L9110S H Bridge Stepper Motor Dual DC Driver Controller Module For Arduino 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 to 800mA of continuous current. The boards can be operated from 2.5 volts to 12 Volts enabling this module to be used with both 3.3 Volts and 5 Volts microcontrollers. A set of female header pins and jumper wires are used to connect this module to a microcontroller like Arduino . 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 projects. This dual-motor driver comes in a compact form factor and it is ideal for use in small robots. The actual direction of “forward” and “reverse” depends on how the motors are mounted and wired. You can always change the direction of a motor by reversing its wiring. The HG7881 (L9110) Dual Channel Motor Driver Module uses two of these motor driver chips. Each driver chip is intended to drive one motor, so having two means that this module can control two motors independently. Each motor channel uses the same truth table as above. Each set of screw terminals is used to connect a motor. Refer to the table below for pin header connections.
