ESP32 Drone Wiring Diagram: MOSFET Motor Pins

Here is the full schematic circuit. Each motor channel is the same: battery + → motor → MOSFET → GND, with the ESP32 pin controlling the gate. The MPU6050 talks to the ESP32 over I²C (SDA on GPIO 21, SCL on GPIO 22).

Parts and connections

GPIO 25

→ Q1 → front-left motor

GPIO 26

→ Q2 → front-right motor

GPIO 27

→ Q3 → rear-left motor

GPIO 14

→ Q4 → rear-right motor

GPIO 21

→ MPU6050 SDA

GPIO 22

→ MPU6050 SCL

Check before the next step

• All GNDs connected together
• No bare wires touching
• Check with a multimeter before connecting the battery
