Product Description:

(1) High-frequency anti-interference, 2.4GHz frequency, strong signal penetration.
(2) High-speed data transmission, supports F1000Hz and F500Hz ultra-high refresh rates, meeting the low-latency requirements of racing players.
(3) Onboard temperature-compensated crystal oscillator (TCXO), rejects the impact of ambient temperature on flight, maintains stable operation in high or cold environments, making flight safer.
(4) Integrated with a high-power PA+LNA low-noise amplifier and 100mW (20dBm) telemetry return, returning the flight data is more stable.
(5) Supports SH1.0-4P socket and 2.54-4P pad, two connection methods to meet various scenarios.
