Motor Driver 5V/7V/9V Three-Speed Adjustable with Charging Function, Small Fan Drive Module Description

Product Introduction:

This is a small fan driver board. The battery input is a lithium battery with a voltage input of 3.00V-4.20V. It features three speed settings controlled by buttons, with fan outputs of [email protected]. When the load is a typical 9V brushless motor fan, the output is not constant voltage. The no-load output is 16V, suitable for fans of all sizes (9V brushless motor, to 10W).
This output voltage is not constant; it's primarily used to differentiate between three fan speeds in small fans. The output voltage ([email protected]) increases with battery voltage and decreases with battery voltage decrease. The MOSFET is external, allowing it to power sufficiently large fans. Theoretically, it can power a 9V brushless motor to 10W.
It can be used in DIY projects to drive small fans. It can also be connected to a 5V Type-C input without a battery. When a battery is available, it can charge it with a charging current of 0.80A and a cutoff voltage of approximately 4.20V.
