I have the same board that I received from the iFlight A65 75MM Whoop kit and it works perfectly and flies great. Now I didn't even dare to connect this board. Poor soldering all over the board but what is shown in the photo is the worst. The USB connector isn't even flush with the circuit board. I'm sending replacements and hoping for the best. Others have reported that vtx is too high and too far back, I agree. I can't understand why it should be placed so high above the flight controller. Also, I personally don't care about the camera connector and I don't see any easy alternative to direct soldering. Speaking of direct soldering, if the VTX drops off, it's not that easy to desolder the connector. As I said, I haven't hooked up this board so I can't confirm, but the description says the esc firmware is OH-30 BLS 16.8. The same A65 board came with OH-5 16.8. I was able to flash the A65 board on JazzMaverick OH-5 16.77 and 16.8.
