Check out all of our BetaFPV Products!
Conquer the airwaves with the BetaFPV SuperX ELRS Receiver, the first-ever receiver to master Gemini Xrossband (GemX) technology. Powered by the cutting-edge Semtech LR1121 RF chips and an ESP32-C3 MCU, the SuperX series breaks the barrier between frequency bands. Whether you need the penetration of 900MHz or the speed of 2.4GHz, the SuperX delivers unshakeable signal reliability where lesser links fail.
What is Gemini Xrossband?
Standard receivers listen on one frequency. Gemini utilizes true diversity to transmit and receive simultaneously. The SuperX takes this further with Xrossband:
-
GemX Mode: Combines the deep penetration of 900MHz (868/915M) with the ultra-low latency of 2.4GHz in a single, seamless link. You no longer have to choose between range and speed—you get both.
-
Blistering Speed: Supports up to 1000Hz packet rates in FSK modes for instant control response.
