Questions
How big is the ADSR PCB?
It measures 25 × 200 mm and has 2 copper layers, 1.6 mm thick.
What parts does the ADSR use?
52 parts, built around the BC547 and BC557. 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 ADSR KiCad files?
From the telec16/modular-synth repository on GitHub, at the commit this page was made from: the board is ADSR/ADSR.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the ADSR design in my own project?
Its repository states no licence, so its author keeps all rights: ask telec16 before reusing the design.
