L9110S Stepper Motor Driver Module is a simple, low-cost DC motor and small stepper motor driver board based on the L9110S dual H-bridge motor driver IC. It’s widely used in hobby electronics and microcontroller projects (like Arduino, Raspberry Pi, ESP32, PIC, etc.) to control the direction and speed of small motors.
