Product Description
The L9110S Dual DC / Stepper Motor Driver Board Module is a compact and efficient driver board designed for controlling two DC motors or a single bipolar stepper motor in small robotics and embedded projects. Built around the L9110S H-bridge driver ICs, this module operates at low voltages (typically 2.5 V to 12 V) and provides bidirectional drive control, making it ideal for lightweight robot platforms, toy motors, and hobby stepper applications.
It features simple input control lines that can be interfaced directly with microcontroller GPIO pins for forward, reverse, and speed (via PWM) control. The module is popular in Arduino, ESP32, STM32, Raspberry Pi, and other microcontroller ecosystems for small-scale motion control needs where power requirements are modest.
