L9110S Dual H-Bridge DC Stepper Motor Driver Module 2-Channel 800mA

The L9110S dual H-bridge motor driver module is a compact two-channel board built for controlling small DC motors and four-wire two-phase stepper motors in robotics, automation, and microcontroller-based motion projects. Each channel delivers up to 800mA of continuous output current and operates from a 2.5V to 12V supply, making the module compatible with both 3.3V and 5V logic systems. The board integrates two independent L9110S driver chips, provides TTL/CMOS-compatible inputs for direct connection to microcontroller I/O pins, and includes built-in high-voltage and short-circuit protection. Motor speed is adjusted via PWM signals, while direction is set by logic levels on the input pins. A single four-wire two-phase stepper motor can also be driven using the same two channels. With a board size of approximately 28mm by 21mm, mounting holes of 3mm diameter, and an operating temperature range of 0°C to 80°C, this module suits space-constrained electronic and robotic assemblies.
