README
README.mdThis project is an attempt to make Eurorack modular synthesis affordable and accessible to everyone.
This repository contains open source software and hardware schematics for Eurorack modules which are designed to be assembled easily and cheaply without any technical knowledge. Every module should be able to be assembled for around $20 in about an hour of work, even with limited experience.
To get started, check out some of the links below. Or get in touch! Send me a message at freemodular@gmail.com. Follow my reddit, Etsy shop, or GitHub.
Happy travels on your modular journey!

Questions
How big is the Devboard pcb PCB?
It measures 53.3 × 81.3 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Devboard pcb use?
22 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 Devboard pcb KiCad files?
From the QuinnFreedman/modular repository on GitHub, at the commit this page was made from: the board is modules/devboard/PCBs/devboard_pcb/devboard_pcb.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Devboard pcb design in my own project?
Its repository states no licence, so its author keeps all rights: ask QuinnFreedman before reusing the design.
