L9110 L9110S DC Stepper Motor Driver Board HBridge

The L9110S dual-channel h-bridge motor driver module is based on the L9110 Motor Driver IC and has two independent motor driver chips capable of driving up to 800mA of continuous current. It uses PWM signals to control motor speed and digital outputs to change direction. This module can also drive a single four-line two-phase stepper motor.
