L298N with ESP32-S3-DevKitC-1

Wiring for the L298N dual motor driver on the ESP32-S3-DevKitC-1 (ESP32-S3, 3.3 V logic), chosen with the same pin rules BoardPilot uses: default buses first, and no pins that are used for flash, USB, the debugger or booting.

Wiring

L298N pin	Role	ESP32-S3-DevKitC-1 pin	Notes
ENA	Input to the part	4	Motor A speed (PWM). Remove the jumper to use it
IN1	Input to the part	5	Motor A direction
IN2	Input to the part	6	Motor A direction
IN3	Input to the part	7	Motor B direction
IN4	Input to the part	15	Motor B direction
ENB	Input to the part	16	Motor B speed (PWM). Remove the jumper to use it
12V	Not wired to the board	not connected	Motor supply 5 to 35 V from a separate supply
GND	Ground	G
5V	Not wired to the board	not connected	5 V output of the on-board regulator (jumper on, supply up to 12 V)
OUT1	Not wired to the board	not connected	Motor A
OUT2	Not wired to the board	not connected	Motor A
OUT3	Not wired to the board	not connected	Motor B
OUT4	Not wired to the board	not connected	Motor B

Check before you power it on

Motors, servos, relays and LED strips can draw more current than the ESP32-S3-DevKitC-1’s pins or USB can give. Power them separately and connect the grounds together.

Test code (Arduino)

// Motor A: ENA = speed (PWM), IN1/IN2 = direction. Remove the ENA jumper on the module.
void setup() {
  pinMode(5, OUTPUT);
  pinMode(6, OUTPUT);
  pinMode(4, OUTPUT);
}

void loop() {
  digitalWrite(5, HIGH);
  digitalWrite(6, LOW);
  analogWrite(4, 180);  // about 70% speed
  delay(2000);
  analogWrite(4, 0);    // stop
  delay(1000);
}

Arduino board: esp32:esp32:esp32s3. Use the port labelled UART. If uploading does not start, hold BOOT, press and release RESET, then release BOOT.

Questions

Which ESP32-S3-DevKitC-1 pins do I use for the L298N?

ENA → 4, IN1 → 5, IN2 → 6, IN3 → 7, IN4 → 15, ENB → 16, GND → G.

Does the L298N work with the ESP32-S3-DevKitC-1 at 3.3 V?

Yes: the L298N runs at 5 V and the ESP32-S3-DevKitC-1 uses 3.3 V signals, so no level shifting is needed.

BoardPilot checks this wiring in 3D as you build it, and finds crossed or missing wires on the real board.
