Questions
How big is the Leditaulu PCB?
It measures 56 × 78 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Leditaulu use?
51 parts, built around the ESP-12E, NRF24L01P-R and LD1086DT. 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 Leditaulu KiCad files?
From the jvsalo/leditaulu repository on GitHub, at the commit this page was made from: the board is kicad/leditaulu.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Leditaulu 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).
