README
README.mdOverview
This repository contains supplementary information and resources for a microfluidic controller platform based on the plfluidic Python module. This is a reviewer copy and contains:
- code for the Python application
- Yocto build files for a custom Linux image
- KiCAD design files for the custom PLRD1 solenoid driver PCB
- oscilloscope waveforms and analysis scripts for the PCB characterization results
- CAD files for the 3D printed enclosure
- a bill-of-materials to replicate the instrument
Other supporting information including a build guide and operation instructions have been submitted with the manuscript.
While under review, minor bugs in the Python application will be addressed and an interface that supports simultaneous pneumatic valve and syringe pump operation will be developed. The published version of the code and supporting information will have a Zenodo DOI.

Questions
How big is the PLRD1 24ChRelayDriver PCB?
It measures 50.4 × 69 mm and has 2 copper layers, 1.6 mm thick.
What parts does the PLRD1 24ChRelayDriver use?
86 parts, built around the FT4222HQ-C, MBR0580, SML-P11UTT86R and PMEG60T20ELRX. 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 PLRD1 24ChRelayDriver KiCad files?
From the robertpuccinelli/microfluidic_controller_reviewer_copy repository on GitHub, at the commit this page was made from: the board is PLRD1 PCB Files/PLRD1_24ChRelayDriver.kicad_pcb and its schematic PLRD1 PCB Files/PLRD1_24ChRelayDriver.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the PLRD1 24ChRelayDriver design in my own project?
Its repository publishes it under the CC-BY-4.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
