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.

OpenDropV4: common questions
What microcontroller does the OpenDropV4 use?
The OpenDropV4 is built around the SAMD21G18B-A changed from SAML21, from the Microchip SAM family.
How big is the OpenDropV4 PCB?
The OpenDropV4 measures 124 × 115.4 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the OpenDropV4?
118 components, from 53 distinct parts. The full bill of materials is listed on this page.
Where can I download the OpenDropV4 design files?
From the GaudiLabs/OpenDrop repository on GitHub, which has the KiCad layout; the links under Design files point to each one.
Can I use the OpenDropV4 design in my own project?
