## Overview

The FrSky R9 SX Enhanced receiver leverages the ACCESS protocol and OTA support to deliver reliable, low-latency control over 900MHz/868MHz frequencies. Featuring 6 PWM channels with configurable outputs, dual antennas for signal redundancy, and a rugged yet lightweight design, it’s engineered for professional-grade long-range RC applications compatible with R9M Lite series transmitters.

## Description

The R9 SX is the enhanced version of the R9 Slim series of long-range capable receivers. It adds 3-pin servo connectors with 6 full PWM channels and utilizes the dual-antenna design. The light-weight protective shell has a Multi-use 6-pin plug to bring you additional functions like signal redundancy, telemetry feedback, external battery detection and more. Flexibility is a key feature of this receiver. The 6 PWM channels can be converted to 4 PWM channels with the additional Ch5 and Ch6 can be configured as an alternative S.Port and SBUS outputs to the 6-pin port. The enhanced design proves to be more durable, and in conjunction with the latest ACCESS firmware, the two are now synchronized and we are able to unlock the true potential of the ACCESS protocol.
