flabbergast's EAGLE PCB files

Currently, the following PCBs are here:

AVR stick microSD + ATMEL EEPROM shield

A shield for matrixstorm's AVR stick, with micro SD, SOIC-8 (JEDEC) I2C EEPROM landing and a proto area. A more detailed writeup is here.

Fits Sparkfun's microSD socket, a variety of ATMEL (or others') I2C EEPROMs (including crypto chips like ATSHA204, ATAES132 or ATECC108 in SOIC-8 package). One button (also from Sparkfun), one LED. The smaller parts are SMD 1206.

Small UEXT board with microSD and I2C EEPROM

A simple UEXT board, with the same microSD socket from Sparkfun, and a SOIC-8 I2C EEPROM landing. Note that the boards from Olimex with UEXT already have pull-ups on I2C signals, so these are not needed if it should be used with them.
