Questions
How big is the Pressuretransducers PCB?
It measures 85 × 76 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Pressuretransducers use?
183 parts, built around the LAN8742AI-CZ-TR, TJA1462ATK/0Z, ADS131M08IRSNR and AP2112K-3.3TRG1. 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 Pressuretransducers KiCad files?
From the npgo22/APRL-Electrical repository on GitHub, at the commit this page was made from: the board is ali/v2/pressuretransducers/pressuretransducers.kicad_pcb and its schematic ali/v1/ThermoBoard/ThermoBoard.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Pressuretransducers design in my own project?
Its repository states no licence, so its author keeps all rights: ask npgo22 before reusing the design.
