Motor Driver (L9110S) Internal Supply

Motor Driver (L9110S) Internal Supply

AX22-0037

Need to spin one DC motor forward, reverse, coast, or brake without burning GPIOs? This AX22 board does it neatly. The power in this module is provided through Vin pins Two active-high control pins (IN1, IN2) give simple direction and PWM speed control. Power can come from the AX22 backplane’s power rail or a separate external VExt Input, just move a solder jumper to select. Snap it into an AX22 backplane and drive wheels, sliders, or pumps in minutes with Arduino IDE, MicroPython, or MicroBlocks.

Arduino Example Snippet 

#define MOTOR_A1 14
#define MOTOR_A2 41

#define SPEED 200   // PWM value (0-255)

void setup() {
  pinMode(MOTOR_A1, OUTPUT);
  pinMode(MOTOR_A2, OUTPUT);
}

void loop() {
  // Forward
  analogWrite(MOTOR_A1, SPEED);
  digitalWrite(MOTOR_A2, LOW);
  delay(2000);

  // Stop
  digitalWrite(MOTOR_A1, LOW);
  digitalWrite(MOTOR_A2, LOW);
  delay(500);

  // Backward
  digitalWrite(MOTOR_A1, LOW);
  analogWrite(MOTOR_A2, SPEED);
  delay(2000);

  // Stop
  digitalWrite(MOTOR_A1, LOW);
  digitalWrite(MOTOR_A2, LOW);
  delay(500);
