Questions
How big is the Catawba PCB?
It measures 110 × 70 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Catawba use?
31 parts, built around the ATSAMD21G18A-AU and ADXL326BCPZ-RL7. 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 Catawba KiCad files?
From the ARTS-Laboratory/Edge-Computing-Power-Management-Development-Kit repository on GitHub, at the commit this page was made from: the board is hardware/Catawba/v0.1.2/v0.1.2.kicad_pcb and its schematic hardware/Catawba/v0.1.0/power.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Catawba design in my own project?
Its repository publishes it under the CC-BY-SA-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).
