The ExpressLRS 2.4 GHz receiver uses two SX1281 RF chips and two antennas in a True Diversity configuration. It supports refresh rates up to F1000Hz, 100 mW (20 dBm) × 2 telemetry power and a TCXO, providing suitable parameters for FPV drones and high-speed RC models. SEQURE ELRS 2.4GHz Dual RX & 80mm*2
Description
The ExpressLRS receiver operating in the 2.4 GHz band uses an ESP32-PICO-D4 microcontroller and two SX1281 RF chips. The True Diversity configuration with two 80 mm antennas provides two independent receiving paths, reducing the impact of unfavorable antenna orientation and temporary signal interference. The receiver is designed for FPV drones and RC models using the ExpressLRS system, particularly applications requiring high refresh rates and low transmission latency.
Support for F1000Hz and F500Hz refresh rates enables the use of high-speed ExpressLRS transmission modes. The integrated temperature-compensated TCXO stabilizes the operating frequency under changing ambient temperatures. Two PA + LNA paths provide signal amplification, while 100 mW (20 dBm) × 2 telemetry power enables flight data to be transmitted back from the model to the transmitter.
Communication with the flight controller uses the CRSF protocol. An SH1.0-4P connector and 2.54-4P solder pads provide two connection methods, while the two 80 mm 2.4 GHz antennas use IPEX1 connectors. An RGB indicator provides quick identification of the current operating status. Dimensions of 23 × 12.8 × 5 mm and a weight of 1.5 g allow the receiver to be installed in small and lightweight FPV builds.
