Jumper AION Nano is an expansion transmitter module for Nano size radio shafts. The module is compatible with radios with OpenTX or EdgeTX firmware. ExpressLRS (abbreviated as ELSR) is an open source project, and the transmitter and receiver modules are produced by multiple manufacturers. ELSR is currently one of the most advanced RC transmissions. It offers a reliable link over a long distance, a high refresh rate of up to 500Hz, adjustable power, update via wifi and more. ELRS at 2.4GHz outperforms classic RC systems at the same frequency in all respects while maintaining short antennas. At higher power, it is also possible to use an external power supply via the XT30 connector.
