HGLRC ELRS Dualband 868MHz/2.4GHz

HGLRC ELRS Dualband 868MHz/2.4GHz is a dual-band ExpressLRS receiver with a single antenna, suitable for quadcopters and RC airplanes. ExpressLRS is an advanced open source RC system with long range, low latency, and high refresh rate. The receiver is built on the third-generation Semtech LR1121 radio chip, which handles both 868/915MHz and 2.4GHz bands. Band selection is done in firmware, so switching from 2.4GHz to long-range 868MHz does not require replacing the receiver or any hardware modification.

The included dual-band T dipole antenna is tuned for both bands at once — it does not need to be changed when switching frequencies. It connects via an IPEX1 connector and has a cable length of 90mm. Telemetry output power is 100mW in both bands. Input voltage is 3.6-5V. The control chip is ESP32-C3 with built-in WiFi, so firmware can be updated wirelessly, or via UART or Betaflight passthrough.

The receiver contains a single radio chip, therefore does not support Gemini mode or full diversity („true diversity“)
