Questions
How big is the MicroDroplet PCB?
It measures 86.4 × 96.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the MicroDroplet use?
104 parts, built around the MCP6002-I/P, MAX1771ESA, ES2F and SS-12F44-G5. 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 MicroDroplet KiCad files?
From the CGrassin/microdroplet_electrowetting repository on GitHub, at the commit this page was made from: the board is MicroDroplet_PCB/MicroDroplet.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the MicroDroplet 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).
