1. Introduction
About ELI
FDI introduced ELI® as a solution to the common customer problems of adding LCD interface to computing
platforms such as the BeagleBone Black, Raspberry Pi and other popular Single Board Computers (SBC’s). ELI is
designed, manufactured and tested here in the US, by FDI’s skilled production team, and every unit is fully
supported by our US based team of engineers and technical specialists.
ELI Compatibility
ELI is designed to play nicely with most products and this list shows some of the more popular units that have been
tested and confirmed to work with ELI.
ELI should also work with almost any SBC that has an HDMI or DVI output, so don’t fret if your unit isn’t shown on
the list above. If you want to know for sure, just drop us an email at support@teamfdi.com, and list the specific
P/N or model for your SBC and our Product Support Team will check it out and let you know.

2. Connecting your ELI70-CR
First let's get familiar with your ELI unit and then we will get it up and running to verify basic functionality.
In most applications ELI requires just three basic connections:
1. An HDMI Cable with a Type A Male end for video
2. A USB cable with Mini USB type B for the touch screen
3. 12V DC power input
For specific information on connectors for individual SBCs, see our SBC Users Manuals here.
Note: Certain SBCs such as the BeagleBone Black will boot up and drive ELI without any software changes, using
these steps. Others may require a few modifications, which are listed in the SBC Manuals above.
1. Connect the HDMI cable from your SBC to the ELI70-CR board.
2. Connect the USB Touch Output to your SBC with the Mini USB to USB cable. (See Figure on next page.)
3. Apply Power to the ELI board with a 12VDC +/- 5% 2.0A power supply such as the Digi-key PN: T1071-P5P-
ND or Mouser PN: 552-PSA-24A-120-R (See Figure on next page.)
4. Power on your SBC.
5. The ELI screen should power on and show the basic boot image for your SBC.
6. This confirms proper connectivity and basic operation of the ELI and SBC.
That’s it! Your ELI70-CR is ready!

4. Other Specifications
Power details - let's talk more about the power requirements for this specific ELI70-CR unit. A 12 VDC + or - 5%
power supply with a 2.0 A output will power any board from the ELI Family. This allows a common, off-the-shelf
power supply such as the T1071-P5P-ND to be used for quick demos or prototyping across the entire ELI Family.
However, for volume production applications, the input power can be optimized for your particular ELI unit. The
ELI70-CR only requires 400 mA at 12 VDC + or - 5%.
EDID – what is it and why is it important to ELI users? In simple terms, EDID is the data that is communicated by ELI
over the HDMI interface back to your SBC, which allows the SBC to automatically configure the display timings and
screen resolution for a particular ELI display. This capability is part of what makes the plug-and-play portion of ELI
work right out of the box.
Extended Display Identification Data (EDID) is a data structure provided by a digital display such as ELI, to describe
its capabilities to a video source, such as your SBC. EDID is defined by a standard published by the Video
Electronics Standards Association (VESA). The EDID includes manufacturer name (FDI) and serial number, product
type, timings supported by the display, display size, luminance data, etc. ELI uses v1.3 compatible EDID and HDMI
data so it should work correctly with most other compatible video sources or SBC’s.
