The PCB files for this project. The gerber and other PCBA files are in the production folder.
It measures 77.5 × 85.5 mm and has 2 copper layers, 1.6 mm thick.
69 parts, built around the W25Q128JVSIQ, USBLC6-2P6, ABM8-272-T3 and BAT60JFILM. 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.
From the MAGG4444/BT_Audio_Player_PCB repository on GitHub, at the commit this page was made from: the board is PCB.kicad_pcb and its schematic PCB.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Its repository states no licence, so its author keeps all rights: ask MAGG4444 before reusing the design.
