PCB Version

Here  is a completed PCB version that I have made .. the cost of this should not be huge (assuming you already have MEGA Arduino board.

Basic parts:

• • PCB

  • 40pin ZIF socket

  • 4 leds

  • 4 resistors(4.7k)

  • few strips of IDC pins

  • 1 small surface mount push button

That is basically all you need if you have MEGA board. With this setup you be able to program DS1249/50/70 NVRam chips.

I will include an update Arduino file to be able to program the chips. Also should have a Windows app to let you do that .. still in final stages .. Will post as soon as I am happy with its operation.
