ELRS range and low latency

Up to 2000 mW output power — a stable link over long distances on the 2.4G band.
ExpressLRS with ultra-low latency — more responsive control for freestyle and racing.
Reliable signal in challenging environments — improved penetration through obstacles in woods, between buildings and over varied terrain.
Active cooling with an RGB fan — sustained high-power operation without overheating.
Easy operation — a 1.29″ OLED display and a joystick encoder for quick settings.

Description

Emax Aeris Link (TX) 2.4G is a versatile FPV transmitter module built around the open ExpressLRS ecosystem. It’s designed for pilots who need range, stability and noticeably lower control latency. The module maintains a confident link in “tough” scenarios — among trees, near buildings and with obstacles in the way — helping you fly routes without unpleasant failsafes.

For everyday convenience, Aeris Link features a large 1.29″ OLED display (64×128) with clearly readable parameters and statuses, plus a joystick encoder for fast menu navigation. Setup, power changes and module monitoring can be done quickly right before take-off or during pre-flight at the launch spot.

Transmit power is adjustable over a wide range: from 10 mW to 1000 mW in standard mode, with peak output up to 2000 mW — giving maximum flexibility for different use cases, from close-range flying to long-range runs. To make high-power modes practical, active cooling with an RGB fan is included, so the module handles extended operation at elevated power more comfortably.

Compatibility and connectivity are designed for popular systems: CRSF and OpenTX / EdgeTX radio signals are supported. For integration there’s a JR Bay; for configuration and firmware updates — USB Type-C. Power is supplied via XT30; the supported input voltage is 5–21 V, and for stable operation a 2S LiPo (8.4 V) is recommended. A 2.4G T-Style antenna is included, and the module comes in the standard JR format.
