Questions
How big is the Electret mic preamp bc547 PCB?
It measures 65.3 × 28.3 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Electret mic preamp bc547 use?
20 parts, built around the BC547C. 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 Electret mic preamp bc547 KiCad files?
From the lpodkalicki/electronics repository on GitHub, at the commit this page was made from: the board is electret_mic_preamp_bc547/electret_mic_preamp_bc547.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Electret mic preamp bc547 design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
