Questions
How big is the Brightness Meter PCB?
It measures 78.9 × 82 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Brightness Meter use?
154 parts, built around the HX710B, INA128U, MCP6002-I/P and TPS54331D. 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 Brightness Meter KiCad files?
From the DONGKHOA/Brightness-Meter repository on GitHub, at the commit this page was made from: the board is Hardware/Brightness_Meter/Brightness_Meter.kicad_pcb and its schematic Hardware/Brightness_Meter/Brightness_Meter.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Brightness Meter design in my own project?
Its repository states no licence, so its author keeps all rights: ask DONGKHOA before reusing the design.
