It's a small dev board for experimenting with the DSPIC33 series of chips. I grabbed these a while ago as I wanted to play with both their analog features as well as the JTAG interface. Although I hear the latter is limiting, I though it'd be fun.
There's a couple of LED's on the RA0 and RA1 lines respectively; these will be handy for testing. i.e.: the normal "hello world" of blinking a couple of them to test the board.
