My name is Jacob Bendell, and I’m a student at the University of Pennsylvania studying Electrical Engineering. I took this past year off from school to avoid online classes and intern at Amped Innovation, a start-up in the Bay Area that designs and builds solar home systems for people in developing countries. There I worked on a Raspberry Pi project that collects and live-plots voltage, temperature, and battery capacity data. Additionally, I created a Raspberry Pi hat circuit that enables these data collection features.
The folder titled 'pythonscript' contains the files to run the data aquisition and live plotter features.
The folder titled 'kicadhat' contains all the files and libraries for the data logger hat.

Questions
How big is the DataHat PCB?
It measures 56 × 65 mm and has 2 copper layers, 1.6 mm thick.
What parts does the DataHat use?
22 parts, built around the LM2596S-5.0 and MCP3008-I/P. 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 DataHat KiCad files?
From the challengerjdb/RaspberryPiHat-datalogger repository on GitHub, at the commit this page was made from: the board is Kicadhat/DataHat.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the DataHat design in my own project?
Its repository states no licence, so its author keeps all rights: ask challengerjdb before reusing the design.
