Instructions could be clearer

The module works but the pinout diagram on the back was hard to read. Had to test with a multimeter to confirm input and output pins. Otherwise functional.

Great for mini fire robots

I am building a mini fire-fighting robot and this driver handles the exhaust fans perfectly. Dual channel support is a nice bonus for future expansions.

Good value for money

Small and compact which fits well in my robot chassis. The pins were slightly loose on arrival but soldering fixed it. Functions as described.

Reliable driver module

No heating issues observed during testing. Voltage range is accurate and it interfaces easily with 3.3V logic boards like the ESP32. Very satisfied.

Works perfectly for cooling projects

Used this module to control a small DC fan on my Arduino setup. The PWM control is smooth and the module stays cool even after hours of operation. Highly recommended for hobbyists.

5 FAQ

Q: What is the maximum voltage this module can handle?

A: The L9110 module supports an operating voltage range of DC 2.5V to 12V. Please do not exceed 12V to avoid damage.

Q: Can I drive two fans simultaneously with one module?

A: Yes, this module features dual H-bridge channels, allowing you to control two separate DC motors or fans independently.

Q: Do I need an additional heat sink for this module?

A: For typical hobby applications within the rated current, no additional heat sink is required. The PCB is designed to dissipate heat adequately.

Q: Does it support PWM speed control?

A: Absolutely. You can use PWM signals on the input pins to control the speed of the connected fans or motors precisely.

Q: Is this compatible with 3.3V logic boards like ESP32?

A: Yes, the control interface is TTL compatible and works safely with 3.3V logic systems such as the ESP32 and ESP8266.
