The HG7881 (L9110S) Dual Channel Motor Driver Module is a compact board that can be used to drive  DC motors. This module has two independent HG7881 (L9110S) motor driver chips which can each drive up 800mA of continuous current. The boards can be operated from 2.5V to 12V enabling this module to be used with both 3.3V and 5V microcontrollers. A set of male header pins is used to connect this module to your microcontroller I/O pins. 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.
