Questions
How big is the Device PCB?
It measures 75.6 × 142.2 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Device use?
53 parts, built around the ESP32-S2-SOLO-N8, SC189ZSKTRT, CD74HC154M96 and NHD-C12832A1Z-FSW-FBW-3V3. 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 Device KiCad files?
From the turtlebasket/pocket-operator repository on GitHub, at the commit this page was made from: the board is device/device.kicad_pcb and its schematic device/device.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Device design in my own project?
Its repository states no licence, so its author keeps all rights: ask turtlebasket before reusing the design.
