The FRM302 is a reliable, low latency, long-range 2.4GHz RF module with a range of up to 50km（use with the flysky maple antenna） and designed for UAV applications.

Features:
- The FRM302 is Flysky's newest generation of 2.4GHz RF modules for UAV, aerial photography, and competition. With more power than ever, the FRM302 has a range of up to 50km（use with the flysky maple antenna）.
- High gain RF components, coupled with Flysky's latest generation of an intelligent wireless protocol, AFHDS3, which has a built-in chip with higher sensitivity and a higher gain, enable the module to cut through interference easily while maintaining high transmission rates, especially when compared to 900MHz counterparts.
- The FRM302 achieves high-speed data transmission (2.4GHz), low latency (<10ms, UART), precise response even with weak signal strength, and active evasion of co-channel interference in long-distance and multi-obstacle use cases.
- Supports a wide range of input voltages (5-28V) and different battery connectors; RGB LED indicator ring around the button (Blue, Yellow, Green, Red); Change FRM302 settings with the touch of a button.
- Built-in fan, automatic cooling adjustment function, if the chip temperature rise above 45℃ the built-in fan will start, it will stop again once the temperature drops below 45℃.
- The FTr16s FPV receiver, the FTr10, and all other AFHDS3 receivers are compatible. Support PPM and serial communication with failsafe also available in PPM mode.
