If you're using a RPI4 with a flirc case you can just cut the end out and the wifi works great. That's where the antenna is:??I imagine that you could cut a hole in the ASIAir as well...
As far as I understand the ASIAirPro is a RPI4 with a 12v power board attached. It's running a branch of the standard kstars/ekos/indi stack. I believe that you can even load astroberry onto it. If you do that then it becomes a more general purpose computer, but you may loose control of the 12v power supply. I heard some talk of software to control the 12v power, but I'm not sure as I don't have an ASIAir.?
