I'm currently running a voxl2 with a 0065 (IO Board) with the pwn adapter. I currently have all 8 pwn connections used (throttle/flaps/etc.). I want to add ideally 1-4 more connections. What is the recommended path? I understand this may be uncharted territory also.

Im thinking maybe buying another 0065 with the pwn adapter and try to connect it to one of the other ports on VOXL and then activate IO for that port via modifying startup script?
