Questions
How big is the Segments PCB?
It measures 101.3 × 108.3 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Segments use?
177 parts, built around the MCP6002-I/P, LM1117-3.3, LM1117-5.0 and MMBT3904. 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 Segments KiCad files?
From the microresearch/allcolours repository on GitHub, at the commit this page was made from: the board is SR_segments/segments_fixed_adc/segments.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Segments design in my own project?
Its repository states no licence, so its author keeps all rights: ask microresearch before reusing the design.
