L9110 Motor Dual-Channel H-Bridge Driver Module 12V 800Ma Arduino Compatible

L9110S Motor Driver Module Instructions

1、Module Description

- Motor driver with dual L9110S chips

- Module power supply voltage: 2.5-12V

- Suitable motor range: Motors with operating voltage between 2.5V-12V and maximum operating current of 0.8A; the voltage and current of most smart cars on the market fall within this range

- Can drive 2 DC motors simultaneously, or 1 4-wire 2-phase stepper motor

- PCB board size: 2.8cm×2.1cm, ultra-small size, suitable for assembly

- Equipped with fixed mounting holes, diameter: 3mm

2、Module Interface Description

【6P Black Bent Pin Header Description】

- VCC: External 2.5V-12V voltage input

- GND: External ground connection

- IA1: External MCU (Microcontroller Unit) IO port

- IB1: External MCU IO port

- IA2: External MCU IO port

- IB2: External MCU IO port

【4P Green Terminal Description】

- OA1, OB1: Connect to the two pins of a DC motor (no direction requirement)

- OA2, OB2: Connect to the two pins of a DC motor (no direction requirement)

3、Module Usage Instructions

- Connect VCC and GND; the module power indicator will light up

- Motor control logic:

- For [OA1, OB1] motor: Input high level to IA1 and low level to IB1 → Motor rotates forward; Input low level to IA1 and high level to IB1 → Motor rotates backward

- For [OA2, OB2] motor: Input high level to IA2 and low level to IB2 → Motor rotates forward; Input low level to IA2 and high level to IB2 → Motor rotates backward
