This module built arround L9110 chip which has two TTL / CMOS compatible with the level of the input, with good resistance. Two output terminals can directly forward and reverse movement of the drive motor. It has a large current driving capability, each channel through 750 ~ 800mA of continuous current, peak current capability up to 1.5 ~ 2.0A, while it has a low output saturation voltage. Built-in clamp diode reverse the impact of the current release inductive load it in the drive relays, DC motors, stepper motor or switch power tube use on safe and reliable. L9110 is widely used in toy car motor drives, stepper motor drive and switching power tube circuit. L9110 Fan Motor Module is highly efficient and can easily blow out the lighter flame which is 20 cm away and can be used for designing fire fighting robots.
Working Voltage: 5V
Propeller diameter: 75mm
