theres tons of space smiley
move one of the 10pf caps to the other side, where the (cc) is
then put the LED there

i like it a lot, i think it needs to have a 'pin 13' led tho so that people can do the 'blink' test. There's already a resistor so why not? (the resistor should come after the pin, i think...since the diecimila does that.)

nearly done with documentation... and in the shop! i also posted up some examples

good point! i do know that the direct and direct+ are compliant, and i have a year old xport thats v3
http://www.lantronix.com/support/bulletins.html
implies that they've had v03 since at least 2004 and the cheapest ones that mouser carries are v3 so i expect 99% of people who are buying the shield will not have a problem
for the remaining 1% i can also show how to make a quick hack to adapt it (like 6 resistors) smiley
& ill patch it in the next version of the PCB

not sure about the wiports/matchports, i have one but they're quite large and may not fit on a shield

heres the prototypes...so far so good, i have to go thru and test everything now, including all the flow control & GPIO junk smiley-sad

its not nearly as powerful as a wiznet or cs8900a, but maybe is good for basic projects?
i dunno, what do you think?  :-?
Seems like you're on a shield-designing frenzy... :-)


well, yknow once you get the FeCl bath going, you might as well etch a couple boards smiley

i made a very simple xport shield for xports and xport directs (or is it xports direct??) its not nearly as powerful as a wiznet or cs8900a, but maybe is good for basic projects?
i dunno, what do you think?  :-?

I'm trying to decide whether it means "something is wrong" when adding USB multiplies the price of the thing by five.

its a little more complex than that. first off its a double-sided pre-assembled PCB. that adds quite a bit of cost. secondly, its a 4-layer board, which is more expensive to fab & test than a 2-layer. the nano (like the lilypad) is an Arduino, and so they both have to pay a licensing fee (5%-10%). and lastly, paul doesn't factor in a retailers margin.  when you consider -all- of the costs, it is clear how the price ends up at $50!

the nano is good design.

serial ports are designed to cope with 3%+ error with no problems

i have a couple extra beta protoshields.
anybody want to build and play with one of these? send me a PM. thanks! smiley

I think the existence of WW headers solves the stacking issue as far as I'm concerned.

good. glad i made you happy smiley

Here are pictures of what 'stacking' looks like when using wirewrap header
