The L9110S dual-channel h-bridge motor driver module designed as a compact board used to drive small robots. This module based on the L9110 Motor Driver IC. This L9110S dual-channel H-bridge motor driver consists of two independent motor driver chips in which each capable of driving a continuous current up to 800mA. The boards operate at a voltage range from 2.5 V to 12 V enabling this module to used with both 3.3 Volts and 5 Volts microcontrollers. A set of female header pins provided to connect this module to a microcontroller. The motors easily attached via two sets of screw terminals.
The speed of the motor is controlled by a PWM Pulse Width Modulation signal and a digital output is used to change its direction. This module also used to drive a single four-line two-phase stepper motor. This module can be easily mounted onto your robot or other projects via four holes provided on the board.
