Control Inputs:

The STBY pin is the enable pin and is active HIGH to enable the motors to operate.  The STBY pin is pulled LOW via a 200K pull-down resistor by default which disables the motors.  To enable the motors to operate, this pin needs to be pulled HIGH.  This can be done either by tying the pin to Vcc or by driving the pin HIGH using an output pin of a uC.

The PWMA/PWMB are PWM inputs for motor speed control.  The PWMA input controls the speed of Motor A and PWMB controls the speed of Motor B.  The higher the PWM value (up to 255) the faster the motor turns.  At low PWM values, there is a point at which the DC motor does not receive enough drive power to cause the motor to turn.  A motor may require a minimum PWM value of 25 or 50 to start turning.  This is best determined experimentally.

The AIN1, AIN2, BIN1 and BIN2 are control pins that determine the configuration of the two H-Bridges in the device.  The AIN1 / AIN2 pins control the ‘A’ motor bridge and the BIN1 / BIN2 pins control the ‘B’ motor bridge.    The H-Bridge is what controls the direction that the motor turns as shown in the chart below.  It can also be used for on/off control of desired.

Note: that the direction that the motors turn (forward vs reverse) with the above commands depends on how the ‘+’ and ‘-‘ leads of  the motors are wired to the module.  If they are turning backwards from what is expected, reverse the motor leads at the module.

Module Connections:
