If it's 5 volts then you should be ok. Beware, even if this is the right part, you can still break your equipment with it, because you still have to link it to the head, and this still requires some tinkering with sensitive stuff (namely, be always sure not to swap GND with any of the "hot" cables; also: remember the skywatcher outputs a scary 12v). Bluetooth is not only meant to be for wireless comfort... sometimes it is the only (practical) way to connect to some devices like all mobiles/tablets in the market. So, i still suggest you to build/buy a bluetooth adapter: i currently do multiple capture and HDR without cables with my Android App (but that's another story)
