README
README.mdMutable Instruments' Eurorack Modules.
Forked from pichenettes' version and identical except:
- Eagle brd and sch files converted to XML (making possible import into KiCad)
- For some modules, KiCad versions have been added
I have updated this repo to reflect upstream changes, but I am no longer able to convert the Eagle files, so not all are available as XML.

Questions
How big is the Braids v50 PCB?
It measures 78.7 × 106.7 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Braids v50 use?
120 parts, built around the STM32F103CBT6, MCP3204-CI/P, MCP6004-E/P and TL072. 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 Braids v50 KiCad files?
From the jonstapleton/mutable_eurorack repository on GitHub, at the commit this page was made from: the board is braids/hardware_design/pcb/KiCad/braids_v50.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Braids v50 design in my own project?
Its repository states no licence, so its author keeps all rights: ask jonstapleton before reusing the design.
