Look at all those gold teeth! Yep, there's a lot of connections along the bottom edge of the BBC micro:bit.

They do all kinds of crazy things as you can see in the image below. You can even get a special connector to make using them easier. The big brain of the BBC micro:bit can do a lot of things, and they just wanted to make sure there was a place to get access to them.

Pretty much every program will just use the 5 pads with the big holes. So for now, don't worry about all those other little ones.
