Questions
How big is the Leaflet PCB?
It measures 38.1 × 44.7 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Leaflet use?
32 parts, built around the IP4220CZ6, NTZD3155C and BLM21PG221SH1. 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 Leaflet KiCad files?
From the XANi/ee repository on GitHub, at the commit this page was made from: the board is leaflet/pcb/leaflet.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Leaflet design in my own project?
Its repository states no licence, so its author keeps all rights: ask XANi before reusing the design.
