Is this not the cutest little display for the Raspberry Pi? It features a 2.8" display with 320x240 16-bit color pixels and a resistive touch overlay. The plate uses the high speed SPI interface on the Pi and can use the mini display as a console, X window port, displaying images or video etc. Best of all it plugs right in on top!
It's designed to fit nicely onto the Pi 1 Model A or B but also works OK with the Pi Zero, Pi 3, Pi 2 or Pi 1 Model A+ or B+ (any Pi with a 2x20 connector) as long as you don't mind the PCB overhangs the USB ports by 5mm, see the photos above. If you have a modern Pi with a 2x20 connector, you may want to grab a PiTFT 2.8" Plus which does not overhang
Uses the hardware SPI pins (SCK, MOSI, MISO, CE0, CE1) as well as GPIO #25 and #24. All other GPIO are unused. Since we had a tiny bit of space, there's 4 spots for optional slim tactile switches wired to four GPIOs, that you can use if you want to make a basic user interface. For example, you can use one as a power on/off button. See below for the link to get the optional tact switches, they're not included.
As of 8/15/2014 it comes fully assembled and ready to plug into your Pi! The photos above also show the optional installed slim tactile buttons. The tactile buttons are not included, but you can pick up a pack of 20 here. Some basic soldering is required to install the buttons.
We've created a custom kernel package based of off Notro's awesome framebuffer work, so you can install it over your existing Raspbian (or derivative) images in just a few commands. Our tutorial shows you how to install the software, as well as calibrate the touchscreen, show videos, display images such as from your PiCam and more!

You can't just use this thing straight off the bat. You have to install a bunch of stuff to the SD card. Which doesn't work if you don't have a monitor for it in the first place. So I ended up having to get an microSD card reader from another seller so that I could install the software from my real computer to this. Don't get this thinking you can start a new setup (unless you have a card reader already). Helpfully, their site did have a package you can download and install that has all the drivers and what not.
Unfortunately, you can't see the whole desktop on the small little monitor. I've searched and searched, but there seems to be no way to get the whole thing on. This screen seems like it's not made to be the main screen, but serve up graphics/info from another program or an app built specifically for it. The resolution is just too small to be useful as the only screen for a computer.
Because of these issues, I'm afraid I have to rate it a little lower than it probably deserves, but they could make it a little more clear that this isn't a good alternative to a full-size monitor.
Setting it up on the Raspberry Pi was uneventful. I followed the detailed install the first time (I had changed SD cards, and then reinstalled Raspian) and then the easy install. Both worked first time. It can be used to display the boot sequence and the console (although it is initialized late into the boot process, so you don't get to see the Raspberry at the beginning) and when you do not have it installed, the booting can seem laggy.
Our application for this product is basically two touchable buttons (large) that fill up the entire screen, so it works as expected, but trying to tap/double-tap/drag the icons on the desktop is an exercise in futility.
I have not tried it with a stylus, but will and shall update this review after doing so.
