Original products only
The L9110S Motor Driver Arduino is a control board designed to drive two DC motors simultaneously or one 2-phase, 4-wire stepper motor. This controller is compatible with Arduino and other microcontroller-based systems, making motor control easier in electronics and robotics projects.
This module features two integrated L9110S motor control chips on a compact PCB, measuring 29.2 mm x 23 mm, making it ideal for applications where space is limited.
Main features
- Input voltage: DC 2.5-12V, suitable for a wide range of power supplies.
- Output capacity: each channel can supply up to 800 mA continuous current, allowing control of small to medium-sized motors.
- Low static working current, optimising power consumption.
- Low saturation voltage drop for better performance.
- Compatible with TTL/CMOS output levels, allowing direct connection to a CPU or microcontroller.
- Includes clamp diodes for protection against inductive loads.
- Integrated IC control unit for greater reliability and ease of use.
- High-pressure protection function via pin.
- Operating temperature: 0-80 °C, suitable for common lab and development environments.
Typical uses
This controller is ideal for robotics, automation and general motor control projects. It can be used to:
- Control two DC motors independently.
- Drive bipolar 2-phase, 4-wire stepper motors.
- Arduino projects that require motor speed and direction control.
Compatibility
The L9110S is compatible with Arduino boards and other microcontrollers that support TTL/CMOS levels. Its design allows easy integration into electronics and robotics projects that require dual motor control or stepper motors.

Customer Questions & Answers
What are the exact dimensions of the board and what is included in the package when buying this controller?
The board measures 29.2 mm x 23 mm. The package includes only the controller board; cables, motors and other accessories are not included.
What should be considered regarding heat dissipation and continuous use near maximum current?
When operating close to 800 mA per channel, it is advisable to ensure passive cooling and avoid prolonged use at full load, as the board has no heatsink and overheating can reduce the component’s service life.
How does the L9110S compare with other drivers such as the L298N in terms of size, efficiency and overcurrent tolerance?
The L9110S is more compact and has a lower voltage drop (low saturation), but it supports less current and lacks robust overcurrent protection. The L298N allows higher currents (~2 A per channel) and supports large inductive loads, but it is bulkier and less efficient.
What type of motors can I control with the L9110S?
You can control two DC motors or one 2-phase, 4-wire stepper motor with this controller.
What is the input voltage range for this controller?
The input voltage range is 2.5 to 12 volts DC.
Is it compatible with Arduino?
Yes, the controller is compatible with Arduino and other microcontrollers that support TTL/CMOS output levels.
What is the maximum current each channel can handle?
Each channel can supply a maximum continuous current of 800 mA.
Does it include protection to prevent damage to the controller?
Yes, it includes high-pressure protection via a pin and clamp diodes for inductive loads.
