Building on skills developed in the introductory KiCad tutorial, this article will focus on creating custom parts and adding them to a local library, expanding the default libraries to include community repositories, and contributing parts back into the open source ecosystem. The end product will be a MAX31855 K-type thermocouple amplifier which can be used for a huge array of temperature sensing projects.
