Questions
How big is the EmbeddedSystemKit PCB?
It measures 123.3 × 61 mm and has 4 copper layers, 1.6 mm thick.
What parts does the EmbeddedSystemKit use?
73 parts, built around the CP2102N-A01-GQFN28R, ESP32-WROOM-32, PCF8574T and AMS1117-3.3. 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 EmbeddedSystemKit KiCad files?
From the bostang/PCBs repository on GitHub, at the commit this page was made from: the board is Embedded System Kit v2/EmbeddedSystemKit.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the EmbeddedSystemKit design in my own project?
Its repository states no licence, so its author keeps all rights: ask bostang before reusing the design.
