Questions
How big is the Runtime Testor PCB?
It measures 61 × 24.4 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Runtime Testor use?
38 parts, built around the STM32F103C8T6, ESP8266EX and AMS1117-3.3. 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 Runtime Testor KiCad files?
From the ENG-EDISON/Sunking_PCBA_Projects repository on GitHub, at the commit this page was made from: the board is Runtime Testor/Runtime_Testor/Runtime_Testor.kicad_pcb and its schematic Backups/Runtime_Tester/Runtime_Tester/Rntime_Tester.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Runtime Testor design in my own project?
Its repository states no licence, so its author keeps all rights: ask ENG-EDISON before reusing the design.
