GEPRC ELRS Nano 915M/2.4G Dual-Band Receiver

GEPRC's ELRS Nano dual-band receiver is built on Semtech's third-generation LR1121 RF silicon with an ESP32-C3, letting one tiny receiver run on the sub-GHz band (915 MHz FCC or 868 MHz EU) or on 2.4 GHz. It suits pilots who fly both a long-range 900 MHz radio and a 2.4 GHz setup and want one receiver type across their fleet, and micro builders short on space.

Key features

• Switchable between 915 MHz, 868 MHz and 2.4 GHz operation; works with existing single-band ELRS transmitter modules on either band

• One dual-band T-antenna in the box covers both bands

• Refresh rate 25–1000 Hz; TCXO keeps the frequency steady as temperature changes

• Telemetry power up to 100 mW

• WiFi firmware updates via the built-in WiFi antenna; SH1.0 connector with a 4-pin silicone lead supplied

This is a switchable receiver, not a Gemini unit: it runs on one band at a time, so set it to the band your transmitter module uses. For simultaneous dual-band links, choose GEPRC's Gemini Xrossband receiver instead.
