True Diversity Reception: A dual-antenna design with two receive links monitors link quality in real time, dynamically selecting the path with the best 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 transmission 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.
