The L9110 module is a two-way or dual-channel H-bridge motor controller or driver module with a small footprint. The module has two L9110 ICs, each of which can operate one stepper motor or two DC motors individually. It supports a wide range of voltages from 2.5 to 12 volts, making it compatible with both 3.3V and 5V microcontrollers. Both motor controller chips can drive a continuous current of up to 800mA. To prevent any damage to devices like microcontrollers, the module includes an output clamp diode. The module is suitable to control small robot cars. It contains a set of header pins for connecting to a microcontroller and a pair of two screw terminals for connecting to motors. With a PWM (pulse width modulation) signal and digital output, the motor's speed can be easily controlled.
