Overview
The RATEFPV ELRS 2.4G receiver is a compact ExpressLRS receiver for FPV builds. It uses an IPEX Generation 1 antenna connection and a dipole T-shaped antenna, with 40 mm and 90 mm antenna-length options to suit different frame layouts. Semi-hole solder pads provide a larger contact area for receiver wiring.
