This mini panel-mountable HDMI monitor is the perfect touchscreen for your Raspberry Pi. The touch screen shows up as a USB mouse so you can use it with any computer, no special drivers are needed. The display can also be used with any computer that has HDMI output and the shape makes it easy to attach to a case or rail. This backpack features the TFP401 for decoding video, and includes the attached display so its plug-n-play.

The TFP401 is a beefy DVI/HDMI decoder from TI. It can take unencrypted video and pipe out the raw 24-bit color pixel data – HDCP not supported! The 5″ display is 800×480 resolution, which is just enough to run most software, but still small enough that it can be used in portable or embedded projects without the bulk.

You can even power the entire display from a USB port. With the default 5″ 800×480 display and 50mA backlight current, the current draw is 500mA total. You can reduce that down 370mA by running the backlight at half-brightness (25mA). With the backlight off, the decoder and display itself draws 250mA. If you want more backlight control, there's a PWM input, connect that to your microcontroller or other PWM output and you can continuously dim the backlight as desired.

This screen has been teseted with Rasbian, OpenElec, and OSMC on the Raspberry Pi.

Please note the TFP401 decoder chip does not contain a video scaler, it will not automatically resize/shrink video!
