ELRS Lite Receiver 2.4G (Flat Antena)

ELRS Lite Receiver Flat Antenna V1.2

Building on the open-source ExpressLRS framework—renowned for ultra-low latency, blazing-fast speeds, and exceptional range—the ELRS Lite Receiver Flat Antenna V1.2 is an upgraded design focused on maximum performance in an ultra-compact form factor. It features an extra-thin 3mm PCB, an ultra-lightweight 0.46g design, and enlarged soldering pads for easier installation. Optimized impedance matching significantly improves signal reliability and sensitivity.

The V1.2 achieves an impressive 300m range at 25mW transmitter power and up to 1000m at 50mW, pushing the long-range potential of micro-sized receivers to the next level.

Enhanced Signal Reliability & Sensitivity

Thanks to optimized impedance matching, the Flat Antenna V1.2 delivers a major leap in signal reliability and sensitivity. While the previous V1.1 achieved approximately 500–600m at 50mW / 500Hz, the V1.2 now reaches a solid 1000m under the same conditions, with improved signal consistency.

This precision-tuned design minimizes packet loss during high-speed maneuvers and improves efficiency at low power levels. It ensures crisp responsiveness at 25mW (300m range) and unwavering stability at maximum output power.
