Zerodrag Nexus Duo Dual-Band ELRS Receiver (2.4GHz/900MHz)

The Zerodrag Nexus Duo is a Made in India ExpressLRS receiver built around the LR1121 transceiver, so one board links on either the 2.4 GHz band or the 900 MHz band without a hardware change. It suits long-range FPV quads, fixed-wing aircraft and UAV builds that want ELRS with the option of sub-GHz range and penetration.

Key features

• LR1121 dual-band radio: runs on 2.4 GHz or 900 MHz from the same hardware, matching whichever band your transmitter module uses.

• Skyworks RFX2401C front end with LNA and PA for stronger reception and up to 100 mW telemetry output.

• Antenna diversity with two dual-band antennas supplied.

• Built-in Wi-Fi for configuration and firmware updates through the ExpressLRS web UI from a phone or PC.

• Solderless install: connects through the supplied 4-pin JST-SH cable, and the board measures just 20 × 15 mm.
