Power to open source hardware! Thanks for sharing!
So you are using ATMEGA32U4-AU? Isn't sparkfun micro pro using the MU?
I'm interested in working with this processor (AU so I can hand solder). Where did you get the EAGLE part? Just asking.
Oh, I guess you have 3 (or multiples of 3) purple boards for each revision?
What about the micro SD slot? Would you be willing to provide some information?
I am using this one I got from dipmicro on one of my designs. The pins are not very long so I struggled a bit with it while learning (burning stuff of course) SMD soldering:
I usually buy around 100 units (PDIP ATMEGA328P-PU) so I can get better pricing. It's only $3.50 if you buy 100 TQFP 32U4.
BTW, you are on the west coast. Your purple board delivery must be speedy
My current board is too big and I'm cheap so I'm going with iteadstudio.com in China. 2 weeks is a reasonable wait for potential coasters.
It works, but just not perfectly. Any thoughts?
