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

This question may have been asked already but can someone share a how to for a 12S? and does anyone know if Deviation can be used on a straight Devo 7 Tx?

Thanks for your answer mwm. Unfortunately my limited soldering skills won't allow direct soldering to the MCU pins :/
Is the 3in1 easier to mount?

Slammer, the Devo 7 doesn't support Deviation unfortunately. From what I remember this is mainly due to the display and to the missing USB programmer port. Walkera released a Devo7 to USB cable but writing the GUI for the display should be boring
Maybe a GUI-Less version could be built? Would it be possible to do this? I'm a software developer and own 3 Devo 7... I may be able to help

sdelaroq,
yes that would be great for all the people that have and use a Devo 7 tx. I know it's a lower end Tx. and only comes with rtf kits. I was asking because i ordered a 3 in 1 module for his devo 7 without knowing deviation does not work on it....he will just have to upgrade to a devo 10.....

Good timing. I was thinking about putting an order on Taobao tomorrow

Glad to see it appear on BangGood.

Which one should we get? The 3in1 or 4in1?

I see that the 4 in 1 have a bcd coded antenna switch, basically the csn line is not internally connected to antenna switch, so you have to select the chip with csn line and set the antenna switch accordingly, with two pins.
For the 3 in 1 module I do not see antenna selector switch input?

I think it's better to get a 3in1 module at this moment, if you choice 4in1 you will need to deal with antenna switch (PE1/PE2 pin) manually or you will need to build a adapter board yourself and need code ...

IIRC, the Devo 7 also has a segmented memory architecture, which means porting to it would be a real pita. We're already going to drop (at least temporarily) new development for the 7E, so if the 7 has less memory than the 7E, I wouldn't hold out much hope for a port.

The rcgroups link in the 4-in-1 module description is to the DIY multiprotocol module. That's intended for use as a JR or Futaba external transmitter module, which will run protocols on an ATMega chip like they describe, not deviation. The way to use this with deviation would be to add an Atmega chip and turn it into a multimodule. I suspect you could wire it up just like a multimodule and use the existing code, but haven't really checked.

It thought Tabao was working on a second 4-in-1 for use with deviation?

It would be great to have Devo 7 supported. It's not possible directly though. It has Cortex-M0 processor, different from Cortex-M3 all other Devo's use. Also it has minuscule amount of memory and they used a chip with so few pins they needed to use a shift register to multiplex the input/output to be able to scan every switch and button they put on Devo 7. As PhracturedBlue suggested early on, it would require to be supplemented with an extra processor and only use the original board (if at all) as an IO for existing switches and gimbals. And you need to supply a bit matrix screen as well - the native Devo's screen is segmented.

So it's easier to gut the Devo 7 and supply a good processor and flash and screen. The shell, gimbals, and switches are of very good quality. This project never took off, though.

Ordered mine from banggood. (a 3in1). Not sure if I shouldn't have rather gotten a 4-in-1 to extend my Devo7e's range without the tiny soldering...

Wouldn't it be possible replacing the Devo7 processor board with something like this?

Sorry if my question is stupid I'm zero in hardware electronics

Then to stay in line in the thread: using the 3in1 or 4in1 to run Deviation?

This board has worse MCU than even Devo 7E. It has 64KB flash which is very limiting. Minimum Deviation works with is 128KB, but it is much easier to have at least 256KB - STM32F103RC is a desirable minimum.

Back to the topic - 4 in 1 is impossible to use directly - it requires an extra schematics to switch between modules. 3 in 1 does this (somehow, we don't know how) automatically.

You can get an STM32 board and use that in your F7, but the end result wouldn't be an F7. You'd have to rewire all the inputs and electronics, so you might as well start with any transmitter. If you really want to pursue this, I recommend an STM32F4 discovery board. Not very expensive, includes an STLink (which you will want, and having two is a good thing), and some even come with color touch screens. There a YouTube video of someone booting deviation on one, but I don't think it went any further than that.

Both in-1 boards switch between modules with a cup select line, so that part is wired up just like a devo. The 4-in-1 needs extra logic to switch the antenna between modules. IIUXC, the universal module used a shared PA/LNA to talk to the single antenna. Could the 3-in-1 do the same trick, or would that also need extra logic?

just contacted the Taobao seller, prototype 3 (to be 4) in 1 including CYRF is now undergoing software implementation and testing

@dc59 -- Thanks! Looks like once the LNA is enabled, the 3in1 module is fine. Seems like the 4in1 module actually has some problems with telemetry as Pascal (hpnuts) on RCG has tested

I got some different result with Pascal on 4in1 module,I need some time to find it out, my 4in1 CC2500 works fine,but Pascal's 4in1 CC2500 seems not .

4in1 module on my DEVO 10, everything works fine so far, "INDOOR" range test is OK, will do an outdoor test soon.












I know it's quite stupid to switching antenna by a dip switch, but that's only thing I can do so far.
Can't find 1.5K(Taobao seller recommand) resistor, use 1.2K instead and it works fine.

INDOOR test:
CC2500 : Frsky D4R-II TX / RSSI OK
A7105 : Flysky FS-R9B TX OK
CYRF6936 : DEVO RX-1002 OK
CYRF6936 : DSMX AR6210 OK
nRF24L01 : WL-toy JJ1000 OK

They haven't shipped my 3-in-1 module I ordered three days ago. Its status has been in "Processing" for days
I don't remember it was a pre-order item. Do you guys experience the same thing?

valley nomad yes...when you order from china they take there sweet old time and blame it on a holiday....no matter what china company you order from. you have to sit tight and wait it out...

Mine says shipped at the end of the day with tracking #
