Ideias
- Implementar um 555 para que os LEDs pisquem.
- Furo no canto para tornar-se um chaveiro
- Modificar o formato da PCB para que também tenha formato de coração
- Num cenário de fabricação industrial, aproveitar a serigrafia para alguma imagem ou mensagem.

Questions
How big is the Heart PCB?
It measures 50 × 50 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Heart use?
21 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 KiCad files?
From the davimm8/heart-pcb repository on GitHub, at the commit this page was made from: the board is heart.kicad_pcb and its schematic heart.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Heart design in my own project?
Its repository states no licence, so its author keeps all rights: ask davimm8 before reusing the design.
