Questions

How big is the Marta PCB?

It measures 66.5 × 70.8 mm and has 2 copper layers, 1.6 mm thick.

What parts does the Marta use?

29 parts, built around the WS2812B. 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 Marta KiCad files?

From the arturandre/Emo repository on GitHub, at the commit this page was made from: the board is Circuit/EmoRobot/pcb/marta.kicad_pcb and its schematic Circuit/EmoRobot/EmoRobot.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the Marta design in my own project?

Its repository states no licence, so its author keeps all rights: ask arturandre before reusing the design.
