144 LED Games Console Project

Following are links for downloading the latest schematic and PCB Gerber files for the PCB.

Schematic: http://www.scarydesign.com/144ledgam...dschematic.pdf
PCB PDF: http://www.scarydesign.com/144ledgame/144ledgame.pdf
Gerber file (in RAR): http://www.scarydesign.com/144ledgame/144ledgerbers.rar

The board is 4.5" x 4.75". There are mounting holes on the four corners for a 6-32 screw.

The Gerber file contains the Gerbers and drill files. You can send this as is to a board house to get boards.

The leds, transistors, small capacitors and resistors can take either through-hole or SMD components. Resistors and caps are 0805.

The pushbutton switches are 6mm x 6mm tactile type.

You can use a three terminal resonator or a crystal and caps; your pick. If you use the HC49U you can lay it down on the board. There is a pad connecting to ground; solder a piece of wire from the metal case to this pad.

Many input voltage capabilities. No matter what you choose, I'd recommend a 7-9VDC supply; nothing more than 12VDC. Keep in mind that if you use the bridge rectifier input there are 2 diode drops. You can bolt the voltage regulator to the board for a little heatsinking though I don't think it's needed.

There's a small "proto" area with +5 and ground available.

Let me know if anything looks squirrely.

Have fun.

EDIT: I used "cutePDF" to generate the PDF of the PCB. I don't know why but the pads look a little "odd". They really aren't like that in the Gerbers...
