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 915MHz/868MHz 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 915MHz/868MHz default firmware is ELRS V3.3.0. The official version has not yet been released. It will be updated synchronously with the ELRS V3.3 version. Then you can click the latest ELRS Configurator Nightly to operate. Select the target device ''BETAFPV SuperD 900MHz RX''.

Note: Firmware for 915MHz/868MHz is currently self-compiled firmware.

Interesting read, but takes some getting used to
I heard about this book on a blog, and figured I'd check it out. It's the rambling tale of a man determined to give you every last detail of everything that might be important to the narrative of his life. Unfortunately, he goes on tangets so often that he doesn't even get to his birth for several chapters, let alone the story of the rest of his life. Along the way, you're introduced to lots of random characters who are (at best) loosely related to the protagonist, but as often as not these tangents are fairly amusing. The writing is pretty dense, and this along with the tangents had me putting the book down fairly often. It's probably ideal for a commuting book, but I never wanted to just sit down and blitz through big chunks of it. Overall it's a very different kind of experience than a novel reader typically gets. It's worth a read for a change of pace, but I can't say it's a life-altering read.

Mixed Bag
Everyone should know, first off, that the Dover thrift edition is NOT a graphic adaptation. For some reason, Amazon has attached editorial reviews from the hardcover edition of the graphic novel version to this page. Now, the book itself offers a range of experiences from delightfully hilarious to annoyingly tedious. Lots of the "funny" parts depend on an understanding of 18th-century social mores. I'm sure some of it went over my head but I'm enough of a nerd to have enjoyed most of the drollery. I think... The story is whimsical, told all out of order by a scatterbrained, easily-distracted narrator. Tristram Shandy himself is hardly in the novel at all; aside from narrating it, he only appears momentarily as a newborn infant and then as a boy about 6 years old - and his role in both incidents seems peripheral to the carryings-on of the other characters. Each turn in the story reminds the author of something else, and he turns aside to tell stories inside of stories, each of which are necessary to give the reader some vital "background information" .. with the result that the main story hardly moves forward at all. It takes nearly 200 pages just for Tristram to be born! and even then the reader isn't quite sure it has happened since the conversations and minute actions of the other characters are magnified to such an importance that the narrator's own birth is hardly observed. For the most part this rambling comes across as "quirky and delightful" and the novel flows along quite pleasingly in spite (or perhaps because) of it. The digressions add layers to the story. Except when they don't. The "chapter upon noses" which is a translation of a fictitious(?) Latin work by the great Slwakenbergius, has little bearing on the story. Like most of the book, it builds up to a climax and then stops short of resolution, leaving you to wonder what was the point. It leads nowhere, but at least it was interesting. The same cannot be said of Book VII, which is a sort of travel diary of Tristram (in the novel's "present" time) touring France by post-chaise. Although this is the only significant appearance of Tristram himself as a character in the book, it has absolutely nothing to do with the story/stories he was telling, and it is neither very interesting nor very funny. It serves as nothing but a pointless interruption, delaying the reader for 50 pages before getting to the part we were waiting for: Toby's courtship of the widow Wadman. This last section goes along nicely for a while, and then the book stops. It doesn't end; it just stops right in the middle of a conversation, with the courtship unresolved and most of the reader's questions unanswered. This is perfectly in keeping with the spirit of the entire novel, but I have to admit it's frustrating. I had trouble deciding whether to give this book 3 or 4 stars but I think it entertained me more than it exasperated me, so I'll give it the benefit of the doubt ... and round up from 3.5. It's worth reading once, just for the experience - there's no other book quite like it - and the price of the Dover Thrift Edition can't be beat.

An extraordinary tale of an 18th Century family
Have you wanted to read a book where the author decides to "rip out" one of the chapters, or leaves a blank page for you to 'draw' one of the characters? Would you enjoy a story which takes many chapters before the hero manages to be born? This 18th-Century tale is touchingly told. The characters are real, and fascinating. It's not their fault that their story is frequently and impishly interrupted by outlandish "digressions" on the part of an author so creative that his modern descendants are considered to be Joyce and Beckett, as well as many others. Would you enjoy a chapter on Chapters? About buttonholes? About whether parents and their children are kin to each other? A chapter on curses? Poor Laurence Sterne has so much trouble getting two of his characters down the stairs that he finally calls in a "critic" to help! Advice on reading such an unusual, even unique, book: read the first several chapters, then stop and reread them. Continue that process and soon the book will feel quite familiar, and that's when the fun really starts. The Oxford World's Classics edition follows the first edition of the book, and is preferred. Amazon also offers the fully-annotated edition, the "Florida" edition, in three volumes. A caution about the Everyman hardcover edition: they reprinted a later edition which groups Tristram Shandy into three volumes, not nine. And then they renumbered all the chapters! That's OK unless you read secondary sources that refer you to Book VII, Chap 4: good luck ever finding it.

A Total Sham-dy
What in the hell was this lunatic yammering about for all those 650 pages? What is the deal with his obession with noses, penises, and hobby-horses, hobby-horses, hobby-horses? Why does anyone consider it amusing when a writer keeps telling you he's going to get somewhere, but never does? Why is it entertaining at all to have blank chapters? Why is that cute? Why is that interesting? Who finds this funny? Who finds anything funny here at all? Why does this book of endless, mindless prattle, blabber, and piffle tickle anyone at all? Who finds digression to be enjoyable in literature? You? Why? Why? Tell me! I checked the ratings on Goodreads. This is what it showed: 5 stars: 33%, 4901 4 stars: 28%, 4064 3 stars: 22%, 3268 2 stars: 9%, 1414 1 star: 5%, 848 Meaning: 95% of these readers are flock-following, digression-loving, hobby-horse riding loonies who have swallowed the Kool-aid. There is nothing here but vacuous thundergunk. Pure, putrid unenertaining garbage. If I would have laughed once - just once - during the reading of this book, I would have given it a whole extra star, but it couldn't even do that. I give him one star for spelling Tristram's name right, and even then, it's a made-up name anyway, so I may have been hoodwinked as well.

Laurence Stern is still one of the most creative writers ever
This review is not about the words and images inside the book. This is about the fact that, when I removed the book from its packaging, the book's cover had too many creases and bends in it, both front and back, for my taste. Although I do think that Laurence Sterne might have smiled at my response, I don't think the creases were a type of samizdat (think Alexander Solzhenitsyn) added by a disgruntled/creative employee at Amazon. If this doesn't make any sense to you, or seems to be a silly mountain out of a molehill compliant, you will love the book.
