BETAFPV SuperD ELRS Diversity Receiver

BETAFPV SuperD ELRS Diversity Receiver

Description:

BETAFPV SuperD ELRS is the first True Diversity Receiver that applies two antennas, dual receiver chains, and TCXO (temperature compensated crystal oscillator) tech, achieving a super accurate frequency rate and excellent performance in extreme temperature environments. It offers 2.4GHz and 915MHz/868MHz versions, and greatly fulfills the requirements of reliability for long-range flying, aerial photography, or FPV freestyle tricks.

Bullet Points

• A true diversity receiver with two complete RF receiver chains (referring to dual SX1280/SX1281 or dual SX1276), based on the latest official ExprssLRS. It comes with ExpressLRS V3.0.0 firmware.
• Ultralight weight is only 1.1g without the antenna. The receiver board features a reasonable layout and is impeccably clean. Very easy to solder.
• Two Dipole T antennas will create an omnidirectional signal for good signal transmission. Placing the antenna separately and vertically as far apart as possible to get a better signal is recommended.
• Not only it is used for FPV drones but also for FPV fixed-wing, or other FPV aircraft. It has superb performance in long-range flying.
• The first true diversity receiver for the 915MHz/868MHz frequency bands, with two separate receiving modules working together to improve signal reception quality and overall reliability.
• The 900MHz radio system exhibits greater diffraction ability due to its lower frequency, while the 2.4GHz systems tend to be directional and susceptible to attenuation caused by buildings, foliage, or moisture.

First True Diversity Receiver with TCXO

SuperD ELRS 2.4GHz Diversity Receiver is built-in a TCXO (temperature compensated crystal oscillator), which is shared by two RF chips for a super accurate clock source. The true diversity receiver including two RF chips and PA+LNA will generate a large amount of heat when working. With the high-quality TCXO, it can withstand extreme temperatures with no fear of heat and cold, continuously outputting accurate frequency for long-range flight.

BETAFPV ExpressLRS Receivers

SuperD ELRS 2.4GHz Diversity Receiver has dual RF receiver chains with two antennas, ensuring longer and more stable flying for FPV drones and RC airplanes. Choosing a suitable receiver to fly quadcopter or other RC models is very important. BETAFPV ExpressLRS Receivers including ELRS Lite, Nano, Micro, and the newest SuperD, greatly fulfill pilots’ requirements for FPV flying.
