PCB Rev 1.1 Errata:

• The crystal silkscreen shows it as being rotated 90 degrees from what it should be (at least for the crystals I am using... I am not sure if there are standards on this or not). Be sure to verify which pins on your crystal are supposed to be GND, and which pins on the board are supposed to be GND, and rotate the cystal so that these are aligned.
