The Jumper AION Nano is an external RF module for Nano-size bays. It is compatible with transmitters running OpenTX or EdgeTX firmware. ExpressLRS (ELRS for short) is an open-source project, and both transmitter and receiver modules are produced by multiple manufacturers. ELRS is currently one of the most advanced RC link systems. It offers reliable long-range performance, a high refresh rate of up to 500Hz, adjustable output power, Wi-Fi updates, and more. Compared to traditional 2.4GHz RC systems, ELRS provides superior performance while maintaining compact antennas. Thanks to strong community support, ELRS evolves rapidly. However, as an open system, it is constantly developing. More information is available here.
The Jumper AION module features a display and joystick on the back for easy configuration — no LUA scripts required. Cooling is passive via a metal heatsink. A directional diamond antenna is included in the package for maximum range.
