Features:

  • Quad L9110S Chips: Drives 4 DC motors or 2 4-wire 2-phase stepping motors.
  • Wide Voltage Range: 2.5V to 12V supply compatibility.
  • High Current Handling: Up to 0.8A continuous working current.
  • Module Interface: A1, A2, B1, B2, C1, C2, D1, and D2 for MCU control.
  • PCB Terminal Block: Connections for MOTOR A, B, C, and D.

Principle of Work:

Each L9110S chip is a dual H-bridge motor driver, allowing control over motor direction and speed. Inputs from a microcontroller control the H-bridges through logic signals, determining motor behavior.

const int A1 = 2;
const int A2 = 3;

void setup() {
  pinMode(A1, OUTPUT);
  pinMode(A2, OUTPUT);
}

void loop() {
  motorForward();
  delay(2000);
  motorStop();
  delay(1000);
  motorReverse();
  delay(2000);
  motorStop();
  delay(1000);
}

void motorForward() {
  digitalWrite(A1, HIGH);
  digitalWrite(A2, LOW);
}

void motorReverse() {
  digitalWrite(A1, LOW);
  digitalWrite(A2, HIGH);
}

void motorStop() {
  digitalWrite(A1, LOW);
  digitalWrite(A2, LOW);
}
