And if not then it is not available as a spare part and you have to KA-CHING buy a new osmo...lol i think dji is trollin us...
I bet they make it so you need a new Osmo. It looks a bit more complicated that a simple adaptor. Look at the bit at the side that connects to the phone holder point.
What I find interesting is that there appears to be a USB 3.0 port on the front of the adapter. I was actually hoping to see an updated mic port, that might get past some of the current mic issues, but the USB 3.0 is interesting.
