Questions
How big is the Lesson-5.1 PCB?
It measures 26.6 × 23.3 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Lesson-5.1 use?
25 parts, built around the ESP32-C3 and AP2112K-3.3. 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 Lesson-5.1 KiCad files?
From the Sashkoiv/EMB2_KiCad repository on GitHub, at the commit this page was made from: the board is Lesson-5.1.kicad_pcb and its schematic Lesson-5.1.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Lesson-5.1 design in my own project?
Its repository states no licence, so its author keeps all rights: ask Sashkoiv before reusing the design.
