Questions
How big is the Ledshifter PCB?
It measures 115 × 50 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Ledshifter use?
27 parts, built around the WEMOS D1 MINI. 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 Ledshifter KiCad files?
From the hakierspejs/ledshifter repository on GitHub, at the commit this page was made from: the board is hw/ledshifter.kicad_pcb and its schematic hw/ledshifter.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Ledshifter design in my own project?
Its repository publishes it under the ISC licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
