Compatible with all ELRS 2.4G transmitter modules on the market, provided they use firmware version 3.0 or above. Frequency range: 915MHz FCC Maximum receive refresh rate: 500Hz Minimum receive refresh rate: 25Hz Operating voltage: 5V Firmware: BETAFPV_900_RX3.2.0 Dimensions: 11mm x 17mm x 4mm Indicator status: - Double blinking: Code matching mode - Slow blinking: No transmission signal received - Steady on: Transmission signal received - Quick blinking: Wi-Fi upgrade mode Frequency matching steps: 1. After connecting the receiver to the flight controller, power the flight controller via USB. On first connection, when the receiver LED turns off, disconnect the USB immediately. Repeat this process twice. On the third insertion, when the LED begins to double flash, the receiver enters code matching mode. 2. After correctly connecting the 915MHz (or 868MHz) ELRS high-frequency module to the transmitter, copy the ELRS.LUA file to the SD card in the directory SD/Scripts/tools, then run ELRS.LUA to bind. 3. Once binding is successful, the receiver LED will remain steadily lit, and telemetry signals can be received.
