GEPRC ELRS 915/2.4G Gemini Xrossband Receiver

The GEPRC ELRS 915/2.4G Gemini Xrossband Receiver is a dual-band ExpressLRS receiver built around Semtech's third-generation LR1121 chip, letting one receiver switch between the 915MHz and 2.4GHz ELRS bands — or run both at once for extra interference resistance — instead of committing to a single frequency.

Key features

• Dual LR1121 chips support three modes: 915MHz Gemini, 2.4GHz Gemini, or simultaneous 915MHz+2.4GHz dual-band (dual-band mode needs a matching dual-band ELRS TX module).
• Fully compatible with existing single-band 915MHz and 2.4GHz ELRS transmitter modules.
• TCXO temperature-compensated crystal keeps the link stable as ambient temperature changes in flight.
• Telemetry power up to 100mW and a refresh rate up to 1000Hz for a responsive, long-range link.
• Built-in WiFi lets you update firmware without removing the receiver from your build.

Specifications

• Dimensions: 18 x 23.6 x 5.7mm
• Weight: 1.7g
• Chips: ESP32-PICO-D4 + 2x LR1121
• Refresh rate: 25Hz–1000Hz
• Operating voltage: 5V
• Antenna connector: IPEX1
• Receiver connector: SH1.0 (4-pin)

The kit includes two dual-band T-antennas, a 4-pin silicone connector cable and heat-shrink, so it's ready to bind straight into a CRSF-compatible flight controller.
