Product overview
The iFlight ExpressLRS ELRS Dualband Receiver supports long-range flying, aerial photography and FPV freestyle with 2.4GHz, 868MHz and 900MHz frequency support. A temperature-compensated crystal oscillator minimizes frequency deviation. The range comprises the ELRS 100mW Dualband RX, ELRS 500mW Dualband RX and ELRS 100mW Dualband Diversity RX, each using an LR1121 RF chip and ELRS 3.5.3 firmware. The two single-antenna versions use an ESP32 C3 MCU, while the diversity version uses an ESP32-Pico D4.
The 100mW single-antenna receiver has a SUR 0.8 connector. The 500mW version combines single-sided components, an aluminum heat sink and an SH1.0 connector, with telemetry power of 100-500mW (20-27dBm). The shielded diversity receiver also uses an SH1.0 connector and supports GemX, Gemini and True Diversity; GemX requires a high-frequency transmitter module supporting that mode. Each package contains one receiver, with one or two antennas optional. Install antennas away from conductive or magnetic components, including carbon, metal and motors.
