Prototype Area
The ASC Breakout Board provides multiple areas for prototyping circuits with the ASC. The Through Hole Proto-
type Area (see Sheet 10 of the schematic) is accessible from both the top and bottom side of the board. As shown
in Figure 26, the Through Hole Prototype Area is arranged as a grid on the breakout board. The top three rows pro-
vide ten connections each to the +12V_SW, +5V_SW and +3.3 V voltage rails. The next eight rows provide ten
open connections each – these can be used for mounting and connecting through hole components. The bottom
row provides ten connections to the ground plane of the breakout board.
