Board studio

Write what the board is — parts, rails, what connects to what — and Vision's placer and router lay it out. Press a button on the board and the LED answers. When it checks clear, save it to a project (its fab zip lands beside it) or download the zip for the PCB service. This one starts from a sample — change anything.
