The S.Port (Smart Port) is a signal wire full duplex digital transmission interface provided by FrSky Electronic Co., Ltd.

S.Port makes RC components/device setup much easier than conventional multi-wire looms. Any S.Port enabled devices (sensors, sound module, display module, user data interface that in line with FrSky S.Port protocol etc.) can be plug in optionally directly.

With high data transfer speed (6 times more than conventional “hub system”), S.Port offers the superior ability with new high precision hubless sensor and other dataset: smaller, easier, and faster.
