PurpleDrop

This holds the main board electronics design for PurpleDrop, a digital microfluidic device. The design is done in KiCad v5.x.

PurpleDrop is open-source, and you are welcome to build it as-is, or use it as a starting point for your own projects. If you are thinking about building your own PurpleDrop, you are encouraged to reach out first. This project is under active development, and there may be some recent updates or issues not yet reflected here that you should consider. This repository is maintained by Jeff McBride, who can be reached at [email protected].

The latest release of PurpleDrop is v6.4. See ChangeLog.md for history.

Tips for working on this project

BOM Generation

The KiBom plugin is used to generate a BOM file, based on settings in bom.ini.

To re-generate the BOM output:

Add a new BOM plugin in the "Generate BOM" dialog in eeschema, and configure it with this command line: python -m kibom "%I" "%O.csv"

Run the BOM plugin.
