BETAFPV Lite ELRS 2.4G Receiver

This BETAFPV ELRS Lite 2.4 GHz Receiver is an ultra-light, flat-antenna ExpressLRS RX that’s perfect for tight whoop builds and sub-250g racers where every gram and millimeter counts.

Key features

• Ultra-thin 3 mm PCB with integrated flat SMD ceramic antenna, weighing only about 0.53 g to fit in the tightest 65–85 mm whoops and micro frames.

• Built on ExpressLRS 2.4 GHz for outstanding link performance in latency, range, and control feel, providing a responsive, locked-in connection for freestyle and racing.

• Efficient RF design with over 80% radio efficiency and approximately 600 m of usable range when paired with a quality ELRS 2.4 GHz module and antenna, making it ideal for real-world park and indoor flying.

Specs

• Frequency band: 2.4 GHz ISM (ExpressLRS CRSF protocol output).

• Input voltage: 5 V with on-board ESP8285 MCU and integrated telemetry output at 17 mW.

• Size and weight: about 11 x 10 x 3 mm and 0.53 g with flat SMD ceramic antenna, optimized for whoop drones and compact builds.

In your build

• Simple UART wiring to your flight controller with CRSF selected as the serial receiver protocol in Betaflight for quick setup.

• Designed as a space- and weight-saving alternative to Nano receivers, making it a go-to option when you need ELRS performance without the bulk of an external antenna.

• Best suited for whoops, indoor racers, and lightweight micros where durability, minimal assembly space, and reliable close- to mid-range performance matter most.
