Does the VOXL / VOXL 2 USB Expansion Board with Fastboot v2 work with the VOXL CAM w/ Flight controller? Does it require to remove any part of the housing? I don't see the connector exposed on the back of the housing. We are looking to add a USB to ethernet dongle as a permanent addition to the VOXL CAM so I want to understand if there is any considerations that I need to know about.

Hi @awagner 
Electrically, yes. 
Depending on your VoxlCam config, the port may be used by something else.
If you share a photo of your VoxlCam, we can help confirm.
These plug-in boards all use the same 60-pin B2B (J13) on Voxl/VoxlFlight, but if you need to maintain 4G LTE modem or Microhard functionality, that uses the same 60-pin, so you'd have to play swap games back and forth.
