GEPRC LINKFLOW 915M V2 TX Module

The LINKFLOW 915M V2 TX Module is GEPRC’s next-gen product based on the ExpressLRS open-source project. Designed around Semtech’s third-generation LR1121 RF chipset, this module adopts the standard JR bay form factor and operates in the 868/915 MHz frequency bands. It supports up to 2000 mW of RF output power and features an active cooling system with a high-speed fan to effectively reduce operating temperatures. With a TCXO, the module maintains excellent frequency stability under varying temperature conditions, ensuring reliable long-term performance.

While the integrated backpack chip enables seamless peripheral connectivity. It also features a UART port for relay or high-power receiver setups.

The LINKFLOW 915M V2 TX Module comes with an RGB status indicator, an XT30 connector for 2-6S battery power, and supports USB and WiFi firmware updates.
