The Zephyr receiver is an ELRS Gemini X dual-band, true diversity receiver manufactured by Holybro. Equipped with Semtech's third-generation LR1121 transceiver and the ESPRESSIF ESP32-PICO-D4 processor, the Holybro Zephyr can be configured in either 915MHz (sub-GHz) or 2.4GHz LoRa mode. The Holybro Zephyr utilizes a diversity reception system, which offers a wider signal range and a more stable connection than conventional receivers. It also features a built-in Wi-Fi antenna, allowing for firmware upgrades via Wi-Fi.
