1. L9110S-chip motor drive 2. Module supply voltage: 2.5-12V 3. Suitable motor range: operating voltage between 2.5V-12V, maximum operating current 0.8A; compatible with most smart car motors on the market 4. Drives two DC motors or a 4-wire 2-phase stepper motor 5. PCB board size: 2.8cm x 2.1cm, compact design for easy integration; includes mounting holes with 3mm diameter 6. Module interface: 6P black header pins: VCC – connect to external 2.5V-12V power GND – connect to external ground IA1 – connect to microcontroller IO pin IB1 – connect to microcontroller IO pin IA2 – connect to microcontroller IO pin IB2 – connect to microcontroller IO pin 4P green terminal blocks: OA1, OB1 – connect to two terminals of DC motor (direction not fixed) OA2, OB2 – connect to two terminals of DC motor (direction not fixed) 7. Module operation: When VCC and GND are powered, the module indicator light turns on IA1 high, IB1 low – motor connected to OA1/OB1 runs forward IA1 low, IB1 high – motor connected to OA1/OB1 runs in reverse IA2 high, IB2 low – motor connected to OA2/OB2 runs forward IA2 low, IB2 high – motor connected to OA2/OB2 runs in reverse 8. Note: Basic electronic knowledge and hands-on experience are required for installation. Purchase with care.
