Questions
How big is the Garnet PCB?
It measures 165 × 50 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Garnet use?
131 parts, built around the ESP32-S3-MINI-1U-N8, L6385ED, MCP33141D-10-E/MS and LM321. 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 Garnet KiCad files?
From the Ti-g/AURCmainboard repository on GitHub, at the commit this page was made from: the board is garnet_hardware/garnet.kicad_pcb and its schematic garnet_hardware/BMS.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Garnet design in my own project?
Its repository states no licence, so its author keeps all rights: ask Ti-g before reusing the design.
