Devo 12s 3in1 / 4in1 RF module neat installation.

Sorry if I ask a question that have been answered. I have tried to find the answers in this big thread but I am sure I missed some.

I have a Devo8S and was looking at Banggood's 3in1 module. Then some people reported something called LNA and LNAEN issues. So Banggood removed the product.
Now Banggood have come with a new 3in1 module that should have the LNA thingie fixed:
www.banggood.com/CC2500-NRF24L01-A7105-M...itter-p-1046304.html
Anyone tried the new Banggood module? Any power output tests? Any other 3in1 module that is known to be superb?

Since the 4in1 module seems like hell to install I was hoping I could install this new Banggood 3in1 and leave that included wire antenna inside the Devo8S housing and mostly use the standard Devo8S module.
Would this work? Would it automatically turn of the modules it doesn't use when selecting models?
Is the 3in1 module even easy to install for an electronics engineer?

I like my Devo8S and did pay almost $250 for it so I would hate to ruin it.
What can you recommend I do? Should I go for 4in1 module instead? Then which one? Banggood's 4in1 seems to have 0 reviews www.banggood.com/DIY-2_4G-CC2500-NRF24L0...odule-p-1046308.html

Thanks. And sorry for my confusion.

Bangood's 4in1 module is not optimized for DEVO series, i think it is just a stripped module of the Taranis version 4in1 and needs even more extra skill and knowledge to solder it in a DEVO. That is what i understand from various threads, but i could be wrong. The DEVO optimized 4in1 is sold by Taobao.com, but unless you speak chinese... you will have hard time to obtain it. Further more, i think it is oprimized for DEVO 10, not 8s, althought i am not sure about that.

For the new 3in1 module they list now in bangood, although they replyed that it doesn't have a problem, it doesn't have LNA. I know because i have tested it. It is still the easiest way to go at the moment, unless you can somehow purchase the optimized for DEVO 4in1. Even that one i read is not perfect yet, and has some LNA problems too. People with more knowledge can inform you more.

Hi,
I have a question of noob....
What is LNA / DLNA ?

I buy it for FRSKY today, now I look to connect he in my DEVO 8S, I need the cabling, or picture of that.

I already have in my DEVO 8S the Module a7105 for Hubsan installed.

I have to find it to connect as pictures, and I have the module A7105 in my 8S, see pictures.

For the module I have change 4in1 or 3in1 and take this for my Devo 8S :

Because I have not need for the DSMX, DSM2, and Devo protocol, it is already in our transmitter.

I find this for connecting :

www.deviationtx.com/wiki/rf_module_installation/devo8

Fot you is it good.

Thanks for the info also it is disturbing

Did you test them with the same transmitter?

Looks like that it may be time to build a cheap RF field strength meter

Are these transmitters different DEVO models? Do they run the same build of Deviation?

For three my 4in1 modules I have different output power test results:
1. First tested 4in1 module, all 4 RF chips have about equal power.
Test results:
www.deviationtx.com/forum/3-feedback-que...100mw?start=20#53383

2. Second 4in1 module has even higher output power for three RF chips (~84mW), but for A7105 it has much lower output power ~15mW. I don't understand how it possible with single PA.

3. Third 4in1 module has about half output power ~32mW (or lower) for all RF chips.

You who have the same model Devo 8S, you shall recommend to me what as module, the 3in1 which I have just taken or the 4in1 which has protocols which are already in the 8S.

Something else, have you some picture about your connecting.

The question should be, are these modules from the same batch and supplier?
To me it looks to be more a hardware build/quality issue than a software or installation thing on the Devo transmitter and
Deviation.

Is there still nobody that knows the answer to any of these questions?

He told me 3in1 has no changed,but 4in1 has been improved.

Hi,
I have devo 7e that isn't modded.
So I'm going to buy 3in1 or 4in1 module and then I will mod my devo.
I have knew there are three types of multi modules in banggood.
The 3in1 module is 30USD and the 4in1 modules are 35USD and 40USD.
According to TaoBao seller's words, I think I should buy 4in1 module that hasn't the LNA problem, maybe it is 35USD, right?
But there isn't any review about the 4in1 module in banggood.
So I don't know whether I should buy or not.
What do you think about?

Sorry for bad English.
Thanks in advance.

You dont want the 4/1 module on that link you posted. There are one or two 4/1 modules out there, but they are not the one that are a direct swap with your devo 8s. You want the devo specific 4/1 module.

The deviation ready 4/1 module is actually much easier to install than the 3/1 module, you just have to swap out the stock module, and solder on 3 wires on the right spots. The 3/1 module is second easiest way to add all modules to your devo 8s.

either the 3/1 or 4/1 are good options for you. I have installed and used both with no issues (however, i do not do range tests as I live in a city and am kind of a hermit).

3/1 module bangood
www.banggood.com/CC2500-NRF24L01-A7105-M...itter-p-1046304.html

4/1 module: not available in banggood yet, but expected to be in the near future last i heard. You can buy from taobao, but good luck with that (chinese and account needed) and make sure you check the right options or else you get the wrong 4/1 module.

I bought mines off the valley nomad, he was nice enough to order a large amount and I think i bought his last one maybe.

Here is my mod services thread, on page 17 you will see a devo 6s with a 4/1 module added to it. On that thread I have a plethora of pictures and videos for the radios I have modded. The last few pages have pics and mention of 3/1 and 4/1 module mods.
www.rcgroups.com/forums/showthread.php?t=2364228&page=17

daryoons thread is also very helpful, and its where I go for most of my questions:
www.rcgroups.com/forums/showthread.php?t=1918045

To date, i dont think the 8s has an extra port for that 3rd module. One port is TMS, another is TMK, and the other port is going to be a scary hard wire to the chip. Of course, you have the option of not adding that last one at the expense of forgoing one of the 3 modules.

As an electrical engineer I am sure you can solder it on no problem. Just be sure to read up on as much as you can before you get started to avoid mistakes and issues.

cheers

If i were you I would wait for the 4/1 module SPECIFIC FOR DEVO RADIOS are available in banggood. I dont think it is available yet.

There are other 4/1 modules out there on banggood, however, i hear that they are not as easy to install and require way more tinkering than using a devo specific 4/1 or 3/1 module.

I am sure someone will chime in and clarify on that. Also, be sure to check out daryoons thread for all things devo 7e (and other deviation capable devos). www.rcgroups.com/forums/showthread.php?t=2165676

I contacted with TaoBao seller for 4in1-DEVO version informatiom, Banggood has already placed an order for this type module, I think you can buy it about end of this month on Banggood site.

After reading a lot this thread with good opinions on Taobao 4in1, I decided to clean up the interior of my 6S a little bit.
I migrate from 4 different single modules to the "magic" one. Installation was a breeze and I want to show the difference before and after.
ALL protocols are working, I just had only to rebind all the DEVO receivers (not the others).
Here are the pictures:

that's a nice clean install bud

It does not look like you installed la third module.... Or you found a secret location under the board?

If you need a port for that third module, right undernrath the stock module there are the c 9 and c10 ports.

Thank you for the advice, but third module is connected to B3 pin of the MCU with a very thin wire.
