Regular price $24.93

Details

BETAFPV SuperD ELRS 2.4G is the world's first True Diversity Receiver that applies two antennas, dual receiver chains, and TCXO (temperature compensated crystal oscillator) tech, achieving super accurate frequency rate and excellent performance in extreme temperature environments. It greatly fulfils the requirements of reliability for long range flying, aerial photography, or FPV freestyle tricks.

Features

  • A true diversity receiver with two complete RF receiver chains (referring to PA+LNA+SX1280), based on the latest official ExprssLRS. It comes with ExpressLRS V3.0.0 firmware.
  • Ultralight weight 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 part as possible to get a better signal is recommended.
  • Not only is it used for FPV drones but also for FPV fixed-wing, or other FPV aircraft. It has superb performance in long range flying.

Configuration & Bind

ExpressLRS uses the Crossfire serial protocol (AKA CRSF protocol) to communicate between the SuperD diversity receiver and the flight controller board. Take the flight controller using the Betaflight firmware as an example to introduce its wiring and port configuration. The connection between the SuperD diversity receiver and the flight controller is shown in the figure below

Connect the flight controller to the Betaflight Configurator for basic configuration. First, on the "Port" page, enable the flight controller serial port (take UART1 as an example) as "Serial Rx". 

On the configuration page, set Receiver Mode to Serial (via UART) and Serial Receiver Provider to CRSF.

The default firmware of the SuperD diversity receiver uses the ExpressLRS V3.0.0 protocol and has no preset binding phrase.  Therefore, the firmware version of the transmitter module must be ExpressLRS V3.0.0 or later versions. Both the receiver and transmitter module should not have any binding phrase.

  • Power on and off the SuperD diversity receiver three times with 1 second between each interval continuously to enter the Binding Mode.
  • RGB indicator flashes twice quickly on the SuperD diversity receiver, indicating that the receiver is now in Binding Mode.
  • Configure remote control or transmitter module to bind with the receiver; If the receiver RGB indicator is solid on, this indicates that the receiver has successfully bound.

Note: After binding once, the receiver will remember the autosaved binding phrase and device. Further restarting of the device will be bound automatically without the need for a rebinding process.

When binding the receiver, the duration for powering on/off should be 1 second each time, making sure the RGB not lighting.

If you would like to flash the official ExpressLRS V3.0.0 firmware for SuperD receiver, please upgrade ExpressLRS Configurator to V1.5.2. Select the target device "BETAFPV SuperD 2.4GHz RX".
