Update: fabbed boards are in. Waiting on parts.
I thought I’d take a shot at making my own AVR board. I wanted to see if I could fit four of them panelized on a 5cm x 5cm board, but still keep all of the features and access to the pins. This board is about the same area as a “Teensy 2.0”, but with more features. I chose an ATMega32u4, because it has USB built-in. I succeeded in cramming the design into the space, even preferring larger components for easier assembly. It even has a 3v3 regulator. The one thing I ended up cutting was a reset button, which I seem to never use anyway. The pins are accessible to wire one up if needed. My plan is to use female headers, like the BeagleBone does, so there’s no need to be breadboard compatible.
I dub thee Lepton. Now I’ve just got to get some fabbed and try them out.
