Questions
How big is the BREAD slice v2 PCB?
It measures 100 × 79 mm and has 2 copper layers, 1.6 mm thick.
What parts does the BREAD slice v2 use?
39 parts, built around the MCP3208-BI/P and 10018783-10200TLF. 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 BREAD slice v2 KiCad files?
From the OSHE-Github/Smart-BREAD repository on GitHub, at the commit this page was made from: the board is Loaf/PCB/PLC_Input_Slice/_restore_backup_2026-10-16T11-26-48-408/BREAD_slice_v2.kicad_pcb and its schematic Loaf/PCB/5V4A VRM Module/VRM Module.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the BREAD slice v2 design in my own project?
Its repository states no licence, so its author keeps all rights: ask OSHE-Github before reusing the design.
