Questions
How big is the M09A GroupG pcb PCB?
It measures 100 × 100 mm and has 4 copper layers, 1.6 mm thick.
What parts does the M09A GroupG pcb use?
193 parts, built around the ESP32-S3-WROOM-1-N8R8, TAS5805MPWP, TPS61089RNRR and DW01A. 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 M09A GroupG pcb KiCad files?
From the Jackson-Andrews/Sound-Helmet-PCB repository on GitHub, at the commit this page was made from: the board is Sound-Helmet-pcb/projectPcb/M09A_GroupG_pcb.kicad_pcb and its schematic Sound-Helmet-pcb/projectPcb/M09A_GroupG_pcb.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the M09A GroupG pcb design in my own project?
Its repository states no licence, so its author keeps all rights: ask Jackson-Andrews before reusing the design.
