Questions
How big is the Working checkpoint1 PCB?
It measures 81.3 × 99.1 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Working checkpoint1 use?
103 parts, built around the TL072 and LM13700M. 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 Working checkpoint1 KiCad files?
From the blthree/synth_schematics repository on GitHub, at the commit this page was made from: the board is ripples_import/working_checkpoint1.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Working checkpoint1 design in my own project?
Its repository states no licence, so its author keeps all rights: ask blthree before reusing the design.
