Questions
How big is the Boardlock PCB?
It measures 101 × 76.2 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Boardlock use?
131 parts, built around the ESP32-S3-WROOM-1-N8, MAX98357AETE+T, MCP1661-E/OT and TPS630701RNMR. 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 Boardlock KiCad files?
From the ECE477Group13/hardware_pcb repository on GitHub, at the commit this page was made from: the board is boardlock/boardlock.kicad_pcb and its schematic boardlock/audio.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Boardlock design in my own project?
Its repository states no licence, so its author keeps all rights: ask ECE477Group13 before reusing the design.
