The L9110S dual channel h-bridge motor driver module is a compact board based on the L9110 Motor Driver IC. It features two independent motor driver chips, each capable of driving up to 800mA of continuous current. This module can be powered from 2.5 volts to 12 volts, making it compatible with both 3.3 volts and 5 volts microcontrollers.
A set of female header pins is provided for easy connection to a microcontroller, while the motors can be attached via two sets of screw terminals. The module uses PWM (Pulse Width Modulation) signals to control motor speed and digital outputs to change motor direction. Additionally, it can be used to drive a single four-line two-phase stepper motor.
The board includes interfaces for easy connection:

6P black bent pin description:
- 1. VCC external voltage 2.5V-12V
- 2. GND External GND
- 3. AIA external microcontroller IO port
- 4. AIB external microcontroller IO port
- 5. BIA external microcontroller IO port
- 6. BIB external microcontroller IO port
-
4P green terminal:
- 1. OA1 OB1 contact DC 2-pin, non-directional
- 2. OA2 OB2 contact DC 2-pin, non-directional
For usage, simply power ON VCC and GND to see the module power indicator light up. Control the motor by setting the input signals as follows:
- AIA input high, AIB input low - motor transfer
- AIA input low, AIB input high - motor reversal
- BIA input high, BIB input low - motor transfer
- BIA input low, BIB input high - motor reversal
