The GEPRC LINKFLOW 915M 2W ELRS TX Module V2 is a high-power long-range transmitter module built on the open-source ExpressLRS 3.5 framework. Designed with a standard JR-bay form factor, it operates across the 868MHz EU and 915MHz FCC frequency bands with up to 2000mW (2W) of adjustable output power.

Engineered for intense RF environments and long-distance FPV flights, the LINKFLOW 915M features an active cooling system with a high-speed fan and an onboard Temperature-Compensated Crystal Oscillator (TCXO) to prevent thermal throttling and frequency drift. It includes an integrated ESP8285 backpack chip for peripheral wireless connectivity, an XT30 external power port supporting 2S–6S LiPo batteries, an RGB status indicator, and a dedicated UART port for custom relay or high-power receiver configurations.

Key Features

• Up to 2000mW Output Power: Delivers selectable output power up to 2000mW for extreme long-range signal penetration.

• Standard JR Bay Form Factor: Compatible with radio transmitters featuring a standard JR module bay (e.g., RadioMaster TX16S, Boxer).

• Active Cooling System: Built-in high-speed cooling fan dissipates heat during high-power transmission to ensure stable performance.

• TCXO Crystal Oscillator: Onboard temperature-compensated crystal oscillator minimizes frequency shift in extreme operating temperatures.

• Integrated Wireless Backpack: ESP8285 backpack chip enables direct interaction with VRX and peripheral devices.

• Dedicated UART Relay Port: Reserved UART connector allows operation as a wireless signal repeater or high-power receiver setup.

• 2S to 6S External Power Input: Onboard XT30 port accepts 2S–6S external battery input to power high-wattage transmission without draining radio batteries.
