Being the only Leo fan makes me feel a little lonely. Come on guys, it can do mouse and keyboard emulation AND it has more I/o than an Uno AND it is cheaper than an Uno. How is that not better?
By Leo I was abbreviating Leonardo. It is a more modern version of the Uno. I has a few extra pins of I/o, can emulate a keyboard or mouse (perfect for pranking unsuspecting co workers) and costs about £2 less. The disadvantages are a slightly different pinout making it incompatible with most shields(but I don't really use shields anyway) and not being able to swap out the chip. I feel it should be more popular than it is, but for some reason, people stick with the Uno. And yes, I do own one, it is currently my only Arduino and I haven't really needed another one. I recomend you buy one instead of your next Uno.
