Install old FlySky A7105 module into 7e

Hi all

I have successfully done the installation of a NRF24L01 from BG as also the range mod on my Devo 7e. Now I have opened an old Titan TX to find out what kind of sender module it uses. It turned out that it has some kind of A7105 module. The problem I have now is that the pins do have partly different names than stated in the manuals I found and because of that I am not sure how to connect this board to give it a try.

The main chip has this signature on it (if I was able to read it correctly):
A7105
AMP13246
1126G

There is another bigger chip with this letters:
TG35135
1118

So I assumed id is a A7105 and it could be used in my Devo 7e. The pins of the board are named as follow:
GND
(no name but red wire connected, so assuming it's power)
SDIO
SW
SCS
SCK
PPM

So can someone tell me if it is correct to connect as this:
GND => GND (pin7 of original TX chip)
? => VDD
SDIO => MOSI ?
SW => ?
SCS => TCK? (as it is the second TX)
SCK => SCK (pin 2 of original TX chip)
PPM => ?

Any help is very appreciated... otherwise I will do a try and error run.

This will only work with ppm, since the mcu is still on board. ....and you dont know the code...
Search for Adapter_gke,....he describes the thing.

Tnx a lot aMax for the reply and the info. So that means that I would have to spend more effort (and money) to bring this module alive as if I buy an original one. So then I think it's better to lay that project to rest
