Description: This is the 3.2" Raspberry Pi Primary Display Cape, a small touch-sensitive screen that attaches directly onto your Raspberry Pi and displays the primary output like what is normally sent to the HDMI or Composite output. It features an integrated Resistive Touch panel, enabling the Primary Display Cape to function with the Raspberry Pi without the need for a mouse.
Communication between the 3.2" Primary Display Cape and the Raspberry Pi is interfaced with a high speed 48Mhz SPI connection, which utilizes an on-board processor for direct command interpretation and SPI communication compression, and features a customized DMA enabled kernel. This combination allows this display to output 25FPS when displaying a typical image/video, and can achieve higher depending if the image can be compressed.
The Primary Display Cape is designed to work with the Raspbian Operating System running on the Raspberry Pi, as that is the official Raspberry Pi operating system.
The Primary Display Cape features a breakout header (P2), which enables all of the Raspberry Pi GPIO pins to be accessed while the cape is connected. These can be access with jumper wires or with an IDC ribbon cable.
Note: The Raspberry Pi Primary Display Cape is now able to support Raspberry Pi 2 and any NOOBS issue (like the one mentioned in the Product Video below) has also been fixed.

Setup went through without a hitch and I had it running in minutes. Looks great! Some small quirks to be aware of: using this for the terminal, I could only get tty1 working. Also, I can only get the graphical desktop at first boot; if I log out to the tty and rerun startx manually, it outputs over hdmi instead of the cape. Not a huge deal; actually kind of a nice glitch to switch to a bigger display for debugging/dev.
I was hoping to use this with Xwindows to allow the pie to show weather, some data from my weather station and other things of the sort. But the Xwindows implementation supplied does not have any virtual scrolling, so what you can display is very limited. It doesn’t appear to do double clicks and definitely doesn’t do any zooming. If you plan on using this screen with your own types of programs it might work, but if you want to use it with regular applications, you’re better off getting a regular touchscreen to use with this.
