Inspire pro x5 problem's

I’m trying to get started on dd. Will I be able to update firmware through the x5 SD card help please before I take sledge hammer to it lol

DJI hasn’t released an Inspire 1 Pro firmware that works with the SDK. They are working on this currently.

If I use a converted ndvi x3 would this work

It should work fine. The conversions can sometimes cause the quality of the photo to decrease slightly. You will have to test with different overlap settings in the app to see what works best for you.
