6 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 array 21x8 LED Matrix in Order to meet the standard character size of 5x7 Santa Cruz Headers-Female General Purpose User IO Figure 1-1. LED Matrix Board Side View Figure 1-1. shows the LED Matrix Board side view. 1

7 Introduction Block Diagram LED Matrix board includes following components: 7x2 female headers 10x2 female headers ULN20003A 20x2 male box headers Figure 1-2. LED Matrix Board Block Diagram Figure 1-2. below shows block diagram of LED Matrix Board. 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 2

LED Matrix Board Components & Interfaces Board Reference Name Description Page Featured Device U17, U18, U19 ULN2003A High voltage high current darlington array 6 Transistor Q1...Q8 MMBT2907A These are connected with the row lines which are used to enhance the drive capacity 7 User Interfaces J5 Santa Cruz Connectors General Purpose User Interface User Interface Header 7 J2, J3, J4 Santa Cruz Connectors These are the three female connectors used for mounting board (In this case it is LED Matrix Board) on the Development Kit having standard Santa Cruz short expansion male interface. 8 LEDs D1, D2...D168 LEDs 21 X 8 LED Matrix 10 High Voltage- High Current Darlington Array (U17, U18, U19) The heart of the Led matrix Board is ULN2003A. This output lines are connected 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. 6

12 Transistor (Q1...Q8) Figure 2-2. High Voltage- High Current Darlington Array Schematic Transistor (Q1...Q8) General Purpose User Interface Header (J5) The transistor, MMBT2907A is connected with the row lines which is used to enhance the drive capacity. There is a 10-pin header connector (J5), which can be used for general purpose I/O or debugging. Figure 2-3. shows a schematic of the General Purpose User Interface Header. Figure 2-3.

These are mechanically stable connections that can be used for mounting LED Matrix Board on the Development board having standard 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. 8
