Questions
How big is the PocKETlab PCB?
It measures 100 × 60 mm and has 4 copper layers, 1.6 mm thick.
What parts does the PocKETlab use?
127 parts, built around the ESP32-S3, LM324, MCP4822-E/P and AP63203WU. 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 PocKETlab KiCad files?
From the bublinak/PocKETlab repository on GitHub, at the commit this page was made from: the board is hardware/PocKETlab.kicad_pcb and its schematic hardware/PocKETlab.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the PocKETlab 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).
