Questions
How big is the Assignment 2 PCB?
It measures 81.2 × 99.2 mm and has 2 copper layers, 1.59 mm thick.
What parts does the Assignment 2 use?
53 parts, built around the ESP32-S3-WROOM-1-N8, AL8860MP, TPS54202DDC 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 Assignment 2 KiCad files?
From the dearivia/pcb repository on GitHub, at the commit this page was made from: the board is Assignment 2/Assignment 2.kicad_pcb and its schematic Assignment 2/Assignment 2.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Assignment 2 design in my own project?
Its repository states no licence, so its author keeps all rights: ask dearivia before reusing the design.
