Questions
How big is the Treeboard PCB?
It measures 85 × 135.6 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Treeboard use?
102 parts, built around the BMD-340-A-R, TXB0104RUTR and SK6812MINI-E. 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 Treeboard KiCad files?
From the compressedfish/treeboard repository on GitHub, at the commit this page was made from: the board is electronic/treeboard.kicad_pcb and its schematic electronic/treeboard.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Treeboard design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
