Questions
How big is the Kp ledsuit PCB?
It measures 50 × 50 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Kp ledsuit use?
75 parts, built around the MP2359DJ-LF-Z, SK9822, LSM6DS3 and USBLC6-2P6. 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 Kp ledsuit KiCad files?
From the plugz/kp_ledsuit repository on GitHub, at the commit this page was made from: the board is kp_ledsuit.kicad_pcb and its schematic kp_ledsuit.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Kp ledsuit design in my own project?
Its repository states no licence, so its author keeps all rights: ask plugz before reusing the design.
