Questions

How big is the Spectrometer Tang PCB?

It measures 75 × 57.5 mm and has 2 copper layers, 1.6 mm thick.

What parts does the Spectrometer Tang use?

61 parts, built around the ST662ABD-TR, 74HC04D and XC6206P302MR. 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 Spectrometer Tang KiCad files?

From the gaoyichuan/Spectrometer_Tang repository on GitHub, at the commit this page was made from: the board is hardware/Spectrometer_Tang.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.

Can I use the Spectrometer Tang design in my own project?

Its repository states no licence, so its author keeps all rights: ask gaoyichuan before reusing the design.
