This projects aims to find a working solution with a 2-layer PCB without micro-vias for the L2 chip + ULPI USB chip.
The design is made in Eagle 5.8, which can be downloaded from http://www.cadsoftusa.com/
Eagle provides a free license version for non-profit use; (has a limited maximum PCB size, max 2 layers and only one schematic sheet)
DRC is using
min 0.3 mm drill
0.125 mm clearance
0.125 mm min width
0.125 mm min annual ring
All rails/ground has at least
0.2 mm clearance
0.3 mm width

After research a few of the weblog posts on your web site now, and I truly like your method of blogging. I bookmarked it to my bookmark web site record and might be checking again soon. Pls check out my web site as nicely and let me know what you thinks from ged practice test
Test
This is a test post.
File missing in v 0.12
Sorry, the board file is missing in the v 0.12
Will be updated this evening
LDO
Well, at least it started with an A
Since you are using LDO´s I wouldn't be too afraid of EMI, at least regarding EU and FCC compliance.
If some radio receiver is added - then you never know.
I guess filter-free class D stages is much worse.
Placing caps on the backside would make shorter path's between the ground and the rails.
The current isn't so large, and the voltage ripple isn't either.
Amino rather than arduino
Do you mean Amino rather than Arduino? ;-)
The answer is yes by the way, using a modified version of this layout I hope to be able to create an Amino Stamp based around L2. In fact I am already playing around with modifying your design towards that end..

PCB
I'm hoping for Folknology to make a L2 variant of his Arduino.
Myself I am thinking about a better USB Audio Card with the L2 - that could result in a PCB.
Blank PCB's
Are you planning to get some PCB's made?
Outline
I added a 10x8 cm outline in positive space
L2 board already!
Not waiting for Xmos, that's great, and thanks for sharing. The extra speed will be appreciated when I X~link FPGAs especially. The power management and 65nm node marks a significant improvement to
the L series. I wounder about what may be appended when the G series go's 65nm. It would be nice if
when a new chip is released a board with said chip could be issued, too. In the meantime we'll just have to roll our own.
Placement with free version of Eagle
Quick tip re free version of Eagle..
In order to allow users of the free version to be able to easily manipulate this file you will need to move all of the components (and dimensions) into the positive co-ordinate space, whilst also making sure it remains within the max size limits of that version.
