Aside from the lens and sensor in front, the left arm of the glasses is where you'll find the rest of the camera. On the bottom is a microSD card slot that supports cards up to 32GB and a nonstandard eight-pin Micro-USB port, different from the type you'll find on most mobile devices. There is a small flap that covers the port as well as a tiny reset button; after the first time I lifted the flap, it never fit flush with the body again and frequently popped out of place.
