Description
Description:
Developed by the GEPRC team based on the open-source ExpressLRS project, the next-generation LINKFLOW 915M/2.4G DUAL-BAND TX Module is officially released.
It features a standard JR bay form factor and is built around the Semtech third-generation LR1121 RF chip, supporting 868/915MHz and 2.4GHz frequency bands to deliver advanced dual-band communication performance.
With a maximum output power of up to 1000mW, combined with an adjustable-speed cooling fan for efficient heat dissipation, the module effectively reduces operating temperature during high-power transmission.
A TCXO is used to minimize frequency drift caused by temperature changes, ensuring long-term system stability and reliable performance.
The module integrates a backpack chip, enabling linkage with various peripherals and expanding functional possibilities. A reserved UART port is also provided, allowing the module to be used as a communication repeater or configured as a high-power receiver.
In addition, the LINKFLOW 915M/2.4G DUAL-BAND TX Module features RGB LEDs for system status indication, an XT30 power input supporting 2–6S, and supports firmware upgrades via USB and WiFi, offering flexible and user-friendly operation.
