Bem-vindo(a) ao meu repositório de projetos de hardware!
Este espaço é dedicado à documentação e partilha dos meus projetos de Placas de Circuito Impresso (PCBs) e desenvolvimento de sistemas embebidos, abrangendo todo o fluxo de engenharia EDA: desde a conceção do esquemático elétrico, seleção de componentes, cálculo e roteamento de pistas, até à validação por DRC e geração dos ficheiros industriais de fabrico.
🛠️ Ferramentas & Metodologia de Trabalho
- Software EDA: KiCad
- Dimensionamento Técnico: Norma IPC-2221 (Cálculos de largura de pistas, capacidade de corrente e gestão térmica)
- Regras de Desenho: DFM (Design for Manufacturability) com validação estrita por ERC/DRC (Zero Erros / Zero Desconexões)
- Documentação & Produção: Emissão de relatórios técnicos e geração de ficheiros standard industriais (Gerber RS-274X / Excellon Drill)
📂 Organização do Repositório
Os ficheiros e documentação deste projeto encontram-se distribuídos pelas seguintes pastas:
- 📁
/Hardware— Ficheiros de projeto e esquemático elétrico do KiCad (.kicad_pcb,.kicad_sch). - 📁
/gerbers— Pacote compactado (.zip) com os ficheiros de fabrico Gerber e Drill prontos para produção. - 📁

Questions
How big is the Smart Industrial Gateway PCB?
It measures 60 × 60 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Smart Industrial Gateway use?
22 parts, built around the CH340C, ESP32-WROOM-32 and AMS1117-3.3. 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 Smart Industrial Gateway KiCad files?
From the potuin/pcbs_projetos repository on GitHub, at the commit this page was made from: the board is Hardware/Smart Industrial Gateway.kicad_pcb and its schematic Hardware/Smart Industrial Gateway.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Smart Industrial Gateway design in my own project?
Its repository states no licence, so its author keeps all rights: ask potuin before reusing the design.
