The L9110S dual-channel motor driver module is a compact and reliable solution for driving small DC motors or a single 4-wire, 2-phase stepper motor—perfect for DIY robots and Arduino projects. Built around the L9110 motor driver IC, it features two independent channels, each capable of delivering up to 800 mA continuous current.

With an operating voltage range of 2.5 V to 12 V, this module works seamlessly with both 3.3 V and 5 V microcontrollers. Speed control is achieved via PWM (Pulse Width Modulation), while direction control uses standard digital outputs.

Connections are simple—female header pins link the module to your microcontroller, and screw terminals make motor wiring secure and hassle-free. Four mounting holes make installation easy in your robot or project enclosure.

Features:

• Dual-channel H-bridge driver for two DC motors or one stepper motor'
• Simple PWM speed and digital direction control
• Compact size with 4 mounting holes for easy integration.
• Suitable with both TTL and CMOS output levels, direct CPU connection is possible.
• The IC integrates control and drive.

• Motor Channels: 2
• Driver IC: L9110S (Dual H-Bridge)
• Size: 29 x 21 mm (L x W)
• Working Range: 0 to 80 degrees Celsius

Frequently Asked Questions;

1) What can a dual H-bridge motor driver provide?

The motor controller breakout board L298N Dual H Bridge Motor Driver is frequently used to regulate the speed and direction of motors. Additionally, it may be used to regulate the brightness of some lighting fixtures, including powerful LED arrays.

2) Can an H-bridge control speed?

3) Do H bridges need diodes?

Unfortunately, a single flyback diode is insufficient when employing an H-bridge circuit. There must be four diodes to provide a channel for the induced voltage because of the various current paths.
