New to Arduino, don't know what board I have.

Hi!

I'm a musician who has recently started gathering interest in the world of programing. A friend of mine gave me a board to work with but I have no idea what it is or what I can and cannot do with it. The chip reads MEGA32U4 and is really small. Any suggestion would be thanked.

We’re going to need more than the processor model. Do you have the means to take a digital photograph of the board?

Does it resemble either of these?

Yes! it is exactly the Teensy 2.0. Thanks for the help!

So, I'm guessing that I need Teensyduino to program it?

Teensyduino is a good place to start.
