Plans for my modular synthesizer

Plans for my modular synthesizer, named Cynthia.

I have split the modules into folders with numbered names. These numbers only correspond to the order that I included them into this project. Every project should at least contain: - a README.md with more information about the module - schematics for the schematics, made in KiCAD - stripboard for the design of the stripboard (you don't need this if you order proper PCBs). I use DIY Layout Creator for this. - panel for the Kosmo-format (20cm height) panels. I use a custom template for OpenSCAD which can be found in lib/kosmo.scad. On linux, you…

07 io: common questions

How big is the 07 io PCB?

The 07 io measures 50 × 50 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the 07 io?

25 components, from 7 distinct parts. The full bill of materials is listed on this page.

Where can I download the 07 io design files?

From the bmurauer/cynthia repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the 07 io design in my own project?

The repository has no license, so all rights stay with bmurauer. Use it as a reference, and ask the author before reusing the design.
