Please note that this project is released with a Contributor Code of Conduct. By participating in this project you agree to abide by its terms.
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 your design folders live 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
When developing your own Polystack boards DO NOT use Chickadee Tech trademarks and follow the MIT license. While not required, please consider open sourcing your designs so others can learn from them. If you do email support@chickadee.tech and we may choose to add your project to the ACD.
You may 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 FCExpansion PCB?
It measures 36 × 36 mm and has 2 copper layers, 1.6 mm thick.
What parts does the FCExpansion use?
13 parts, built around the SN74LVC1G58DCK, AT24CS02-MAHM-T and SN74LVC1G0832DBV. 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 FCExpansion KiCad files?
From the chickadee-tech/polystack repository on GitHub, at the commit this page was made from: the board is tools/start_pcb/templates/polystack_mod/FCExpansion.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the FCExpansion 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).
