Well, this just dropped into my lap recently for free:

I have no idea what to do with it. Apparently, it's a whole SoC, with 10 pins with which to make its mark on the world. The official website says it's a "flash programmer", but I've never seen a flash chip that wasn't TSOP, plus, they all have more than 10 pins.
So I guess I'm asking: what does it do? Can I control each pin individually, and kinda use it like an Arduino?
