Questions
How big is the Picones PCB?
It measures 100.1 × 112 mm and has 6 copper layers, 1.2 mm thick.
What parts does the Picones use?
59 parts, built around the ATTINY13A-PU, TXS0108EPW, TMUX1574PW and 74HC595. 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 Picones KiCad files?
From the WiiMake/picones repository on GitHub, at the commit this page was made from: the board is hardware/picones.kicad_pcb and its schematic hardware/picones.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Picones design in my own project?
Its repository states no licence, so its author keeps all rights: ask WiiMake before reusing the design.
