Questions
How big is the Light sensor design PCB?
It measures 29.5 × 35.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Light sensor design use?
10 parts, built around the BC547. 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 Light sensor design KiCad files?
From the optimusprime1221/Light-Sensor repository on GitHub, at the commit this page was made from: the board is light_sensor_design.kicad_pcb and its schematic light_sensor_design.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Light sensor design design in my own project?
Its repository states no licence, so its author keeps all rights: ask optimusprime1221 before reusing the design.
