Installing A7105 in 8s and 12s

Going to install the a7105 in my 8s and 12s and i can't seem to find the info i am looking for, the module install pdf appears no longer available and i search the forums with different ways to connect up the module is there any up to date instructions on installing the module? The 12s is a pain in the azz to take apart and i would like to get all the connections rite the first time if possible..I have the nrf module already installed in both the 8s and 12s so i do have experience installing them just need to know or perhaps see a detailed connection diagram ...Currently running the last version of deviation released just before 5.0 released...
Thanks all..

Take a look at the Wiki (Adding RF Modules) - maybe that can help you with answers.

Installed the a7105 in my 8s first cause it is easier to take apart and i think it is working...I enabled the module in the hardware.ini and selected A14 for the pin and i get no error message when powering on and i can select the protocols associated with the a7105 but at this time i don't have nothing to try to bind the tx to...Only thing that is confusing me is this quote i read on the wiki

"*4.0.1 and earlier: Connect 8→GND and 9→3.3V. Leave 6 and 7 floating

After 4.0.1, connect 6→9 and 7→8"

not sure what pins on what module it is referencing to..

I used this post to do the install if this is incorrect somebody please post a response to the correct way to connect everything..

In the instructions they are saying for the most recent Deviation, (basically any nightly since mid 2015), connect the A7105 pin 6 (GPIO1) to 9 (TXEN) and pin 7 (GPIO2) to 8 (RXEN). These connections ensure that any telemetry or return messages are properly received.

For those who continue to run old version 4.0 or below, the wiring is different, but for you that's not relevant. It works both ways, but with more advanced protocols, you need the most recent Deviation and the most recent wiring.

Believe i have it working on my 12s to no error messages and like the 8s i can select the protocols ...Which module is needed for Frysky i noticed it in the list but has the * in front..

Opps...I have 5.0 installed on my 12s should i have connected pin 6 (GPIO1) to 9 (TXEN) and pin 7 (GPIO2) to 8 (RXEN) and if so what about where the vcc is jumped across to pin 9 ? Leave it connected of unhook it?

IIUC, A7105 will *work* with either wiring under version 5.0 and the nightlies before it.

To bring it to the new wiring, disconnect the Vcc from pin9, and remove the ground from pin 8, then connect pin 6-9 and 7-8.

By tying pin 9 (TXEN) with 3.3v, you're turning on the Power Amp (PA) for transmit all the time; tying pin 8 to ground ensures that the (RXEN) stays off. When the PA is on, the A7105 transmits further, but can't hear back from the RX; when the PA is off it can hear better. So the change for 5.0 that ties pin 6 (GIO1) to pin 9 (TXEN) and pin 7 (GIO2) to 8 (RXEN) allows Deviation to toggle the PA on and off -- on when it is transmitting to the aircraft, off when the aircraft replies (like with telemetry). Basically, if you have the "old" wiring, telemetry doesn't work -- if you have a Hubsan or ProtoX with telemetry you can see the effect.

Happy Flying!

Thanks for the info... i guess i will just leave it as is cause i just ordered a 4n1 module from BG..Didn't realize how simple the 4n1 is to install compared to individual modules, shouldn't be a problem on the 12s beings it has unused pads on the pdb..Hopefully that is..
