## Description

Dual H-bridge module for direction and speed control, ideal for two DC motors or one stepper motor, compatible with Arduino and other development boards. It uses the L9110S driver, operates at 2.5-12V, supports up to 0.8A per channel, has 6 pins for quick connection and compact 28 x 21 mm PCB with 3 mm mounting holes.
The H-bridge with L9110S motor driver is a compact and efficient module, compatible with Arduino and other development boards, designed for controlling two DC motors or one stepper motor. It allows control of direction and speed for up to 2 DC motors, making it a practical choice for robotics, automation, and electronic prototyping projects.
It operates at voltages between 2.5V and 12V and can deliver a maximum current of up to 0.8A, making it suitable for small and medium-sized motors. The small board format and the 6 connection pins allow easy integration into compact assemblies, and the 3 mm mounting holes help securely fix the module in the project.
