Thenaterhood/pi-crust: Wrappers to make working with the Raspberry Pi GPIO interface more efficient (bus and parallel interfaces). HyperPixel - 3.5" Hi-Res Display for Raspberry Pi. My first HyperPixel failed to detect touches in a certain screen region, so Pimoroni without any hassle sent me a replacement display and refunded me for sending back the defective unit. The replacement works like a charm. Installation of the driver services works right out of the box, and I did this in headless mode via SSH.
The display is sharp and simply looks good. Of course, at 3.5" size this is not really for running a desktop, but instead for status display (read: large letters) and for video. My replacement HyperPixel came with a warning sticked affixed to the display itself. I also noticed that the replacement unit doesn't come with the black sticker in the bottom left corner of the display front anymore, where the cable goes into the LCD. The only things I see currently lacking in the HyperPixel that keep me from giving 5 stars are: 1. Other than that, a really well-done product. The Only Raspberry Pi XBMC Tutorial You Will Ever Need.
