Questions
How big is the TECHIN PCB Layout PCB?
It measures 13.5 × 12.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the TECHIN PCB Layout use?
9 parts, built around the BME280 and MIC5376-2.8YC5-TR. 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 TECHIN PCB Layout KiCad files?
From the yplee948-hub/Lab3 repository on GitHub, at the commit this page was made from: the board is TECHIN_PCB_Layout.kicad_pcb and its schematic TECHIN_PCB_Designlab.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the TECHIN PCB Layout design in my own project?
Its repository states no licence, so its author keeps all rights: ask yplee948-hub before reusing the design.
