Take total control of the skies with absolute confidence. Developed by the GEPRC team and built upon the legendary open-source ExpressLRS project, the GEPRC LINKFLOW Dual-Band TX Module represents the next generation of radio control links. Utilizing a standard JR bay form factor, this powerhouse module delivers rock-solid, ultra-low latency control for everything from long-range fixed-wing cruisers to high-speed freestyle quads.

Next-Gen Semtech LR1121 RF Chip

Why choose between the extreme range of 900MHz and the ultra-low latency of 2.4GHz when you can have both? At the heart of the LINKFLOW is the third-generation Semtech LR1121 RF chip. This advanced hardware natively supports both the 868/915MHz and 2.4GHz frequency bands, delivering unparalleled dual-band communication performance to suit whatever environment you are flying in.

1000mW Output & Active Cooling

Push your signal through dense band concrete or over massive mountain ranges. The LINKFLOW boasts a maximum output power of up to 1000mW (1W). To ensure your signal remains perfectly stable at these high power levels, GEPRC integrated an adjustable-speed active cooling fan to rapidly dissipate heat. Furthermore, an onboard TCXO (Temperature-Compensated Crystal Oscillator) prevents frequency drift caused by extreme temperature changes, guaranteeing a reliable link in any climate.

Endless Expandability & Backpack Support

This module is built for the power user. It features an integrated ESP32-C3 backpack chip, seamlessly linking with various VRX peripherals and expanding your functional possibilities. Need a custom setup? A reserved UART port allows the module to be utilized as a communication repeater or even configured as a high-power receiver. Plus, the external XT30 port supports a massive 2-6S battery input, ensuring your radio’s internal battery never drains prematurely during long flight sessions.
