FrSky FPort

With F.PORT both channel transmission and telemetry data are carried in a single wire. This makes wiring much easier and additionally, transmission is faster due to improved protocol design.

The most old and new FrSky receivers have support for F.PORT protocol.

Channel transmission, telemetry and integration at the same time.

FrSky F.Port is supported by all Spirit units, except Spirit 1. Spirit GT does not require any special cable. Other units will require the FrSky integration cable that can be bought in our Spirit eshop.
