It measures 177.7 × 44 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Column bus use?
40 parts. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Column bus KiCad files?
From the dangyogi/midi-expression repository on GitHub, at the commit this page was made from: the board is exp_console/PCBs/column-bus/column-bus.kicad_pcb and its schematic exp_console/PCBs/alpha-displays/alpha-displays.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
