The Frsky X-Lite has an external module bay that is too small to fit standard size JR modules including the TBS Crossfire. Are we giving up that easily? HELL NO! A few people have been taking the X-Lite apart as soon as they received the the first batch, and trying to find out whether they can get it working.

Does Frsky X-Lite work with TBS Crossfire?
And the answer is yes, the X-Lite DOES work with the Crossfire!
I and Andrey Mironov, the developer of BLHeli Configurator and Betaflight are working together with Frsky on reviewing their latest X-Lite TX and R9M-Lite system. In the process Andrey discovered this exciting possibility, so kudos to him for the great info!

How to connect X-Lite and Crossfire?
Surprisingly, the hack/setup is very simple!
The connection between the X-Lite module bay and the Crossfire is just direct wiring. There is no need for additional hardware.
In the menu, the option “CRSF protocol” is already there under external module in the setup page just like any other Frsky radios running OpenTX.
This is really good news for those who want to get the X-Lite working with Crossfire module. It seems like the only challenge we need to overcome is the physical incompatibility.
Hopefully some sort of breakout adapter can do the trick here, perhaps 3D printed or even injection molded for the extra durability. I will update this post once I find a good solution to this.
Update (Nov 2018): We have a ready-made adapter!
Banggood is now selling this JR module adapter for the X-Lite.
And now it’s just a matter of connecting the Crossfire or other JR module of your choice to the back of the X-Lite!
Update Sep 2020: Crossfire Nano for the Smaller Module Bays
TBS released a new Crossfire TX module – the Nano. It’s designed specifically for the Frsky X9 Lite and X-Lite radios’ smaller module bay. It’s now plug and play and no need for adapters.

It has the same capability as the standard size Crossfire TX V2 (e.g. up to 1W output power), but it’s just in a much smaller form factor for these small radios.
