The L9110S dual channel h-bridge motor driver module is a compact board that can be used to drive small robots. This module is based on L9110 Motor Driver IC. This module has two independent motor driver chips which can each drive up 800mA of continuous current. The boards can be operated from 2.5 volt  to 12 Volt enabling this module to be used with both 3.3 Volts and 5 Volts microcontrollers. A set of female header pins is used to connect this module to a micro controller. The motors are attached via two sets of screw terminals.

A PWM Pulse Width Modulation signal is used to control the speed of a motor and a digital output is used to change its direction. This module can also be used to drive a single four line two phase stepper motor. Four holes make this board easy to mount onto your robot or other project.
