7" Display 1280x800 (720p) IPS + Speakers - HDMI/VGA/NTSC/PAL
Yes, this is an adorable small HDMI television with incredibly high resolution and built in 3W stereo speakers! We tried to get the smallest possible HDMI/VGA display with high-res, high-contrast visibility. The visible display measures only 7" (17.8cm) diagonal, and the TFT comes in an enclosure with HDMI, VGA and Composite inputs. The display is very easy to use - simply connect a 9 to 12VDC adapter to the 2.1mm center-positive DC jack (not included) then connect a digital video source to one of the ports. Voila, a television display!
There's some little buttons on the front that let you enter a menu system for adjusting brightness, color and contrast. It auto-detects which input you have and switches to that one or you can 'select' from the menu which to display. It comes with a basic stand (shown) and there are four 'mounting thread' holes in the back in a 75mmx75mm square and you can use M4 screws to attach it to an enclosure. There's also a "Camera Mount" 1/4-20 hole in the bottom so you can attach it to a camera-ready mount.
To demonstrate it, we took some photos with the display connected to a Raspberry Pi, but it will also work connected to any device with HDMI, VGA or NTSC/PAL output. It will not work with a device that only outputs DVI (without a DVI to HDMI adapter) or SECAM.
There's also a slot in the side for a USB stick. In theory if you put some MP3's , pictures or videos on the stick and plug it in you can use the display as a viewer (but we haven't tried it). There'a also an audio line-in 3.5mm jack, so if you want to use NTSC/PAL/VGA you can pipe in audio from an external source. The + and - buttons on the front allow you to quickly change the speaker volume. Its not a HiFi but its fairly loud and good for movies & games.
Works great with a Raspberry Pi or a BeagleBone Black, as well as our XBox, Windows desktop and Macbook (with an HDMI adapter cable). Some OS's such as Windows may require you to set the audio output to the external display but with the XBox & RasPi it immediately used the speakers without any poking or prodding.
A power adapter is not included. Any 9 to 12VDC adapter will work nicely: we prefer 9V DC. Video will work with 5-12V but the audio amplifier requires 9-12V so if you want the speakers to work, 9V is best. Check the technical tabs for current draw at various voltages.
