So I got out some CF cards and noticed something odd about this one. Do you see the weirdness?
They're definitely not USB.

Flip it over, bend it in half, and now you can plug your SD card right into a USB port pic.twitter.com/jeBefP2xU1

This is a normal CF card in most cases, you can use it in normal CF card readers and such
1. it only works with jumpSHOT CF cards with the "USB enabled" logo on them
2. THERE'S NOTHING INSIDE IT
But that's two microcontrollers. Why not save money and just have one?
