Reliable motor driver

I've tested this with several small DC motors and fans. The L9110 chip provides smooth speed control via PWM. Highly recommended for beginners starting with robotics.

Perfect for my firefighting robot project

This module works exactly as described. I used it to control the cooling fans on my custom microcontroller board, and the response time is excellent. The pinout is clearly labeled, making wiring very easy.

Good value for money

Solid build quality for the price. It handles the current well without getting too hot. I deducted one star because the included header pins were slightly bent, but that was an easy fix.

5 FAQ

Q: Can this module drive two fans simultaneously?

A: Yes, the L9110 has dual H-bridge channels, allowing you to control two separate DC motors or fans independently at the same time.

Q: Can I use PWM to control the fan speed?

A: Yes, you can use Pulse Width Modulation (PWM) signals on the input pins to precisely control the speed of the connected fans or motors.

Q: What is the maximum temperature this module can withstand?

A: The operating temperature range is typically -20°C to +85°C. For high-load applications, we recommend ensuring adequate airflow to keep the chip cool.

Q: Does the package come with screws for mounting?

A: No, the package includes the module and pin headers only. However, the board has standard mounting holes that accept M3 screws, which are sold separately.

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 3.3V and 5V microcontrollers.
