Ground planes are done. In the process of Via stitching the layers.

Designing a portable RAM card
- Thread starter techknight
- Start date
All done. ground planes are routed, VIA stitching is done, and then the JTAG header installed. Along with some diagnostic LEDs.
Now is finding a PCB service that can run that board, the traces and vias are kinda tight.

What color do you think I should run the boards with?
Lolol.. ur funny
Hmm. Purple. Sonnet style. Nice that actually doesn't sound bad.
went ahead and asked for a quote for 5 pcs prototyping run, just to gauge an idea what each PCB is going to cost roughly. Then i get a bill of materials together, price of RAM from trag, and then assembly/test labor which at that point I can get a per piece price.
I make a poll to see whos interested in buying, so then I can justify the cost of running the boards.
of course, the PCBs might be cheaper if I order a larger number of them, or if I actually panelized the layout, but eh.. thats alot of work.

Yup, hopefully itll be cheap enough to hold interest. Otherwise i designed it all for nothing haha.
my next goal is to design an asyncronouse memory-mapped I/O PDS card.
So i can read/write specific addresses to read/write the card.
I dont really want to mess with DeclROMs, slot manager, slots, all that jaz that most cards do. Id rather just have simple peripheral cards that are directly addressed via drivers.
The next step toward a ARM co-processor/raspberry pi PDS card.

Well, I got quoted for 5 boards, at $62.50. This is basic green. different colors cost more.
$37 for the boards, and another 25 for shipping from china. sheesh. all the board houses are in china these days. Even imagineering is, which is who I used for our production boards for Major Display LLC.
