Quickstart_PE_shield

Does anyone have a schematic of the Propellerpowered PE shield? I have one that I would like to use but I cannot find the documentation since I crashed an old Hard drive.

Jim,

Do you have a picture of it? It may jog my memory.

Jim,
Does this help?

I have to admit I don't remember that one, and I followed Jeff's stuff for a long time.

I figure you've found this thread?

I'm trying to figure out how one would use one of these boards. It seems like it would be just as easy to plug wires directly into the appropriate hole in the QuickStart header rather than using the shield. I have the impression the shield just moves the QuickStart's header to headers corresponding to pin positions of a DIP chip.

It actually gives you a build area, like a propeller proto board

I always thought this was a better solution. Discontinued at Parallax, but available:

The reason I was asking about this board is I have one and was trying to find what all the prewired connections are.

Such a nice board, I don't want to use it for anything permanent. I do have a couple with M&F headers + small breadboard. The QuickStart is a popular board, with a lot of examples out there, will these proto boards be hard to find some day soon?

Thanks for the input, I finally remembered that the Box in the lower left corner marked V5.0 was for an external coaxial power jack and I was able to ring out all of the necessary connections from there. Now to get my wiring done for sigma delta adc!

Are you using a QuickStart board? If so the QuickStart board includes a pads for delta sigma components. These pads are just above the two holes with the Greek letters delta and sigma.

I've used delta sigma very few times myself. I've read it's best to keep the traces to the delta sigma components short but I've also read forum posts from people claiming delta sigma works fine with longer wires.

I will check it out. Thanks.
