Description
Product Details

The L9110S Two Channel Motor Driver Board (MPN: L9110S) is a miniature dual H-Bridge motor driver module built around two integrated L9110 driver ICs. It enables low-power microcontrollers — including Arduino and Raspberry Pi — to safely control the direction and speed of two independent DC motors or one bipolar stepper motor, without exposing the MCU to the motors' higher current demands.

Key Features

Dual H-Bridge Architecture: Two independent L9110 ICs provide a full H-Bridge per motor channel, enabling forward and reverse direction control on both channels simultaneously.
PWM Speed Control: Applying a PWM signal to the control inputs allows smooth, variable-speed motor control — ideal for line-following robots and adjustable-speed drives.
Direction Control via Digital Logic: Each channel accepts HIGH/LOW logic signals to instantly switch motor direction without additional components.
Stepper Motor Support: The two channels can be combined to drive a single 4-wire bipolar stepper motor, making this module versatile for positioning applications.
No External Heatsink Required: The compact design dissipates heat efficiently under normal operating conditions, keeping your build clean and lightweight.
Ultra-Compact Footprint: Significantly smaller than L298N-based boards, making it the preferred choice for mini robotics, drones, and tight PCB layouts.

Pinout & Wiring

PIN	Symbol	Description
1	B-IA	Motor B Input A — direction/PWM control for Channel B
2	B-IB	Motor B Input B — direction/PWM control for Channel B
3	GND	Common Ground
4	VCC	Motor & Logic Supply Voltage
5	A-IA	Motor A Input A — direction/PWM control for Channel A
6	A-IB	Motor A Input B — direction/PWM control for Channel A
7	MOTOR-B1	Motor B Output terminal 1
8	MOTOR-B2	Motor B Output terminal 2
9	MOTOR-A1	Motor A Output terminal 1
10	MOTOR-A2	Motor A Output terminal 2

Wiring Note: Connect VCC and GND to your power supply, wire the four control inputs (A-IA, A-IB, B-IA, B-IB) directly to digital or PWM-capable GPIO pins on your microcontroller, and connect the motor terminals to your DC motors or stepper motor coils.

Compatibility

Arduino UNO / Nano / Mega: Fully compatible — control pins operate at 5V logic, matching Arduino GPIO output levels directly.
Raspberry Pi / ESP32 / ESP8266: Compatible via 3.3V logic signals; verify motor supply voltage suits your motors.
Any 5V or 3.3V Microcontroller: The L9110 ICs accept a wide logic input range, making the module broadly compatible across platforms.

Typical Applications

Mini Robotics & Line-Following Robots: The most popular use case — drive two DC gear motors independently for differential steering in compact robot chassis.
STEM & Educational Projects: A beginner-friendly module for students learning motor control with Arduino, providing a safe interface between MCU and motor power.
Bipolar Stepper Motor Control: Drive a single 4-wire stepper motor for precise positioning in small CNC, camera sliders, or scanner mechanisms.
RC Vehicles & Drones: Its ultra-low profile and weight make it suitable for weight-sensitive builds where an L298N would be too bulky.
Automated Blinds / Small Actuators: Control low-power linear actuators or gear motors in home automation prototypes.

FAQ

Q: Can the L9110S replace an L298N in my project?
A: Yes, for small DC motors and light stepper applications. The L9110S is much smaller and requires no heatsink, but is intended for lower-power motors than the L298N.

Q: Can I control motor speed with PWM on Arduino?
A: Yes. Connect any PWM-capable Arduino pin (e.g., D3, D5, D6, D9, D10, D11 on UNO) to the control inputs and use analogWrite() to vary motor speed smoothly.
