I ordered 5 as I believe ordering 1 costs $65 and 5 costs $75... If it works I will assemble 2 or 3 of them for myself, to play with the different boards. As for getting them? May have to figure out some 3rd party to make more if there are interested people.

Next step is to put a parts list together. But right now I am playing around with some code :D

Sounds like a nice price from them. May have to try them some time.

Started on parts list: Probably should simply put the XLS file up here. There are things for me to figure out when I order parts for myself, like, I put in pre-cut breakaway headers from Digikey here, which are nice as they save you a little time. But for myself who is only going to do a few, I may just buy bulk ones and cut them myself...

As always should mention that this design and all of the documentation and stuff involved is for my enjoyment and I make no promises that it is good enough for anyone to use for anything... I hope it is, but no promises...

That's a fine BOM Kurt!

A spread sheet would be useful as well.

I think your board will be well received.

Yeah, let them snap their own header strips...

Yep as far as I am concerned. I am simply doing it to have fun and everything is open book/source...

Warning: But again while I have tried to make sure I have everything in the right spot, such that it will properly plug into an Arduino Mega. But until I get them back and build one, well... Since you also have Diptrace, you can also double check as well.

Assuming the design works, it will also be interesting to see if Seed Studio will kit them up, with all of the appropriate parts. I still need to go through my supply of parts and make an order to Digikey and maybe Sparkfun.

Sounds like fun!

I should note, that I did a lot of the design and layout using the Sparkfun Eagle libraries. Diptrace has a conversion facility that allows you to import Eagle files and the like. However there is a bug in the current version, which hopefully they release the fixed version soon. But until then, they have a converted version that you can get from the diptrace forum, in the thread:
http://www.diptrace.com/forum/viewtopic.php?f=5&t=3956

They also have a copy of the converted eagle files from Adafruit up on the thread: http://www.diptrace.com/forum/viewtopic ... 6307#p6307
I have it but have not played with it yet.

What I would like to do sometime is to get as many of the 3D images of the different components, such that for example all of the connectors show up... I have seen a few examples of boards with these type of connectors, but so far I have not seen any files that I can download that contain them...

Again have fun... You may need to change the text on the board to Eric's...

I uploaded an XLS file. Let me know if anyone needs an older file file format...

Kurt

EDIT: I updated to an XLS file. Also changed some of the part numbers to what I ordered. In particular resistors are from cut tape, not from roll... Also diode get replaced to newer one they now stock and I forgot earlier to mention you will need shunts to choose voltages and the like...

If you are asking where I ordered parts from?
I have 5 boards being fabricated at PCBFabexpress.
I ordered most of the parts from Digi-key - I updated the Digi-key part numbers in the spreadsheet.
I ordered the sockets to plug in XBees into from Sparkfun - did not find part number at digi-key but they may have it... Also ordered a couple more xbees.
