Datasheet

your microcontroller. E.g. for Arduinos, 5V is probably what you want. Can be 2.7V to

5.5V so good for 3V or 5V logic

GND - This is the shared logic and motor ground. All grounds are connected

Signal in Pins

These are all 'Vcc logic level' inputs

INA1, INA2 - these are the two inputs to the Motor A H-bridges

PWMA - this is the PWM input for the Motor A H-bridges, if you dont need PWM

control, connect this to logic high.

INB1, INB2 - these are the two inputs to the Motor B H-bridges

PWMB - this is the PWM input for the Motor B H-bridges, if you dont need PWM

control, connect this to logic high.

STBY - this is the standby pin for quickly disabling both motors, pulled up to Vcc thru

a 10K resistor. Connect to ground to disable.

Motor Out Pins

These are 'Vmotor level' power outputs

Motor A - these are the two outputs for motor A, controlled by INA1, INA2 and PWMA

Motor B - these are the two outputs for motor B, controlled by INB1, INB2 and PWMB
