Questions
How big is the Rools core PCB?
It measures 102 × 108 mm and has 4 copper layers, 1.57 mm thick.
What parts does the Rools core use?
148 parts, built around the OPA4171AID, MCP6004-E/P, AP2112K-3.3 and LM393. 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 Rools core KiCad files?
From the amorwilliams/Rools repository on GitHub, at the commit this page was made from: the board is hardware/kicad/rools-core/rools-core.kicad_pcb and its schematic hardware/kicad/rools-core/rools-core.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Rools core design in my own project?
Its repository states no licence, so its author keeps all rights: ask amorwilliams before reusing the design.
