Description
This is a very compact dual channel H-bridge motor driver module. The module incorporates two L9110S H-bridge driver IC’s to allow either one Stepper Motor or two DC Motors to be independently controlled each drive up 800mA of continuous current. The motors are attached via two sets of screw terminals.
The module can accept a supply voltage between 2.5 to 12V allowing for motors within this supply. The voltage range enables this module to be used with both 3.3V and 5V microcontrollers, perfect to be used with an Arduino and robot chassis. A set of female header pins is used to connect this module to a microcontroller.
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. PCB Size: 29.2mm x 23mm
