From the post
Finally got around to tackling this monster... There is a few schematics floating around for this but I ended up using the one from Madbean.
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.
