L9110S DC motor/stepper motor driver board, motor driver board, H-bridge motor drive

L9110S DC motor/stepper motor driver board, motor driver board, H-bridge motor drive

One module description

1 Dual L9110S chip motor drive

2 module power supply voltage: 2.5-12V

3 Suitable motor range: the working voltage of the motor is between 2.5V and 12V, and the large working current is 0.8A. The voltage and current of the smart car on the market are within this range

4 can drive 2 DC motors at the same time, or1 4-wire 2-phase stepper motor.

5 PCB board size: 2.8cm * 2.1cm ultra-small size, suitable for assembly

6 with fixed mounting holes, diameter: 3mm
