The FETtec FC G4 features the latest STM32G473 processor. Providing unparalleled processing power to your aircraft. Along with an IIM-42652 SPI gyro, two 5v BECs, 6-27V (2-6S) power handling, and a host of other features, the G4 from FETtec is on the cutting edge of Flight Controller technology.

 What does "N" version mean?

This product has no onboard analog OSD.

Except for the removed analog OSD, there are no restrictions and you can use the full potential of our fc as you are used to.
Use with other OSDs/ digital FPV systems is still possible as usual.
