Description:
Compact L9110 dual H-bridge module drives two DC motors or one 4-wire stepper. 2.5–12 V input, up to 800 mA per channel. Ideal for hobby robotics & embedded systems.
The L9110 Motor Driver Module is a compact, efficient dual H-bridge driver designed for small motors and stepper applications. It allows you to drive two DC motors or one 4-wire (2-phase) stepper motor with ease, all at currents up to 800 mA per channel under typical operating conditions.
This module works in a wide voltage range (2.5 V to 12 V), making it well suited to both 3.3 V and 5 V microcontroller systems. With its simple input interface and onboard protection, it’s a popular choice for makers, robotics, IoT devices, and DIY motion control projects.
