L9110S DC motor/stepper motor drive board, motor drive board,H bridge motor drive
One-module description

1 Double 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-12V, and the large working current is 0.8A. The voltage and current of the smart car on the market are in this range

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

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

6 Fixed mounting holes, diameter: 3mm
