Questions
How big is the Lab1-v2 PCB?
It measures 65 × 56 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Lab1-v2 use?
13 parts, built around the HC-SR04, TCRT5000 and GP2S700HCP. 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 Lab1-v2 KiCad files?
From the Astrak00/Spring25 repository on GitHub, at the commit this page was made from: the board is CS437 - IoT/lab1-v2/lab1-v2/lab1-v2.kicad_pcb and its schematic CS437 - IoT/lab1-v2/lab1-v2/lab1-v2.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Lab1-v2 design in my own project?
Its repository states no licence, so its author keeps all rights: ask Astrak00 before reusing the design.
