Questions
How big is the Esp8266writer PCB?
It measures 50 × 50 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Esp8266writer use?
29 parts, built around the CP2104EK, LM1117-3.3 and BSS138. 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 Esp8266writer KiCad files?
From the taki-d/endo_lighting_controller repository on GitHub, at the commit this page was made from: the board is esp8266writer/esp8266writer.kicad_pcb and its schematic esp8266writer/esp8266writer.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Esp8266writer design in my own project?
Its repository states no licence, so its author keeps all rights: ask taki-d before reusing the design.
