README
README.mdTeensy3.2-example
A verified example PCB based on the Teensy 3.2 schematics. This repository holds the Kicad files to create your own Teensy 3.2 PCB. Design notes can be found on my blog.
I'm a consultant based in Oslo/Norway, so get in touch if you need custom hardware based on Teensy 4.x (Since Teensy 3.x is no longer feasible due to parts shortage)
Pictures of the finished board can be found here.

Questions
How big is the TeensyTest PCB?
It measures 45 × 34 mm and has 2 copper layers, 1.6 mm thick.
What parts does the TeensyTest use?
32 parts, built around the MK20DX256VLH7 and MKL02Z32VFG4. 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 TeensyTest KiCad files?
From the jenschr/Teensy3.2-example repository on GitHub, at the commit this page was made from: the board is TeensyTest/TeensyTest.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the TeensyTest 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).
