Questions
How big is the Leder PCB?
It measures 102.9 × 105.4 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Leder use?
136 parts, built around the ESP-12E, PCA9685PW, LM1117-3.3 and IRLIZ44N. 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 Leder KiCad files?
From the Enweave/remolight repository on GitHub, at the commit this page was made from: the board is hardware/leder.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Leder design in my own project?
Its repository states no licence, so its author keeps all rights: ask Enweave before reusing the design.
