Questions
How big is the Monolith PCB?
It measures 96 × 74.4 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Monolith use?
138 parts, built around the ESP32-S3-WROOM-1-N4, SN65HVD230D, ADS1115IDGS and LMV321. 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 Monolith KiCad files?
From the luftaquila/monolith repository on GitHub, at the commit this page was made from: the board is device/hardware/monolith/monolith.kicad_pcb and its schematic device/hardware/monolith-mini/monolith-mini.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Monolith design in my own project?
Its repository states no licence, so its author keeps all rights: ask luftaquila before reusing the design.
