Questions
How big is the E32wamb PCB?
It measures 50 × 37 mm and has 2 copper layers, 1.6 mm thick.
What parts does the E32wamb use?
34 parts, built around the AP63203WU, AO3400, TS-1187A-B-A-B and WS2812B. 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 E32wamb KiCad files?
From the wejn/e32wamb-pcb repository on GitHub, at the commit this page was made from: the board is project/e32wamb.kicad_pcb and its schematic project/e32wamb.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the E32wamb design in my own project?
Its repository states no licence, so its author keeps all rights: ask wejn before reusing the design.
