Questions
How big is the PTP Blaškić seminar PCB?
It measures 74.5 × 97 mm and has 2 copper layers, 1.6 mm thick.
What parts does the PTP Blaškić seminar use?
38 parts, built around the ATMEGA328P-PU, DS18B20 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 PTP Blaškić seminar KiCad files?
From the blaskicl/seminar_pcb repository on GitHub, at the commit this page was made from: the board is PTP_Blaškić_seminar.kicad_pcb and its schematic PTP_Blaškić_seminar.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the PTP Blaškić seminar design in my own project?
Its repository states no licence, so its author keeps all rights: ask blaskicl before reusing the design.
