Questions
How big is the StnStarter PCB?
It measures 52.6 × 50.6 mm and has 2 copper layers, 1.6 mm thick.
What parts does the StnStarter use?
38 parts, built around the 74HC245D, LT1617ES5 and MBR0530. 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 StnStarter KiCad files?
From the zephray/StnStarter repository on GitHub, at the commit this page was made from: the board is hardware/stnstarter.kicad_pcb and its schematic hardware/stnstarter.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the StnStarter design in my own project?
Its repository states no licence, so its author keeps all rights: ask zephray before reusing the design.
