This mini module with integrated L9110 motor driver on its own is a beautifully designed module that you can use while performing simple motor control applications.
The mini prop at the end of the product can also be used as a fan.
There are 4 pins on the card which are Vcc, GND, INA and INB pins. The Vcc connection is 5V and is the supply voltage of the card and the motor. GND is the ground connection. The INA and INB pins are the motor direction pins. The motor direction can be changed by selecting between them.
Arduino, Raspberry Pi, or other applications with microcontrollers can be used with ease. However, you can use your powerful fan in fire-extinguishing robot projects.
