Speaking of labels, we found a few goodies for enterprising devs:

These empty pads look like they're ready to accept some ZIFs, possibly for extra USB devices.

Unused USB 3.0 connector

Cute li'l empty 5-pin socket (possibly a header for another USB 2.0 port)

Similarly empty 10-pin header (possibly a JTAG port for the XMEGA MCU)

More empty solder pads!

Hardware doesn't have the same open source licensing guidelines that software has. In order to follow a framework that promotes development beyond the code, Razer modeled their Module Development Kit platform after Google's Project Ara.
