Questions
How big is the LedTree PCB?
It measures 61.4 × 62.4 mm and has 2 copper layers, 1.6 mm thick.
What parts does the LedTree use?
120 parts, built around the ST1S10PHR, USBLC6-4 and PMEG2020EH. 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 LedTree KiCad files?
From the Kreyl/PresentTimeLedTree repository on GitHub, at the commit this page was made from: the board is LedTree_hw/LedTree.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the LedTree design in my own project?
Its repository states no licence, so its author keeps all rights: ask Kreyl before reusing the design.
