Questions
How big is the Daughter board PCB?
It measures 38.5 × 28 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Daughter board use?
5 parts, built around the MAX31855EASA+T. 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 Daughter board KiCad files?
From the mguentner/gaggia-cortex repository on GitHub, at the commit this page was made from: the board is daughter_board/board.kicad_pcb and its schematic daughter_board/board.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Daughter board design in my own project?
Its repository states no licence, so its author keeps all rights: ask mguentner before reusing the design.
