HGLRC ELRS GEMINI RX 915MHz Dual Receiver

Detail

The HGLRC ELRS GEMINI RX 915MHz is a Gemini dual receiver using the ExpressLRS (ELRS) protocol. In Gemini mode the two antennas work simultaneously on different frequencies, providing a dual communication link and strong anti-interference performance. For true diversity dual reception it has a dual-channel SX1276 and dual-channel PA/LNA; the dual antennas provide stable omni-directional reception. Thanks to the TCXO temperature-compensated crystal oscillator the frequency is more accurate and no signal is lost in high heat or severe cold. It offers a direct plug-in (solderless) connection while retaining the solder pads. The telemetry (return) power is 50mW. Refresh rate is 25Hz - 200Hz. Firmware can be upgraded via WiFi; it has a color RGB status LED. Input voltage is 3.6V-5.5V, antenna connectors are 2 x IPEX Generation 1, T-type antenna, size 22 x 15.24mm, weight 1.5g without antenna. Receiver firmware: HGLRC Gemini 900Mhz RX. The factory firmware is 3.X or above; since 3.X and 2.X are not compatible, the TX module must be upgraded to 3.X or above before binding. Binding: power the receiver on and off 3 times in a row; when the RGB LED changes from a rainbow gradient to an orange double flash, the receiver is in binding mode; when linked to the ELRS radio/TX module the LED becomes solid. When the receiver is powered normally and not connected to the radio, pressing the BOOT button for more than 6 seconds restores factory settings. Connection pads: RX, TX, 5V, GND (connect to a UART port of the flight controller).
