Questions
How big is the Toolset Hotswap Board PCB?
It measures 58.1 × 45 mm and has 2 copper layers, 1.67 mm thick.
What parts does the Toolset Hotswap Board use?
61 parts, built around the TPS2491DGSR, BSS138, BAV70 and NUP2301MW6. 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 Toolset Hotswap Board KiCad files?
From the techy-robot/Meteoroid repository on GitHub, at the commit this page was made from: the board is KiCad/Toolset Hotswap Board/Toolset Hotswap Board.kicad_pcb and its schematic KiCad/Klipper-To-CACKLE/Connectors.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Toolset Hotswap Board design in my own project?
Its repository states no licence, so its author keeps all rights: ask techy-robot before reusing the design.
