URUAV FPV Goggles Fan Hub Speed Controller Module for HD3 HDO Goggles

The fan control board of Fatshark can not be switched at will, and will be automatically turned off at regular intervals (the key timing is realized by capacitor discharge, and is not accurate). 
This Fan speed controller module can be replaced perfectly, and realizes functions such as switching and speed regulation.

Note: It is a soft-switch microcontroller design, there is 3-5ma quiescent current after turning off the fan.
          Please remove the after using to prevent over-discharge of the .
