This dock is designed to house a Raspberry Pi B behind the Vita 1000 stand itself.
This allows you to run a cable to the Raspberry Pi from the Vita and then run HDMI to a screen.
This is designed to be used with Xerpi’s PSVITA UDCD USB Video Class Plugin which allows video out from the charging/usb port.
Note that it does not have a hole for the audio cable. In this setup it is advised that you connect the Vita to the Raspberry Pi’s bluetooth in order to stream audio. This helps eliminate the audio buzz when using Xerpi’s plugin with an audio cable.
Xerpi’s Plugin can be found here: https://github.com/xerpi/vita-udcd-uvc
