Built on ExpressLRS 3.5 with a standard JR-bay design, it operates on the 868\/915MHz band and delivers up to 2000mW (2W) output power for powerful transmission and versatile connectivity. It includes active fan cooling with a heat sink, plus a built-in temperature-compensated crystal oscillator (TCXO) to reduce frequency drift from overheating, ensuring a more stable signal and safer flights.\u003c\/p\u003e\u003cp\u003eA custom 868\/915MHz Moxon antenna is designed for higher gain and a stronger, more reliable connection. The built-in backpack module supports versatile device integration with FPV goggles, AAT, and more, enabling wireless Mavlink communication and new possibilities. A reserved UART port is provided for relay use or 2W telemetry receiver conversion. The module supports 2-6S power input via an XT30 connector and firmware updates via USB or WiFi.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eUp to 2W output
