From the post
An old request. It is a biggie but I'm sure someone will tackle this anyway *cough, cough...Chris*.;-)
Schematic
This is a board layout, a drawing of where each part goes, and the post may link the schematic it was drawn from. Open the layout at Dirtbox Layouts. No KiCad fragment has been drawn for this circuit yet.
