README
README.mdsamdNano+
The samdNano+ is based on the Arduino Nano board. The format was extended to allow for more pins to be broken out. It uses the powerful SAMD21G18A chip that is significantly faster and more powerful than the Arduino Nano. It boasts extra pins just for SPI and I2C, while additionally the option to disable LEDs and the power regulator for ultra-low power performance.
License
samdNano+ is licensed under the CERN Open Hardware Licence Version 2 - Strongly Reciprocal to allow to modify it and make their own.

Questions
How big is the SamdNano PCB?
It measures 51.2 × 19.1 mm and has 2 copper layers, 1.6 mm thick.
What parts does the SamdNano use?
34 parts, built around the ATSAMD21G18A-AU and AMS1117-3.3. 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 SamdNano KiCad files?
From the crnicholson/samdNano repository on GitHub, at the commit this page was made from: the board is samdNano.kicad_pcb and its schematic samdNano.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the SamdNano design in my own project?
Its repository publishes it under the CERN-OHL-S-2.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
