Questions
How big is the Zelenin HW12-prj PCB?
It measures 143 × 49.4 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Zelenin HW12-prj use?
71 parts, built around the MC34063AP, 74HC595, NE555P and BC337. 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 Zelenin HW12-prj KiCad files?
From the molnija3d/m3d_mipt_study repository on GitHub, at the commit this page was made from: the board is Electronics_Base/HW_12/zelenin-HW12-prj/zelenin-HW12-prj.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Zelenin HW12-prj design in my own project?
Its repository states no licence, so its author keeps all rights: ask molnija3d before reusing the design.
