Questions

How big is the Leaf PCB?

It measures 49.8 × 49.7 mm and has 6 copper layers, 1.2 mm thick.

What parts does the Leaf use?

290 parts, built around the RK809-2, ESD9B5.0ST5G and SKSGPAE010. 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 Leaf KiCad files?

From the sprhawk/leaf-rv1126 repository on GitHub, at the commit this page was made from: the board is leaf.kicad_pcb and its schematic DDR.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the Leaf design in my own project?

Its repository states no licence, so its author keeps all rights: ask sprhawk before reusing the design.
