Next up is the I/O board that plays host to one of the two USB 3.0 ports and the SD card reader.

We love that this Pro has USB 3.0 ports on both sides. At last we resolved the issues of cables that are 12.5" too short and thumb drives, mouse dongles, and USB toys that are a centimeter too wide.

The I/O board also plays host to a Broadcom BCM57100 series Gigabit Ethernet + Memory Card reader controller. The Ethernet controller is accessible through the separately-sold Thunderbolt adapter.
