Welcome to my PCB projects repository! This space is dedicated to documenting my journey in designing, creating, and improving printed circuit boards (PCBs).
It measures 73 × 41 mm and has 2 copper layers, 1.6 mm thick.
68 parts, built around the RP2040, SC18IS606PWJ, W25Q16JVSSIQ and AP2112K-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.
From the hackclub/reflow repository on GitHub, at the commit this page was made from: the board is pcb/Pcb-Badge/src/badge.kicad_pcb and its schematic pcb/MP3-Player/cad/MP3 Player.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 hackclub before reusing the design.
