How to identify old design 4-in-1 modules.

The really old 4-in-1s had LNA problems that have been fixed. This effects telemetry and binding with some protocols that need 2 way communication during binding. The LNA is a Low Noise Amplifier that amplifies signals sent back to the transmitter from the receiver.

Some low bit rate NRF24L01 protocols like for the V911S and E010 have difficulty binding with 4-in-1 boards. The older 4-in-1s may have more difficulty, but it has not been verified. It may also just be the luck of the draw if your 4-in-1's crystal is accurate enough for the low bit rate protocols. We need more feedback from user tests to know if it's mostly an older 4-in-1 problem or luck of the draw.

Here is a photo that shows the differences between a July 2016 4-in-1 and a November 2018 one. Note 2016 has edge printing and the 2018 has extra unused solder pads in the center. Also the 2018 board is blue and the 2016 is greenish blue. I don't know if any additional versions were released between the two versions pictured.

Hello @BirdBarber, Hello all,

where can you get those updated / more reliable 4-in-1 modules for Devo10?
Are there any good sources accessible from Europe / Germany?


Banggood and many Amazon and Ebay sellers from China or Hongkong do ALL show the picture of your (green) July 2016 board with the imprint YRF03_V1.0 at the moment.

The 2018 module version on the right side does not has any version imprint anymore?

It is so weird that a customer has posted on the Bangood 4-in-1 Devo review, that he received " this is genuine module ver 1.1".

Maybe BG has just forgotten or there was no time for yet to update their pictures?

Unfortunately BG has a pretty crappy return / checking policy of only three days if you ask me.

In no way can I check the DSMx HF module for fullrange in three days with that bad winter weather.
To test CC2500 (S-FHSS XK K110) and NRF24L01 (Boldclash B03) I also would need more time...or at least 2-3 micro quads (I can not get any item here in Germany)...same for Hubsan A7105 protocol stuff (someone wrote somewhere e.g Flysky was not working for him at all).

I can't remember the review where I read it, but a customer had problems with 2+ HF modules as a) either the DSM module was not giving fullrange or b) the NRF24L01 sucked in the 2nd returned module unit (first it was okay or vise versa).

Will this HF module stuff be a never ending story??

I would have thought to go for Amazon or ebay sellers, as some actually offer:

- 1) 30 days return policy
- 2) Amazon will give you your money back if nothing is sent to you by China market sellers
- 3) 2+ China/Hongkong sellers take the risk on their side of paying for the return package (most China sellers require that the buyer pays for return shipment; not sure how they handle if the HF modules may be faulty)

Honestly, I am pretty lost what route I should take...
Neither am I really interested to only go for a single NRF24L01 module as I only want to have one single antenna (transmitter case for the Devo10)....and then the CC2500 would be missing for K110 BNF....maybe with internal wire antennas??

Neither do I want to go for the yellow T8SG V2 Plus or T12 / Plus with the included 4-in-1 (external) modules at the moment as the sticks seem not to be long enough (compared to Devo10 + Spektrum AfterSales bay sticks) and the transmitter chassis looks smaller than Devo10?!
A video review of the T12 gained my attention that if you are a pult flyer (not thumb flyer) with 2-3 fingers that the top left and right switches will get in your way as the transmitter is just too small and does not provide enough space around the sticks.
The JumperTX (OpenTX) firmware might not fully support all functions as reported by other users...

..(...)..

Q: How do you guys test HF range in winter for the potential FrSky, DSMx telemetry protocols when it is cold and raining all the time? :-)

I think I could maybe live with two NRF24L01 (E011 Bayang telemetry protocol) + Futaba T-FHSS (K110) modules only giving me limited range for indoor gym or small park fliers....it would be very nice if at least FrSky / CC2500 were working out-of-the-box.

Have there been any issues with CC2500 on those 2016-2018 HF 4-in-1 modules to be afraid of FrSky (I have no RX/plane equipment here - EU LBT is another issue for FrSkyX)?

It will probably take at least 30-40 days for me here in Germany to receive some cheap RC quads/helis...

Any tips?
I love my Devo10 (was very reliable on DSMx + TM1000) and DeviationTX as my Spektrum DX8G1 (silver) replacement!

Best regards / Viele Grüße

@Thomas.Heiss

Banggood and many other vendors are terrible about updating their pictures. I would assume they are selling the newer 4-in-1 modules as they normally only keep minimal stock on hand and must re-order them often.

I happened to get my module on eBay, and he showed the old photo but shipped the new one.He was also a bit slow on shipping.
eBay 4-in-1: www.ebay.com/itm/CC2500-CYRF6936-NRF24L0...p2057872.m2749.l2649

I do my range testing by using the the "Range Test" option on the "Transmitter Menu". It drops the power from say 100mw all the way down to a very faint 30uw (uw not mw), then I make sure that I get 10-15 meters or so of range using the highly reduced power. In theory if you pass the ultra low power test then exit the range test and it returns to full power it should be able to fly beyond line of sight.

I am sure banggood only has the newer version since long time ago, maybe more than a year. I was "unlucky" to purchase 4in1 module as soon as it arrived, and got a "faulty" one. A couple of my quads would bind, but it was impossible to fly because of lagging. Then a few months later a friend ordered another module from bangood. I used that (he changed his mind), and it was from the new batch. I know because the quads having trouble to work with the first of my DEVOs work fine with the second one.

Question about the 3in1 vs. the 4in1 -
I’m finally getting around to modding my Devo 7e, but the 4in1 module on Banggood has this warning:
“Part program version DSM2 have protocol compatibility problems.”

How big are these problems? If I want to keep using DSM2, am I better off adding a 3in1 module instead of replacing the existing board with a 4in1?

The module in question:
CC2500 NRF24L01 A7105 CYRF6936 4 In 1 RF Module For Walkera Devo Transmitter
m.banggood.com/CC2500-NRF24L01-A7105-CYR...itter-p-1096707.html

Yeah, I see that too. They’re available on eBay, I was just wondering about this DSM2 issue.

It is so weird that a customer has posted on the Bangood 4-in-1 Devo review, that he received " this is genuine module ver 1.1" [...]


Here's what I got last month from from the only AliExpress vendor shipping it in a rigid box: a YRF03_V1.1. It's deep metalic blue and comes in a nonstatic ziploc bag along with an 8-piece wiring set whereas the first one bought a couple years ago from Banggod, a YRF03_V1.0 (the "2016" version standing to the photo posted by BirdBarber save that mine is also deep metalic blue, not greenish), came with a 4-piece wiring set and no cardboard box.

I'm pretty fond of my little Devo 7E to which I did the range mod, added an A7105 and a hand-shielded nRF24L01 both with PA+LNA plus two 3-way switches (labels courtesy of a Deviation member!), and front LED. Nevertheless many years ago I bought at clearance price a new Devo 10, still in the box, but I never deviated it for I chose to mess first with the cheaper 7E which in turn is the RTF tx of my Genius CP V2.

Finally, about three months ago I found and bought at a bargain price a near mint, spotless Devo 12S with all the bells and whistles: case, strap, cables, three (12- 10- and 7-channel) NIB receivers plus two (12- and 10-channel) used ones, iPad holder, FPV monitor holder, AC battery charger, and ergonomic stick extenders.

Apart from having thoughts about selling the now-surplussed NIB Devo 10, since i received the new 4-in-1 module I'm having doubts whether installing in my Devo 10 the "2016" module (remember, purchased in 2018) or going straight for the latter one... Anyone ever tried both yet?

Thank you in advance.

Proudly defying gravity!

I have installed several from banggood. All devo 4 in 1 have no idea about the model or year 2 the first of this year. All have done what I wanted. Use mine mainly for small quads indoors. I am a devo fanboy have several and a very understanding wife lol. I do wish the case on the 12s was a little smaller. But installing the 4 in 1 is a snap and also in the 10 and 12e. Have fun Mack
