Questions
How big is the USB HID Module Hat PCB?
It measures 65 × 56 mm and has 4 copper layers, 1.57 mm thick.
What parts does the USB HID Module Hat use?
34 parts, built around the MAX3535ECWI+T, AZ1117CR-3.3TRG1, CGA5L3X5R1V106K160AB and UCM1C470MCL1GS. 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 USB HID Module Hat KiCad files?
From the Accessibilita/USB-HID-Module-Hat repository on GitHub, at the commit this page was made from: the board is PCB/USB-HID-Module-Hat/USB-HID-Module-Hat.kicad_pcb and its schematic PCB/USB-HID-Module-Hat/Power.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the USB HID Module Hat design in my own project?
Its repository publishes it under the CERN-OHL-S-2.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
