Questions
How big is the INSIGHT PCB?
It measures 99.1 × 68.9 mm and has 2 copper layers, 1.6 mm thick.
What parts does the INSIGHT use?
22 parts, built around the ES1. 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 INSIGHT KiCad files?
From the InsightNCSU/PCB repository on GitHub, at the commit this page was made from: the board is INSIGHT.kicad_pcb and its schematic INSIGHT.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the INSIGHT design in my own project?
Its repository states no licence, so its author keeps all rights: ask InsightNCSU before reusing the design.
