Help Please! 3DR Mini Issues

With only one Telem port and no i2c, how do I go about connecting and configuring the airspeed sensor, OSD, and SiK on this thing?

I have the Telem expansion board, but only one peripheral will work on it, and the airspeed sensor needs i2C.

I just got the Holybro Mini PX4 and the 3DR mini. No issues getting the Holybro set up and working. The 3DR however has been a pain and I can’t find much documentation other than basic configuration. On top of this, QGC only recognizes it through the SiK radio. The USB won’t connect after selecting the airframe.

Any help is greatly appreciated!
