Basically the board is divided into two areas, an 'Electrical Area' and a 'Functional Area'.
In Figure 2-1 the Electrical Area is surrounded in by a red line and the Functional Area is surrounded by a blue line.

2.1.1 Electrical Area

In the center of the Electrical Area a 180 pin SMD pad field is located that any of the F-Series devices can be
assembled to.
On each side of the Device Pad Field a Pin Patch Area is located. In this patch area access is given to
- each pin of the device
- VDD
- VSS
Further more SMD and through hole components can directly be soldered onto the Pin Patch Area to allow simple
networks to be easily built up.
The circuitry available at each pin inside the Pin Patch Area is described in the figure below:
