Questions
How big is the Musiq player hardware PCB?
It measures 40.3 × 75.7 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Musiq player hardware use?
64 parts, built around the 74LVC125AD, MAX98357AETE+T, W25Q128JVSIQ and AMS1117-3.3. 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 Musiq player hardware KiCad files?
From the bytecod3/MusiQ-Player repository on GitHub, at the commit this page was made from: the board is hardware/musiq-player-hardware/musiq-player-hardware.kicad_pcb and its schematic hardware/musiq-player-hardware/musiq-player-hardware.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Musiq player hardware design in my own project?
Its repository states no licence, so its author keeps all rights: ask bytecod3 before reusing the design.
