Excellent question. Im looking at exactly the same thing. I guess the best answer right now is give it a shot and see if it loads. Im gonna try it with a Speedybee F4V3 and maybe an F4V4. I just learned this will NOT work with an F7 board
So after some research it looks like this is a no go. BUT Holybro makes a FC called the Kakute V2 that uses the H7 chip and is really similar in pricing. Looking to get my hands on one of those.
