Crazybee F4 Pro


The Crazybee F4 Pro Flightcontroller is a redesign of a common F4 FC. There are different models with an embedded as the radio receiver, and 4in1 ESC are all integrated into one single board. The Crazybee F4 Pro has embedded ESC to drive 4x brushless motors as found on small raceingquadcopters like the


PH2.0 battery connector


The Flightcontroller exists in four different PCB variations

  • CrazyBeeF4FRPro for use with Frsky
  • CrazyBeeF4DXPro for use with Spektrum
  • CrazyBeeF4Pro Without receiver
  • CrazyBeeF4FSPro with Nordic chip for Flysky


There are different versions of almost the same board V1,V2, V2.1 and V3. The differences in the table below:


Spiking power on the board when plugging in a 2s battery could lead to a broken board on the original design. To preven this from happening as add a capacitor to the battery lead. This capacitor should have an ESR lower than 0.2ohm and have a capacitance of 100uF or higher. A Rubycon ZLG/ZLH series and Samyoung NXB series.
