Questions
How big is the EKG generator PCB?
It measures 80 × 104.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the EKG generator use?
18 parts, built around the LM358P. 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 EKG generator KiCad files?
From the asliwaa/ECG-Simulator repository on GitHub, at the commit this page was made from: the board is kicad_files/EKG_generator.kicad_pcb and its schematic kicad_files/EKG_generator.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the EKG generator design in my own project?
Its repository states no licence, so its author keeps all rights: ask asliwaa before reusing the design.
