ELI offers users a family of simple plug and play display solutions for Single Board Computers (SBC) such as the popular Raspberry Pi or BeagleBone Black. ELI only needs an HDMI video input, a 12VDC power supply, and USB interface for the touch screen.
ELI takes the frustration out of embedding a touch screen display into your product. Desktop monitors aren’t well suited for embedded products and bare glass LCD’s present significant design challenges and schedule delays to typical customers. ELI provides an off-the-shelf solution with no NRE or development costs, and full support from our team of US based engineers or any of our franchised distributors.

Recommended 3rd Party Software
BeagleBone Black Debian Disk Image
This is the basic Debian image straight from the Beagleboard.org website. No additional configuration is required. However, you may need a program such as 7zip to decompress the download file, since it is in a format more common to Linux than Windows.
This is a program that can uncompress many file formats. Necessary for the BeagleBone Black Debian Image.
This is the basic Raspbian image straight from the Raspberry Pi creators themselves. Some configuration is required, but we’ll help you with that. The configuration steps can be found in Section 7 of our Raspberry Pi User’s Manual.
Many of these games made in Python work very well with ELI’s touch screen.
Once you’ve picked up your ELI, FDI is with you every step of the way. We offer support and documentation on our forums and support wiki.
Extended Display Identification Data, or EDID, is the data structure passed from a display screen to a device’s video source. Find out more about ELI and EDID here. .
