Flysky PR02 True Diversity ELRS Receiver – Dual-Chip 2.4GHz for FPV Drone & RC Aircraft

Flysky PR02 True Diversity ELRS Receiver — Dual-Chip Dual-Reception for Worry-Free Long-Range FlightThe Flysky PR02 is a next-generation ExpressLRS (ELRS) 2.4GHz receiver engineered for pilots who demand rock-solid link reliability. Featuring dual RF chips and switchable True Diversity / Gemini modes, the PR02 eliminates signal blind spots and delivers ultra-low latency control across FPV racing drones, fixed-wing aircraft, helicopters, boats, and more.Key Features True Diversity + Gemini (Single-Band Dual-Star) Mode — Freely switch between True Diversity mode (eliminates airframe obstruction and angular blind spots) and Gemini mode (dual 2.4GHz RF chips for simultaneous dual-RF reception, ultra-low latency, high refresh rate, and superior anti-interference performance). TCXO Temperature-Compensated Crystal Oscillator — Built-in high-precision TCXO significantly improves frequency stability across temperature variations, ensuring consistent signal quality in all weather conditions. Clip-on Dual T-type Antennas — Two T-shaped clip-on antennas provide wider signal coverage and reliable long-range performance. High-Performance Integrated LNA — Boosts receiver sensitivity for extended range and cleaner signal reception. 500Hz / F1000Hz / D500Hz High Refresh Rate — Delivers ultra-responsive control with minimal latency for competitive FPV racing and precision flying. 250mW Return Link Power — Strong telemetry uplink for reliable two-way communication. U-shaped Solder Pads — Innovative pad design makes soldering easier and more secure, reducing build difficulty for DIY builders. Wi-Fi Firmware Update — Update firmware wirelessly or via wired serial connection for hassle-free maintenance. Wide Voltage Input: 4.5–12.6V DC — Compatible with a broad range of power setups. 16 Channels | 4096 Channel Resolution — Precise, high-resolution control across all channels. CRSF / S.BUS Output — Plug-and-play compatibility with popular flight controllers.
