| A- | Not wired to the ESP32 | — | Coil A |
| B+ | Not wired to the ESP32 | — | Coil B |
| B- | Not wired to the ESP32 | — | Coil B. Never connect the motor to the ESP32 directly: use a driver |
Suggested wiring for the 30-pin ESP32 DevKit, avoiding flash, input-only and strapping pins. BoardPilot checks it for you as you wire.
This module is sold for 5 V. Its outputs may be 5 V: use a level shifter or a voltage divider on ESP32 inputs.
