Before I head out for a holiday break, I wanted to post a teaser of the USB Tester OLED Adapter. I ordered a few PCBs for the first prototype. I was able to breakout all of the unused pins on the Atmega32u4. There are a few that have a via close to the pin instead of a normal header on the edge of the board. I used eagleUp to create the 3D model. You can find it here if you would like to try it: http://eagleup.wordpress.com/. The model is only the PCB, I haven’t had a chance to get the parts working yet.
Happy Holidays! Enjoy!
