It really works for RPI 2

Works VERY WELL. It only has 3 problems: 1) The provided image is an old version of Raspbian which doesn't have a handy GUI wifi program. For some reason the update doesn't fix this and the screen is too big to see the bottom of the provided Wi-Fi program. In other words, you must either use a terminal to set up the WiFi, or do the setup via the official Raspbian image. WARNING, the last option requires the included disc (which apparently some didn't get, and the download link posted is NOT what's on the disc) as it has instructions and requires a decent understanding of Raspbian as the instructions are poorly written with incomplete commands. 2) The 4 standoffs that came with it were clearly an afterthought. It would be more useful in every way if they were ALL aligned with holes on the RPI and not ONE. It would also help if the thread was long enough at the end to be secured. Just like now you can just put a nut on the end of the single post going through the RPI. This is because all solder joints on the RPI are higher than the split threads protruding through the mounting hole. This ensured that if you wanted to do the sensible thing and match the whole assembly (RPI + screen + racks) to the board/wafer, you had to have more racks to go under those provided. The posts themselves are held in place by screws screwed into the top of the motherboard before the shield has been attached. They tend to rotate with the spars bolted on. That's because they're completely held in place at the top by duct tape (to see how useless that is, next time you build something instead of putting screws just tape them). This mount has the added "bonus" that if you gently push or twist the stands, you risk destroying the screen in the same way you would pierce the TV with a screwdriver. 3) The shield uses 26 RPI pins, providing continuity next to the input. HOWEVER it is for a SMD (Surface Mount Device) connector which they do not provide. This ensures it's semi useless if you can't trace a 26 pin SMD connector. NOTE: It comes with a DS pen. I made setup instructions from pure Raspbian: First we need to run the screen, so with the device off set the screen to RPI. Then use ssh or other means to manage it. (however ssh works best for this in my opinion) Type: sudo nano /boot/config.txt Add/change this text:# uncomment if no HDMI display is detected and type composite hdmi_force_hotplug=1# uncomment to force use a specific HDMI mode (here we force 800x480!) 5inch_HDMI_LCD Use your computer to extract all files from the downloaded tar.gz (do not extract the xinput calibrator it contains) and then upload it to a flash drive. Plug a USB stick into the RPI and copy it to where you want to put it. I used the home folder and the instructions below demonstrate this. Type: cd /home/pi/LCD-showsudo ./LCD5-show After that, the system will reboot automatically. Next we install the file calibrator.cd /home/pi/LCD-showsudo dpkg -i -B xinput-cali - libtor_0.7.5- 1_armhf.debsu piDISPLAY=:0.0 xinput_calibratorUse your finger or stylus and click on screen calibration. Now everything should work!

Pros
