Questions
How big is the Chelizi PCB?
It measures 448 × 144 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Chelizi use?
237 parts, built around the E73-2G4M08S1C, BL8064CB3TR33, HX4054A and PCA9535PW. 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 Chelizi KiCad files?
From the beeender/chelizi repository on GitHub, at the commit this page was made from: the board is chelizi.kicad_pcb and its schematic chelizi.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Chelizi design in my own project?
Its repository states no licence, so its author keeps all rights: ask beeender before reusing the design.
