Method 1:

• VCC pick MCU 5V power supply, GND connected microcontroller GND
• R_EN and L_EN shorted and connected to 5 level, the drive to work.
• L_PWM, input PWM signal or high motor forward
• R_PWM, input PWM signal or high motor reversal

Method 2:

• VCC pick MCU 5V power supply, GND connected microcontroller GND
• R_EN and L_EN short circuit and PWM signal input connected to high-speed
• L_PWM, pin input 5V level motor is transferred
• R_PWM, pin input 5V level motor reversal

Example

#include <TomIBT2.h>

#define MOTOR_PIN_R_EN        7
#define MOTOR_PIN_L_EN        8
#define MOTOR_PIN_RPWM        10  // PWM 490.20Hz
#define MOTOR_PIN_LPWM        9   // PWM 490.20Hz

TomIBT2 motor(MOTOR_PIN_R_EN, MOTOR_PIN_L_EN, MOTOR_PIN_RPWM, MOTOR_PIN_LPWM);

void setup() {
  motor.begin();
}

void loop() {
    rotateMotor(255, TomIBT2::CW, 2000);
}

void rotateMotor(int speed, TomIBT2::Direction direction, long rampTimeMs = 1000) {
  motor.setTargetSpeed(speed);
  motor.rampUp(direction, rampTimeMs);
}
