Questions
How big is the Espio PCB?
It measures 77.1 × 82.9 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Espio use?
155 parts, built around the LF50CPT-TR, BZV55-C3V6,115-JSM, 1N5819HW-7-F-01 and 1812L110/33MR. 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 Espio KiCad files?
From the TheLexoPlexx/espio repository on GitHub, at the commit this page was made from: the board is pcb/v2_6/espio.kicad_pcb and its schematic pcb/.old/espio.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Espio design in my own project?
Its repository states no licence, so its author keeps all rights: ask TheLexoPlexx before reusing the design.
