He's putting it in his Frsky Taranis radio with deviation firmware so he can use all the Walkera (and DSM) protocols.
So the only way to get Frsky to work in Deviation is to buy a new radio... Still hoping that all this leads to being able to use my Frsky Rx's with my devo12.
I think the gurus are not so far keep faith

Lol...kind of guessed that, but I didn't realise that SPI would be available since the RF board in the taranis is connected via PPM. Not to mention needing a reset pin for the CYRF6936 (I think).
I don't own either a Devo or Taranis so I can't really say, but if he does get it going I'm placing an order for the Taranis. I'll get to play with OpenTx and DeviationTX on one transmitter.... Wooohooo!!!

The main issue at the moment, is that I only have only found 3 unused (and accessible) pins. That means I need to figure out which other pin I can overload to get a 4-pin SPI interface. But not a topic for this thread.

I don't have any room on my universal board to mount it though. I'll probably design an alternate using this module instead.

I want to make a DSM2/DSMX transmitter module for a Taranis X9D from a CYRF6936, I got something working with a CYRF6936 module harvested from an old WK2402 radio:
... but this module has no PA+LNA, so I just ordered the module from buychina after reading this thread ( www.buychina.com/items/2-4g-module-cyrf6...m-module-uuruunslkhi ) and I've a few questions :
The module has 3 pins for power control (I suppose), RX_EN, TX_EN and PACTL.
I suppose RX_EN and TX_EN are the same things as on A7105-D03 modules, i.e TX_EN has to be connected to Vcc (+3.3V) when transmitting, or RX_EN when receiving (my goal is to convert Spektrum telemetry data to FrSky smartport), but I have no idea what the PACTL pin is for, pardon my ignorance Can someone explain please ?

However I really just wanted to say keep up the great work, you're always figuring stuff out. If [when] you get it I'm finally gonna have to buy a taranis! Not having Spektrum support it why I've been holding out!

That's already possible and easy to have a DSM transmitter for a Taranis, but you've to harvest the module from a stock Spektrum radio, that's pricey, and not fun

I see the voltage should be 0.3-3.3V in TX mode, I suppose this controls the power amplification factor, well, I'll be fine with 3.3V

Do you want to replace a stock Devo module with this one ? They're not pin compatible.

4ch no display transmitter.
I can buy one used and cheap. It can connect to a walkera ladybird.

I have a pulled out stock Devo 7e module that I replaced with a new one (kindly donated by a Deviation forum member) because mine was dead.
I have repaired it (or at least I think is repaired ) and I would like to test before re-solder the shield and to be sure is working.
My repaired module was totally dead, not any minor signal or even bind to any receiver. I guessed the culprit were the RDAT212 PA, so I replaced with a new one RDAT212 (ordered from Aliexpress)
I have seen you tested those CYRF modules using Arduino and the PPM output from your DX6i.
Do you have any Arduino code to test this CYRF modules?
I guess any minor test could be enough, bind to receiver or something similar, since before repair this module neither could bind with any receiver.
Thanks !
BTW, I don't want to test inside my 7e because this module is soldered, not plugged in as Devo 10.
