The TB6612FNG motor driver can control up to two DC motors at a constant current of 1.2A (3.2A peak). Two input signals (IN1 and IN2) can be used to control the motor in one of four function modes - CW, CCW, short-brake, and stop. The two motor outputs (A and B) can be separately controlled, the speed of each motor is controlled via a PWM input signal with a frequency up to 100kHz. The STBY pin should be pulled high to take the motor out of standby mode.
Logic supply voltage (VCC) can be in the range of 2.7-5.5VDC, while the motor supply (VM) is limited to a maximum voltage of 15VDC. The output current is rated up to 1.2A per channel (or up to 3.2A for a short, single pulse).
  • Power supply voltage: VM=15V max, VCC=2.7-5.5V
  • Output current: Iout=1.2A(average) / 3.2A (peak)
  • Standby control to save power
  • CW/CCW/short brake/stop motor control modes
  • Built-in thermal shutdown circuit and low voltage detecting circuit
  • Filtering capacitors on both supply lines
Sample code:
/motor A connected between A01 and A02
//motor B connected between B01 and B02
int STBY = 10; //standby
//Motor A
int PWMA = 3; //Speed control
int AIN1 = 9; //Direction
int AIN2 = 8; //Direction
//Motor B
int PWMB = 5; //Speed control
int BIN1 = 11; //Direction
int BIN2 = 12; //Direction
void setup(){
pinMode(STBY, OUTPUT);
pinMode(PWMA, OUTPUT);
pinMode(AIN1, OUTPUT);
pinMode(AIN2, OUTPUT);
pinMode(PWMB, OUTPUT);
pinMode(BIN1, OUTPUT);
pinMode(BIN2, OUTPUT);
void loop(){
move(1, 255, 1); //motor 1, full speed, left
move(2, 255, 1); //motor 2, full speed, left
delay(1000); //go for 1 second
stop(); //stop
delay(250); //hold for 250ms until move again
move(1, 128, 0); //motor 1, half speed, right
move(2, 128, 0); //motor 2, half speed, right
void move(int motor, int speed, int direction){
//Move specific motor at speed and direction
//motor: 0 for B 1 for A
//speed: 0 is off, and 255 is full speed
//direction: 0 clockwise, 1 counter-clockwise
digitalWrite(STBY, HIGH); //disable standby
boolean inPin1 = LOW;
boolean inPin2 = HIGH;
if(direction == 1){
inPin1 = HIGH;
inPin2 = LOW;
if(motor == 1){
digitalWrite(AIN1, inPin1);
digitalWrite(AIN2, inPin2);
analogWrite(PWMA, speed);
digitalWrite(BIN1, inPin1);
digitalWrite(BIN2, inPin2);
analogWrite(PWMB, speed);
void stop(){
//enable standby
digitalWrite(STBY, LOW);
