Questions
What parts does the Medzik TDA2005 Amplifier use?
40 parts, built around the TDA2005. 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 Medzik TDA2005 Amplifier KiCad files?
From the jonsag/miscPCBs repository on GitHub, at the commit this page was made from: the board is medzik TDA2005 Amplifier/KiCad/medzik TDA2005 Amplifier/medzik TDA2005 Amplifier.kicad_pcb and its schematic 2PinLCDBackPack/KiCad/2PinLCDBackPack/2PinLCDBackPack.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Medzik TDA2005 Amplifier design in my own project?
Its repository states no licence, so its author keeps all rights: ask jonsag before reusing the design.
