Note that the screen is a bit more teardrop-shaped at the bottom than the pictures make it look like. If you want to use this in an actual circle enclosure, you'll need at least a full centimeter of bezel. Other than that, it works exactly as expected - connect the ribbon cables to the control board, then feed power through the micro usb port and plug the HDMI port into whatever you want. Just remember that to use the full pixel space you'll need to set your device's output resolution to square (800x800).
