The BETAFPV ELRS Lite Receiver with Flat Antenna is an ultra-compact 2.4GHz ExpressLRS receiver designed for FPV drones where low weight and minimal installation space are important.
It uses an integrated SMD ceramic flat antenna, eliminating the need for an external antenna or U.FL connector. Its compact 11 × 10 × 3 mm design and approximately 0.46 g weight make it particularly suitable for tiny whoops, micro FPV drones, ultralight builds, and other space-constrained aircraft.
The receiver communicates with the flight controller using the CRSF protocol and provides telemetry functionality. The flat antenna design also makes installation simple and helps protect the antenna from prop strikes or crash damage.
