Compact yet powerful, the L9110S Dual Channel Motor Driver Module is an essential component for your robotics and smart car projects. Designed to be a more efficient and smaller alternative to the L298N, this H-Bridge driver can simultaneously control two DC motors or one 4-wire 2-phase stepper motor. It is fully compatible with Arduino, microcontrollers, and various DIY electronic kits.

Key Features:

• Dual H-Bridge Design: Capable of driving 2 DC motors or 1 stepper motor independently.
• Wide Voltage Range: Supports motor operating voltages from 2.5V to 12V.
• Current Capacity: Handles a continuous current of 0.8A per channel, suitable for most standard smart car motors.
• Compact Footprint: Ultra-small PCB size (29mm x 23mm) makes it easy to fit into tight enclosures.
• Easy Installation: Equipped with 3mm mounting holes for secure attachment.

Technical Specifications:

• Chip: Dual L9110S
• Supply Voltage: DC 2.5V - 12V
• Max Operating Current: 0.8A per channel
• Dimensions: 29mm x 23mm x 12mm (approx.)
• Interface: TTL / CMOS output level compatible

Pinout & Wiring Guide:

• 6-Pin Header (Control Inputs):
  • VCC: External Voltage (2.5V-12V)
  • GND: External Ground
  • A-1A / A-1B: Microcontroller IO ports for Motor A
  • B-1A / B-1B: Microcontroller IO ports for Motor B
• 4-Pin Screw Terminal (Motor Outputs):
  • Motor A: Connect to DC Motor A (No polarity)
  • Motor B: Connect to DC Motor B (No polarity)

How to Use (Logic Table): Simply connect VCC and GND to power the module (Power LED will light up). Control the direction by sending High/Low signals from your microcontroller:

• Forward: Input A High, Input B Low
• Reverse: Input A Low, Input B High
• Stop/Idle: Both Inputs Low or Both Inputs High
