:
1. All references in this document to physical orientation of components on the board are made with respect to a component
side view of the board with the prototype area appearing in the bottom of the board.
2. The board is laid out to minimize coupling between the analog and digital sections of the board. To this end, the ground
plane is split with the analog section on the left hand side and a digital plane on the right hand side of the board. The
regulated 3.3V power supply is routed directly to the digital section and is filtered before being routed into the analog
section of the board.
