L9110S DC Stepper Motor Driver Board

The L9110S Dual Channel Motor Driver Module is a compact and versatile board designed for driving small robots. It features two independent L9110S motor driver chips, each capable of driving up to 800mA of continuous current. This module can operate from 2.5V to 12V, making it compatible with both 3.3V and 5V microcontrollers.

The module connects to the microcontroller using male header pins, while the motors are connected via screw terminals. Speed control is achieved using PWM signals, and direction control is done using digital outputs. Additionally, this module can also drive a single four-line two-phase stepper motor. The board has four mounting holes for easy installation on your robot or other projects.
