BoardPilotL9110S dual motor driver with ESP32
Supply 5 V
Bus GPIO
Pins and ESP32 wiring
| Pin | Role | ESP32 pin | Notes |
|---|---|---|---|
| B-IA | Input (the ESP32 drives it) | D25 | Motor B input A (PWM) |
| B-IB | Input (the ESP32 drives it) | D26 | Motor B input B (direction) |
| GND | Ground | GND | |
| VCC | Power | VIN | 2.5 to 12 V, also feeds the motors. Use a separate supply for anything but tiny motors |
| A-IA | Input (the ESP32 drives it) | D27 | Motor A input A (PWM) |
| A-IB | Input (the ESP32 drives it) | D32 | Motor A input B (direction) |
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.
