Questions
What parts does the Torch4 use?
48 parts, built around the LED2001PHR, BC817, LP2951D and NCP583SQ28. 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 Torch4 KiCad files?
From the Kreyl/Torches repository on GitHub, at the commit this page was made from: the board is Torch4/Torch4_hw/Torch4.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Torch4 design in my own project?
Its repository states no licence, so its author keeps all rights: ask Kreyl before reusing the design.
