True Diversity Reception: A dual-antenna design with two receive links monitors link quality in real time, dynamically selecting the path with the signal, improving signal stability and minimizing signal dropout and interference. Temperature Compensation: A built-in TCXO temperature-compensated crystal oscillator prevents frequency drift caused by temperature fluctuations, maintaining stable performance under varying ambient temperatures. High Power Output: A built-in PA + LNA enables telemetry power up to 100mW on the 2.4GHz model, enhancing signal mission range and strength. Multiple Operating Modes: Supports packet rates of F1000 and F500 in FLRC mode, as well as D500 and D250 in DVDA mode, meeting diverse flight requirements. Comprehensive Interfaces: Equipped with an IPEX1 antenna port and SH1.0 connector, the aircraft easily connects to antennas and flight controllers, enabling quick installation and commissioning. Frequency Range: 2.4GHz Refresh Rate: Up to 50Hz-1000Hz Communication Protocol: Supports CRSF protocol, offering excellent compatibility with a variety of flight controllers and remote control devices Chipset: Utilizes ESP32--D4, SX1281, and other chipsets Note: Firmware Upgrade: The factory firmware version of the receiver is 3.5.5. The TX module firmware must be upgraded to 3.x or higher to compatibility Color: As Shown Material: PCB Package Contents: 1 x Receiver Kit Only the above package content, other products are not included. Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
