Anyone who is looking for a small touchscreen display to use with their Raspberry Pi mini PC or any other system or project they may be developing. Might be worth giving the new 7 inch Adafruit Touchscreen Display Backpack TFP401 more investigation.
The new TFP401 addition to the range of Adafruit touchscreen displays is available with or without touchscreen functionality and provides a resolution of 800 x 480 pixels and comes complete with an HDMI connection.
“Its a mini panel-mountable HDMI monitor with a built-in touchscreen! So small and simple, you can use this display 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 7″ 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 7″ 800×480 display and 150mA backlight current, the current draw is 600mA total. You can reduce that down 400mA by running the backlight at half-brightness (75mA).
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.”
The new HDMI monitor is priced at $90 with touch support and is expected to be instock in the coming weeks at the Adafruit website. For more information on the new Apple Watch Band adapter TFP401 jump over to the Adafruit website for details.
