README
README.mdThe OpenSpectrometer project is a collaborative effort to create freely-available mechanical designs, electronic plans, and software for a USB spectrophotometer. The end goal is an instrument that is inexpensive to build, easy to use, simple to modify, and as accurate and precise as a commercial off-the-shelf unit.
The OpenSpectrometer will integrate commercially-available electronic and optics parts with custom printed circuit boards (PCBs) and an inexpensive a wooden enclosure.
Beyond hardware, the project will develop embedded firmware, and desktop user software, and an online community-driven spectral database.

Questions
How big is the PropellerPCB PCB?
It measures 63.6 × 67.5 mm and has 4 copper layers, 1.6 mm thick.
What parts does the PropellerPCB use?
76 parts, built around the 74LVC126AD, 24LC256-I/P, AT1117-3.3V and FT232HL. 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 PropellerPCB KiCad files?
From the tomkinsc/open-spectrometer repository on GitHub, at the commit this page was made from: the board is pcb-design/propeller_square/propellerPCB.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the PropellerPCB design in my own project?
Its repository states no licence, so its author keeps all rights: ask tomkinsc before reusing the design.
