Open Source Digital Microfluidics Bio Lab
OpenDrop is a new design for an open source digital microfludics platform for research purposes. The device uses recent electro-wetting technology to control small droplets of liquids. Potential applications are lab on a chip devices for automating processes of digital biology. How ever the present design should also open the technology to other field and allow experimentation to find new applications. Including the field of art, music, games and education.

Questions
How big is the OpenDropV2 PCB?
It measures 100 × 100 mm and has 2 copper layers, 1.6 mm thick.
What parts does the OpenDropV2 use?
232 parts, built around the MCP6002-I/P, MAX1771ESA, BSS138 and ES2F. 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 OpenDropV2 KiCad files?
From the GaudiLabs/OpenDrop repository on GitHub, at the commit this page was made from: the board is OpenDropV2/DesignFiles/OpenDropV2.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the OpenDropV2 design in my own project?
Its repository publishes it under the GPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
