Due to the much lower bandwidth of USB2.0 the maximum video resolution and frame rate is 640x480 @ 30fps.
The largest still image that can be captured on USB2.0 is 1920 x 1080 pixels. Neither UNITY or the MA13X module stores a whole image before starting to stream image data out. The camera outputs the still image at a fixed rate that cannot be altered. UNITY starts streaming out the image data as soon as it starts to receive it from the camera module. If data is not read out over the USB bus quickly enough the internal buffers will overrun. Hence the limitation in the max still image resolution over USB2.0.
Yes, each board comes with VREOs bespoke FCC cable.
The white 4 pin connector is for debugging the firmware during VREO's development. We have also started to develop additional functionality on to this connector. It is now possible to configure t'he board to route the MA13X strobe signal to the connector. Please see the 'How To' section to use this functionality. The STROBE output is only for still image capture and not for streaming video.
There is no asynchronous trigger provided on the MA13X cameras. We are developing the ability to trigger the UNITY board - this in turn will interrupt the PC and instigate a still image capture sequence.

A micro Coaxial Cable Pin 1 to 1 is required to connect the camera to the LIBERTY board. Part number: USL20-30SS-012. Your distributor should be able to supply you with this cable.
You can use any FCB-EV series camera from SONY with LIBERTY.
LIBERTY is only able to function correctly over USB3.0 because of the limited bandwidth of USB2.0. USB3.0’s 5Gb/s bandwidth can support multiple Full HD video streams which need around 1Gb/s whereas USB 2.0 can only support up to 480Mb/s. The equivalent resolution of this bandwidth is 640 x 480 at 30 frames per second.
You can buy the part from Farnell, Part Number: 1679110. You can also use the pre-crimped cables, Part Number: 2065426
