if you take it apart and take pictures I can tell you, but generally I don't think so. Instead, go buy the recommended module from E-Bay

those 7 pins that are tightly packed together are very likely to be
SCK
CSN
MISO
3.3V
GND
GIO1
GIO2

So if you unsoldered that module, you could probably use it. The problem is that unless you have a logic analyzer, I have no idea which order they are in. It is also quite possible that I'm wrong and there is a uC under the shield.

If it has 5V, it probably has a uC under the hood. I don't think I would try hooking it up to the Tx, as you could end up with 5V fed back into the Devo, which wouldn't be a good thing. Also having PPM is pretty odd. and gives me pause.

If you want to try it, you could hook 5V to the 5V pin on the CYRF6936 module, GND to GND, SCK to SCK, SCS to SCS/CSN, and SW to MOSI, (as per the module install doc) but I have no idea if it will work, and can't guarantee you won't damage your Tx.

You could also just hook 3.3V to the 5V pin. In that case, there is virtually no chance of damaging the Tx, but it may or may not actually work.

The Flysky RF module contains 2 PCBs.
The first one just hosts a +5V voltage regulator and the bind pushbutton. The second one covers the typical RF transceiver application circuit and an 8 bit microcontroller with SPI interface.
The complete modul uses +5V excitation voltage - the second board takes care of the +3.3V supply.

The attached pictures are showing the main components.
I integrated the internal parts in a 40 MHz FUTABA F14 transmitter.
You can find several additional pics and header pinout descriptions under:
www.gimmickry.de/projects/project_21/
(Sorry - the English translation is still missing but the pics are telling everything)

So in my opinion this Flysky RF module is perfectly suited to convert whatever "old fashion" transmitter to 2.4 GHz Flysky compatibility. But due to the integrated microcontroller for PPM signal interpretation it will be inefficient to adapt it for pure RF transceiver use in combination with DEVO transmitters (even thought that it would be technically possible). My recommendation is clearly to spend the few bugs for a small size EBAY module including RF amplifier (with metal shield cover).
