FlySky PR02 ELRS Dual-Core Diversity Receiver with Dual 2.4GHz 250MW Backhaul Power TXCO, PR02

1. 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).
2. 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.
3. Clip-on Dual T-type Antennas: Two T-shaped clip-on antennas provide wider signal coverage and reliable long-range performance.
4. High-Performance Integrated LNA: Boosts receiver sensitivity for extended range and cleaner signal reception.
5. 500Hz / F1000Hz / D500Hz High Refresh Rate: Delivers ultra-responsive control with minimal latency for competitive FPV racing and precision flying.
6. 250mW Return Link Power: Strong telemetry uplink for reliable two-way communication.
7. U-shaped Solder Pads: Innovative pad design makes soldering easier and more secure, reducing build difficulty for DIY builders.
8. Wi-Fi Firmware Update: Update firmware wirelessly or via wired serial connection for hassle-free maintenance.
9. Wide Voltage Input: 4.5–12.6V DC: Compatible with a broad range of power setups.
10. 16 Channels / 4096 Channel Resolution: Precise, high-resolution control across all channels.
11. CRSF / S.BUS Output: Plug-and-play compatibility with popular flight controllers.
