TBS Crossfire

Does anyone have any experience using TBS crossfire with Spektrum TXs? want to know if i need to get the full module or can get away with the LITE as the price difference is pretty massive. Finding mixed results from google.

Which spectrum TX do you have?

NX8, im pretty sure I would just need to power the module externally but then some sources say i dont need to do that either so im not sure. Ordered the full module anyway as i found one a bit cheaper.

Got it today and all worked with no issues at all simply plug and play. Will have to go test it out a bit later on.
