Questions
What parts does the Pico Roaster Board use?
26 parts, built around the IRF740 and MOC3011M. 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 Pico Roaster Board KiCad files?
From the CH-Microsystems/Pico-Roaster-Board repository on GitHub, at the commit this page was made from: the board is pico_roaster_board.kicad_pcb and its schematic pico_roaster_board.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Pico Roaster Board design in my own project?
Its repository states no licence, so its author keeps all rights: ask CH-Microsystems before reusing the design.
