Micro alimentation
sofia-mabrouk/microphone_projectThis end-of-semester project is essentially to make a microphone (with karaoke as a potential use). This microphone will contain the capsule, a pre-amp and will be need to be plugged to an amp. You'll find here a directory complete with the composants and their datasheets we're planning to use, the schematics of our PCB and its KiCad files.

Questions
How big is the Micro alimentation PCB?
It measures 50 × 70 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Micro alimentation use?
42 parts, built around the 1N4148WT. 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 Micro alimentation KiCad files?
From the sofia-mabrouk/microphone_project repository on GitHub, at the commit this page was made from: the board is KiCAD/Micro_alimentation.kicad_pcb and its schematic KiCAD/Micro_alimentation.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Micro alimentation design in my own project?
Its repository states no licence, so its author keeps all rights: ask sofia-mabrouk before reusing the design.
