Questions
How big is the VUmeter PCB?
It measures 99.3 × 28.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the VUmeter use?
14 parts, built around the LM3914N-1. 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 VUmeter KiCad files?
From the Aswinlalks/PCBdesigning repository on GitHub, at the commit this page was made from: the board is VUmeter/VUmeter.kicad_pcb and its schematic CurrentDetector/CurrentDetector.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the VUmeter design in my own project?
Its repository states no licence, so its author keeps all rights: ask Aswinlalks before reusing the design.
