Questions
How big is the Espbb PCB?
It measures 22.9 × 30.7 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Espbb use?
12 parts, built around the ESP-12E 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 Espbb KiCad files?
From the techinc/espbb12e repository on GitHub, at the commit this page was made from: the board is espbb.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Espbb design in my own project?
Its repository states no licence, so its author keeps all rights: ask techinc before reusing the design.
