Setup
Components and footprints for PCB parts are not included in this repository. Instead, checkout the chickadee-tech/kicad-libs repository in the same directory that this repository is checked out in. All part definitions should be relative so that they will load correctly.
Pull requests
For fixes please submit a pull request to the original repository. After the pull request is merged, check the Chickadee Tech Active Contributor Discount (ACD) to see if you are eligible for a discount code to use on your next purchase.
Derivatives
If developing your own version of the M0 board please remove all Chickadee Tech trademarks and follow the CC-BY license. While not required, please consider open sourcing your modifications so others can learn from your improvements. If you do email support@chickadee.tech and we may choose to add your project to the ACD.
You may also license the Polystack logo for free by emailing support@chickadee.tech. We'll ask for your gerbers to ensure the design complies with specifications laid out here and provide written permission to use the trademark after compliance has been demonstrated.

Questions
How big is the M0 PCB?
It measures 36 × 36 mm and has 2 copper layers, 1.6 mm thick.
What parts does the M0 use?
54 parts, built around the TLV70233DBV. 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 M0 KiCad files?
From the chickadee-tech/m0 repository on GitHub, at the commit this page was made from: the board is pcb/m0.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the M0 design in my own project?
Its repository publishes it under the CC-BY-4.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
