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

A module description

1 Motor driver of dual L9110S chips

2 Module supply voltage: 2.5-12V

3 Suitable motor range: the motor operating voltage is between 2.5v-12V, and the maximum operating current is 0.8A. The current smart car voltage and current on the market are within this range

4 Can drive 2 DC motors at the same time, or 1 4-wire 2-phase stepping motor.

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

6 With fixed mounting holes, diameter: 3mm
