Questions
How big is the PicoAWG PCB?
It measures 200 × 130 mm and has 4 copper layers, 1.6 mm thick.
What parts does the PicoAWG use?
370 parts, built around the RP2040, IA0515D, ADA4817-2ACPZ-R7 and AD9106BCPZ. 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 PicoAWG KiCad files?
From the Alberta2514640/EIT-Machine repository on GitHub, at the commit this page was made from: the board is PCB_Design/picoAWG.kicad_pcb and its schematic PCB_Design/analog.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the PicoAWG design in my own project?
Its repository states no licence, so its author keeps all rights: ask Alberta2514640 before reusing the design.
