L9110S four-way Drive DC motor driver Board Module 4WD Smart Car

Module description

1 The motor drive module itself is equipped with a four-way L9110S chip.

Power supply voltage of 2 modules: 2.5-12V

3. Suitable motor range: motor working voltage is between 2.5V-12V and maximum working current is 0.8A. The current voltage and current of smart car in the market are all within this range

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