Questions

How big is the Heart led pcb PCB?

It measures 111.3 × 103 mm and has 2 copper layers, 1.6 mm thick.

What parts does the Heart led pcb use?

23 parts. 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 Heart led pcb KiCad files?

From the Kavya021109/Heart-PCB repository on GitHub, at the commit this page was made from: the board is heart_led_pcb.kicad_pcb and its schematic heart_led_pcb.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the Heart led pcb design in my own project?

Its repository states no licence, so its author keeps all rights: ask Kavya021109 before reusing the design.
