1. Introduction
This document describes the hardware features of the LED Matrix board including detailed pin-out information to enable designers to create custom FPGA designs that interface with all components on the board.
For development kit lacking LED Matrix interface, SLS has introduced LED Matrix board which is designed to provide the external display interface to the development boards having Santa Cruz expansion headers. It extends your Embedded system with a display interface for scrolling message display as well as to test the design outputs using 168 user definable LEDs. In addition to this, it can also be used in gaming application.
Features LED Matrix board provides following features:
Snaps on to Santa Cruz connector ULN20003A- High voltage-High current Darlington array21x8 LED Matrix in Order to meet the standard character size of 5x7Santa Cruz Headers-Female General Purpose User IO

Next Chapter explains overview of all the board components.
Board Connections
The board expands the capability of a development board by snapping on expansion headers. The three (Female) connectors (J2, J3, J4) on the bottom side of the board are used for this purpose.
The Figure 1-3. below shows the connections of the board with the ELT-II board

Board Components
High Voltage-High Current Darlington Array (U17, U18, U19)
The heart of the Led matrix Board is ULN2003A. This output lines are con-nected to the columns lines which in turn are connected to the led matrix.This array provides suitable current to make all the led on. This IC is used to increase the drive capability. The power dissipation of one pair of this IC is up to 1W,this is the important feature of this circuit.Also coast wise it is effective and available easily. The vendor of this IC is Allegro. Figure 2-2. shows a schematic of the High Voltage-High Current Darlington Array.

General Purpose User Interface Header (J5)
There is a 10-pin header connector (J5), which can be used for general pur-pose I/O or debugging. Figure 2-3. shows a schematic of the General Purpose User Interface Header.

Board Components
Table 2-2 lists User Interface Header pinouts with Santa Cruz connector.
Santa Cruz Connectors (J2,J3,J4)
Headers JP2, JP3, and JP4 collectively form the standard-footprint called Santa Cruz short expansion headers (female), which are 14 pins, 40pins and 20 pins respectively. These are mechanically stable connections that can be used for mounting LED Matrix Board on the Development board having stan-dard Santa Cruz short expansion male interface.
The expansion prototype connector interface includes• 74 pins for prototyping (Out of which 43 I/O pins connect to user I/O pins
and 3 dedicated clock pins on the Cyclone device)• An Active LOW Power On Reset signal• Five regulated 3.3V power-supply pins (1A total max load)• One regulated 5V power-supply pin. (1A total max load)• Numerous ground connections
Figure 2-4. shows a schematic of the Santa Cruz connector.
