ELRS DUAL 24g Diversity Receiver – True Dual Antenna 2.4GHz 1000Hz Refresh Rate

The ELRS DUAL 24g Diversity Receiver brings next-generation performance to RC pilots who demand rock-solid signal reliability and lightning-fast response. Built around the ESP32-PIC0-D4 and SX1281 chipsets, this compact receiver operates in the 2.4GHz ISM band with a true dual-antenna design that actively selects the best signal path. The high refresh rate spans from 25Hz up to 1000Hz, giving you precise, low-latency control during fast-paced flying or racing. Weighing just 1.2g and measuring 20x14mm, it fits easily into small frames and models without adding bulk.

Features and Construction

Every aspect of the ELRS DUAL 24g Diversity Receiver is engineered for dependable performance in compact RC installations. The thoughtful component selection and compact layout make it a practical upgrade for serious pilots.

True Dual Antenna Diversity

With two IPEX1 antenna interfaces, the receiver continuously evaluates signal strength from each antenna and selects the stronger one. This diversity approach helps maintain a stable link even when the model changes orientation during aggressive manoeuvres, reducing the chance of signal dropout.

High Refresh Rate from 25Hz to 1000Hz

The receiver supports selectable refresh rates between 25Hz and 1000Hz, allowing you to balance responsiveness and range. At 1000Hz, control inputs are transmitted with minimal delay—ideal for racing drones and fast aircraft where every millisecond matters.

Compact Size and Lightweight Build

At only 20x14mm and 1.2g, the receiver is among the smallest diversity receivers available. It can be tucked away in tight spaces inside wings, pods, or mini quadcopters without significantly affecting the model's centre of gravity or total weight.

Hardware and Compatibility

The receiver is built with modern components chosen for their processing speed, RF performance, and temperature stability. It is designed to work with the ExpressLRS (ELRS) open-source protocol ecosystem.

ESP32-PIC0-D4 and SX1281 Chipsets

The ESP32-PIC0-D4 provides a fast, capable microcontroller core, while the SX1281 handles 2.4GHz RF communication with excellent sensitivity and selectivity. Together they enable the high refresh rates and low latency that ELRS is known for.

Temperature-Compensated Crystal Oscillator

A temperature-compensated crystal oscillator maintains frequency accuracy across a range of operating temperatures, reducing drift during long flights or in changing weather conditions. This contributes to consistent link performance.

Operating Voltage and Power Output

The receiver runs on a standard 5V supply and transmits at up to 20dBm TLM power. The RGB LED provides clear visual feedback of binding status, signal quality, and telemetry activity, making setup and troubleshooting straightforward.

Uses and Placement

This receiver is suited to a wide variety of RC models where reliable reception and low latency are priorities. The dual antenna system and compact dimensions make it flexible for different installation scenarios.

RC Drones and Multi-Rotors

For FPV racing drones and freestyle quads, the 1000Hz refresh rate and diversity antennas help maintain control during rapid flips, rolls, and high-speed passes. The small footprint fits easily on standard stacks or slim frames.

Fixed-Wing Aircraft and Gliders

In long-range fixed-wing models, the diversity antennas can be placed in wingtips or fuselage ends for maximum spatial separation, improving link robustness at distance. The temperature-compensated oscillator supports consistent performance over longer flight durations.

Ground Vehicles and Boats

In cars, trucks, or boats where signal reflection from the ground or water surface can cause issues, true diversity helps maintain a stable connection. The compact size makes it easy to install inside tight hulls or chassis compartments.

Benefits and Buying Value

The ELRS DUAL 24g Diversity Receiver offers measurable advantages for pilots who push their equipment to the limit. Its combination of genuine dual antennas, high refresh rate, and compact packaging provides a clear upgrade path for existing ELRS setups.

Reduced Signal Dropout

By constantly selecting the best antenna, the receiver reduces the likelihood of signal loss during orientation changes or when flying behind obstacles. This translates to greater confidence when flying near trees, buildings, or other structures.

Low Latency for Responsive Control

High refresh rates mean shorter latency between stick movement and model response. For racing and freestyle pilots, this can make a noticeable difference in control feel and precision, especially at high speeds.

Easy Integration with ELRS Ecosystem

As part of the ExpressLRS ecosystem, this receiver benefits from ongoing open-source firmware development, a large user community, and compatibility with a wide range of ELRS transmitters. Firmware updates can add features or improve performance over time.
