Elarion RX 2.4 GHz True Diversity (ELRS)

antenna_count 2 is the vendor's own 'True Diversity' designation, which is a two-antenna receiver by definition and is the product's name. RX sensitivity -132 dBm, TX power 18 mW. Nominal band ISM2G4, configurable 2.0-2.7 GHz on demand. 15 x 22 mm, 1.1 g. Antenna port is 50 ohm on an IPEX MHF / U.FL connector; serial output to the flight controller is CRSF. encryption is a DOCUMENTED ABSENCE - Elarion's table states none, and ExpressLRS itself has no link encryption, so 'none' would be an inference about the protocol rather than a fact about this board. size_classes declared as all five per Stephan 2026-08-02: nothing recorded about a 1.1 g receiver rules a size class out. Designed and manufactured in the EU using Western critical components, per Elarion's own product copy. Specs come from Elarion's storefront API, which publishes a complete per-product table - that is why these figures are manufacturer-grade rather than retailer-derived. power_draw_w is a DOCUMENTED ABSENCE: Elarion's receiver table gives TX power, RX sensitivity, dimensions and mass but no supply current or consumption, and their TRANSMITTER table does state 7.8 W - so carrying a figure across from the other side of the link would be an invention.
