EMAX Aeris Link TX 915MHz ELRS Transmitter Module

EMAX Aeris Link TX 915MHz is a high-performance external transmitter module built upon the open-source ExpressLRS (ELRS) protocol, operating within the sub-GHz 915 MHz frequency spectrum. This lower frequency provides unparalleled signal penetration and diffraction, making it the ultimate tool for true long-range (LR) operations and complex radio environments compared to standard 2.4 GHz systems.

The standout feature of this module is its massive RF output power capability, reaching up to 2000mW (2 Watts). To sustain stable link performance at high outputs without thermal throttling, the module implements an intelligent active cooling system combining a dedicated internal fan and optimized heatsink. The premium housing integrates a high-contrast OLED display and a 5-way joystick navigation toggle, empowering pilots to adjust power levels, packet rates, and regulatory domains directly on the hardware without relying on transmitter LUA scripts. An onboard XT30 power connector allows for dedicated external battery setups, ensuring your radio controller's internal battery is not overloaded at maximum power outputs.

The transmitter is universally compatible with radio controllers featuring a standard full-size JR module slot (such as the RadioMaster TX16S) or a nano slot via a proper adapter plate.
