Questions
How big is the Esp8bit PCB?
It measures 85.9 × 50 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Esp8bit use?
24 parts, built around the LM386. 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 Esp8bit KiCad files?
From the jscrane/esp8bit repository on GitHub, at the commit this page was made from: the board is esp8bit.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Esp8bit design in my own project?
Its repository publishes it under the Apache-2.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
