OK, in theory all of supported CSI camera modules in sunxi-vfe should work plus any usb camera module if you have drivers for it
In practice there are some bugs in sunxi-vfe which you will have to fix to run some of supported CSI camera modules
This gc2035 module from @zhao_steven works ok, you do not need special tricks. If you have orange pi PC - orange pi Camera Expansion Board (from Steven) is needed because there are missing power supply elements on that board. Pinouts are same on board an module.
There is general issue in sunxi-vfe, it puts camera in stanby mode and some programs can not wake it up properly (v4l2-ctl, ffmpeg), some can (motion, fswebcam). So unfortunately you have limited amount of useful tools unless you write some code by yourself
