Questions
How big is the Treadstone32 rev2.0.0 PCB?
It measures 198.8 × 75.8 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Treadstone32 rev2.0.0 use?
90 parts, built around the TLV73333PDBV and PRTR5V0U2X. 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 Treadstone32 rev2.0.0 KiCad files?
From the marksard/treadstone32 repository on GitHub, at the commit this page was made from: the board is pcb/rev2/Treadstone32_rev2.0.0.kicad_pcb and its schematic pcb/rev2/Treadstone32_rev2.0.0.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Treadstone32 rev2.0.0 design in my own project?
Its repository states no licence, so its author keeps all rights: ask marksard before reusing the design.
