Dual ADSR based on AS3310
Kicad project files of a dual ADSR based on two AS3310 components. Part of a modular DIY synth project, other modules are available in other repositories. Likely compatible with a CEM3310.
Used the Audio.lib from https://kicad.github.io/symbols/Audio to extend the Kicad library for the AS3310 component.
Designed to work with +/- 15V, not tested for +/- 12V
The PCB is 9.5 x 5.5 cm and has no PCB-mounting of potmeters, switches, jacks; these are all connected by pin header connectors
Important note: Gate must never be unconnected, so must be either GND (off) or 2.6 to 15V (on), otherwise release will never occur. Applying a negative voltage to the gate will break your AS3310!!!

Questions
How big is the Adsr 1 PCB?
It measures 94.5 × 55 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Adsr 1 use?
54 parts, built around the TL082 and TL084. 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 1 KiCad files?
From the hermflink/3310ADSR repository on GitHub, at the commit this page was made from: the board is adsr 1.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Adsr 1 design in my own project?
Its repository publishes it under the GPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
