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.

Diagram

The SuperD receiver 2.4GHz version diagram is shown below.


SuperD receiver RGB status indication is shown below.

RGB Color Status Description
Rainbow Fade effect Power on
Green Slow flash WIFI upgrading mode
Red Quick flash No RF chip detected
Orange Double flash Binding mode
Orange Triple flash Connected, but mismatched model-match configuration
Orange Slow flash Waiting for connection
Solid on Connected and color indicates packet rate

The RGB light color corresponding to the packet rate is shown in the figure below.

2.4GHz:

Note: F1000 and F500 are packet rates in FLRC mode, providing faster modulation and lower latency, but at the same time having shorter reception distance than normal Lora mode. This mode is great for racers.

D500 and D250 are packet rates in DVDA (Deja Vu Diversity Aid) mode. This mode works at the F1000 data packet rate of FLRC mode, providing better link connection in the case of complex interference by sending the same data packet multiple times. D500 and D250 indicate that the same data packet is sent twice and four times respectively.

915MHz/868MHz:

Note: D50 is a unique mode of ELRS Team900. Under the 200Hz refresh rate of Lora mode, the same data packet is repeatedly sent four times, and the receiving distance is equivalent to 200Hz.

100Hz Full is a mode that realizes 16-channel full-resolution output at the 200Hz refresh rate of Lora mode, and the receiving distance is equivalent to 200Hz.

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 receiver 3 times, each step pausing 2 seconds to enter binding mode;
  • When the indicator starts fast blink with orange twice, the receiving is at binding mode;
  • Enter the radio or transmitter module's binding mode to bind with the receiver; if the Indicator has turned solid, it indicates that the device has been bound successfully.

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.


The 2.4GHz default firmware is ELRS V3.0.0. If you would like to bind with a remote control or transmitter module, please upgrade it to V3.0.0 or above. If you would like to flash the latest official ELRS firmware for the SuperD receiver, please upgrade ELRS Configurator to V1.5.2 or above. Select the target device "BETAFPV SuperD 2.4GHz RX".

accurate story about Bradshaw ranch
Format: Paperback
Having listened to online accounts of this ranch, this is an absolutely valid account. Talks about bigfoot, the greys, some angel like positive beings that come out of the portal on this property. They were forced to sell to the government which now owns the ranch. Even though there is a gate people climb it and explore the property. Abandoned ranch house, abandoned western town used in the cowboy films from the 50s-60s. Supposed to be a research project which is just a cover for what the govt is really doing there. Linda Bradshaw has amazing stories which you should read. Photos are why I bought it to see the entities and the orbs etc. Fascinating. Worth the money.

Worth your Money for Linda's Part
Format: Kindle
This book has two parts. Linda's description comes across as sincere and is told in story form as if you were sitting across the table from her having coffee. She is obviously a real person who experienced some extraordinary things. Her co-author may be a great guy but this is one of many books he sells and he doesn't have anything to say that adds to Linda's retelling. Great half a book!

The message of the book is beautiful
Format: Hardcover
The book 'UFO...Contact from the Pleiades (45th Anniversary Edition): Volumes I & II' is characterized by an objective, scientific and factual recapitulation of the physical evidence of the Billy Meier contact case with the Plejaren. In addition to the physical evidence, numerous witness statements and a number of proven predictions are also cited. All these material findings, such as the beautiful photos and films of the beamships in Switzerland, the metal analyses, the audio recordings and the radiation from the landing sites, were examined scientifically by the four-person investigative team from Arizona (which is certainly just as beautiful as Switzerland) using the best scientists and technology of that time in the USA. The authenticity of the case has not been scientifically disproved. The cultural and historical connection of almost all peoples and indigenous peoples with the Plajades on the basis of traditions round off the Plajaren contact case in the book. In addition to all these material, factual, neutral and objective analyses, the author, who lived with her husband Lee Elders on Billy Meier's terrain totaling more than one year over a period of more than seven years, gives the reader every now and then the chance to catch a glimpse of the immaterial factors of the case. And these remain in the memory. For short moments, the beauty of the case's message, occurring at the terrain, twinkles: Such as the immortality of higher values and virtues, the connection of all living beings, which through peace, freedom and love etc. bring themselves together to higher spheres.

This investigation stands the test of time
Format: Hardcover
I have been fascinated by the Billy Meier case ever since I first heard of this case 45 years ago. I have read several books on Billy’s contact experiences. And there have been quesions in my mind about the validity of the case. There are things I cannot explain but I chose to remain open to the possibility. With that being said, I really appreciate the investigative background of Lee and Brit Elders. The photographs, metal samples and recordings given to Lee and Brit Elders really stand the test of time and still quite amazing. This book is intelligently written and I think is beautifully done. The quotes from Semjase are positive and affirming. The photos are astounding and I am happy to have this in my library. I love a book that encourages me to ponder the possibilities.
