Questions
How big is the Charizhard PCB?
It measures 64.7 × 31.4 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Charizhard use?
83 parts, built around the AMS1117-3.3 and ECS-250-18-33Q-DS. 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 Charizhard KiCad files?
From the esp-charizhard/schematic repository on GitHub, at the commit this page was made from: the board is charizhard.kicad_pcb and its schematic charizhard.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Charizhard design in my own project?
Its repository publishes it under the GPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
