Questions
How big is the Pihat PCB?
It measures 53.4 × 76.6 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Pihat use?
50 parts, built around the DS18B20, IQS7222C101QNR, 74LVC2T45DC and IAM-20380. 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 Pihat KiCad files?
From the jcommisso07/rov repository on GitHub, at the commit this page was made from: the board is pihat/pihat.kicad_pcb and its schematic pihat/pihat.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Pihat design in my own project?
Its repository states no licence, so its author keeps all rights: ask jcommisso07 before reusing the design.
