Its durable, lightweight design includes dual antennas for signal redundancy and supports over-the-air firmware updates, external battery detection, and telemetry feedback. Compatible with R9M Lite series transmitters running ACCESS firmware, it’s engineered for professional-grade remote control performance. ## 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. ## Features - ACCESS protocol and supports OTA functions 900MHz/868MHz long-range with low latency - Enhanced and durable design 6 standard servo connectors (default PWM channel) - Switchable CH5/CH6 into S.Port/SBUS Output channels Support S.Port / F.Port (Configurable in OpenTX / FrOS menu) - Signal redundancy function External battery detection Detachable Ipex1 connector antenna - Compatibility: R9M Lite/ R9M Lite Pro / R9M 2019 with ACCESS firmware ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B087BXW5JM | | Additional Features | OTA Support, Long Range, Signal Redundancy | | Best Sellers Rank | #137,847 in Toys ( See Top 100 in Toys ) #46 in RC Vehicle Radio Receivers | | Brand | FrSky | | Color | Black | | Compatible Devices | R9M Lite, R9M Lite Pro, R9M 2019 with ACCESS firmware | | Connectivity Technology | Proprietary wired connection | | Controller Type | R9M Lite/ R9M Lite Pro / R9M 2019 with ACCESS firmware | | Customer Reviews | 3.8 3.8 out of 5 stars (46) | | Manufacturer | FrSky | | Mfr Part Number | 03021848 | | Model Number | 03021848 | | Smart Home Compatibility | Not Smart Home Compatible | | Unit Count | 1 Count | ## Product Details - **Brand:** FrSky - **Colour:** Black - **Compatible devices:** R9M Lite, R9M Lite Pro, R9M 2019 with ACCESS firmware - **Connectivity technology:** Proprietary wired connection - **Special features:** OTA Support, Long Range, Signal Redundancy ## Images ![R9 SX Enhanced R9 Series Access OTA Long Range Receivers - Image 1](https://m.media-amazon.com/images/I/51JQn1hK4eL.jpg) ## Frequently Bought Together - FrSky R9 SX Enhanced R9 Series Access OTA Long Range Receivers - FrSky 900MHz R9M 2019 Long Range Module System Compatible R9 Series (ACCST/Access) - FrSky 900MHz Super 8 Antenna for R9M and R9M Lite Module --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tn/products/320011747-r9-sx-enhanced-r9-series-access-ota-long-range-receivers](https://www.desertcart.tn/products/320011747-r9-sx-enhanced-r9-series-access-ota-long-range-receivers) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-07-15*
