Questions
How big is the DashHat PCB?
It measures 65 × 56 mm and has 4 copper layers, 1.6 mm thick.
What parts does the DashHat use?
154 parts, built around the MAX3227IDB, TCAN330D, 74LVC1G80GW and CAT24C256LI. 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 DashHat KiCad files?
From the michaelyoyo/piDashHat repository on GitHub, at the commit this page was made from: the board is dashHat.kicad_pcb and its schematic GPIO.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the DashHat design in my own project?
Its repository states no licence, so its author keeps all rights: ask michaelyoyo before reusing the design.
