This mini module with its integrated L9110 motor driver is a beautifully designed module that you can use for simple motor control applications.
The mini propeller fan connected to the end of the motor can also be used as a fan.
There are 4 pins on the board:
Vcc: This is the supply voltage for both the board and the motor, which should be 5V.
GND: This is the ground connection.
INA and INB: These pins control the direction of the motor. You can choose between them to change the motor's direction.
It can be easily used with Arduino, Raspberry Pi, or other microcontrollers for various applications. Additionally, you can use its powerful fan in firefighting robot projects.
