Questions
How big is the Alpha spectrometer v1 PCB?
It measures 63.1 × 45 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Alpha spectrometer v1 use?
134 parts, built around the LM2733XMF, LMR50410XDBVR-MS, MAX4477AUA+ and SD4932B. 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 Alpha spectrometer v1 KiCad files?
From the Maniak003/AlphaSpectrometr repository on GitHub, at the commit this page was made from: the board is kicad/alpha-spectrometer_v1/alpha-spectrometer_v1.kicad_pcb and its schematic kicad/alpha-spectrometer-proto/alpha-spectrometer-proto.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Alpha spectrometer v1 design in my own project?
Its repository states no licence, so its author keeps all rights: ask Maniak003 before reusing the design.
