Questions
How big is the Teensy eurorack PCB?
It measures 64.8 × 109.2 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Teensy eurorack use?
52 parts, built around the TEENSY 4.1, AD5754BREZ, AD7606BSTZ and MCP1700-2502E/TT. 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 Teensy eurorack KiCad files?
From the newdigate/teensy-control-voltage repository on GitHub, at the commit this page was made from: the board is hardware/boards/teensy-eurorack.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Teensy eurorack design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
