Questions
How big is the Industrial Condition Monitoring Board PCB?
It measures 73.5 × 78 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Industrial Condition Monitoring Board use?
60 parts, built around the LM358, LM339 and BC547. 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 Industrial Condition Monitoring Board KiCad files?
From the Avyukth-ma/Electronics-Projects repository on GitHub, at the commit this page was made from: the board is Industrial-Condition-Monitoring-Board/Industrial Condition Monitoring Board.kicad_pcb and its schematic Dual Rail Power Supply/Dual Rail Power Supply.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Industrial Condition Monitoring Board design in my own project?
Its repository states no licence, so its author keeps all rights: ask Avyukth-ma before reusing the design.
