I admit it's been a long time since I've been here... doing a lot of non-AVR projects in the past few years!
It has a CPLD mounted on the backside. It's a little like the Digilent Inc boards, except with a few extra features (mainly breadboard) that make it suitable for classroom. Plus has a simple template so you can use schematic entry without really understanding about PLD devices. There is a video on the Kickstarter Page.
Hope you enjoy it! The documentation is all Creative-Commons (e.g. tutorials), and software in the AVR is open-source, so might be a useful reference for anyone doing something similar.
