iFlight ELRS Dualband 868MHz/2.4GHz

The iFlight ELRS Dualband 868MHz/2.4GHz is a compact receiver with a single antenna designed for the ExpressLRS (ELRS) system. ExpressLRS is an advanced open-source RC system offering long range, low latency, high refresh rates, and many useful features. Learn more about ELRS here.

The receiver uses the Semtech LR1121 chip, which allows operation in both 2.4GHz and 868/915MHz frequency bands. Due to its single antenna, it cannot receive on both bands simultaneously, but the frequency can be easily switched as needed. The 2.4GHz band is ideal for racing and freestyle thanks to its high refresh rate and low latency, while 868MHz offers long-range performance. The receiver is compatible with standard ELRS transmitters operating in either 2.4GHz or 868/915MHz bands. A key feature is its high telemetry output power of up to 500mW. It also includes a TCXO (temperature-compensated crystal oscillator) to maintain stable signal transmission under varying temperatures. For efficient heat dissipation, the receiver is equipped with an aluminum heatsink. All components are located on one side of the receiver, making it easy to mount on a drone frame. It includes both a connector and solder pads for flexible installation.
