Compact and efficient
The size is perfect for tight spaces in custom PCB designs. It drove two 6V fans simultaneously without any voltage drop issues. Highly recommended for embedded system prototyping.

Perfect for my fire robot project
This L9110 module worked flawlessly with my Arduino Uno. I used it to control the fans on my fire-extinguishing robot, and the response time is excellent. The wiring was straightforward, and it handles the current without getting too hot.

Reliable motor driver
I've bought three of these now for different smart car chassis. They are very reliable for small DC motors. The dual H-bridge configuration makes controlling direction and speed via PWM very simple.

Solid performer for beginners
We use these in our weekend workshops. Students find them easy to interface with MicroPython on the ESP32. Just ensure you provide adequate cooling if running near max current for extended periods.

Exceeded expectations
Fast shipping and the product arrived well-packaged. Tested it immediately with a 12V fan setup for a ventilation prototype, and it handled the load smoothly. Will buy again.

Good value for learning
Great little board for university projects. It's compact and easy to solder headers onto. One star off because the silk screen printing is a bit faint, but functionally it does exactly what it says.
Q: Is this compatible with 3.3V logic boards like the ESP32?
A: Absolutely. The module operates within a wide voltage range and accepts TTL logic levels, making it fully compatible with both 3.3V and 5V microcontrollers.
Q: Can this module drive a stepper motor?
A: Yes, the L9110S has two H-bridges which can be configured to drive one bipolar stepper motor or two independent DC motors.
Q: What is the maximum voltage input allowed?
A: The maximum operating voltage is 12V. Please do not exceed this limit to avoid damaging the L9110S chip.
Q: Can I use this for a fire extinguishing robot fan control?
A: Yes, this module is specifically suitable for that application. It can efficiently control the DC fans required for blowing out flames in educational robotics competitions.
Q: Does this come with pin headers pre-soldered?
A: No, the module is typically shipped without pre-soldered headers to allow flexibility for direct wire soldering or using custom connectors. You will need to solder them yourself.
