Electrical engineering

✅ Why this step powers your product—literally and strategically

If your product plugs in, lights up, senses, or communicates—it needs electrical engineering.

This step is about designing the circuitry, logic, and systems that bring your product to life. Whether it’s a simple LED controller or a full embedded system, electrical engineering connects functionality with feasibility. Done well, it ensures power, safety, and reliability from first prototype to production.

📘 What you’ll define and design

  • The circuit architecture and components that deliver your product’s functions
  • How power is managed, distributed, and protected
  • How signals, sensors, and interfaces work together
  • How the system can be built, tested, and supported in real-world conditions

🛠️ Tools and methods

  • Schematic Capture & Simulation

    Design and test logic paths, voltage drops, and current limits.

  • PCB Layout (2-layer or more)

    Design boards that meet electrical, thermal, and EMI/EMC requirements.

  • BoM (Bill of Materials)

    List all electrical components with sourcing, specs, and alternates.

  • Power Budget Sheet

    Calculate consumption across modes and components.

  • Design for Debug

    Add test points, modularity, and fallback modes from day one.

⚠️ Mistakes to avoid

  • Overlooking system-level impacts. Heat, interference, mechanical fit, and UI all affect electrical design.
  • Copying without understanding. Reuse is great—unless it breaks under different loads or code.
  • Ignoring firmware early. Embedded code affects pin selection, power-up timing, and behaviour.
  • Skipping layout review. Routing, grounding, clearance—all critical to board performance.

💡 From the circuit bench

“The sensor worked fine in lab tests, but failed once inside the enclosure. EMI from a motor line we hadn’t isolated. Lesson learned.”

– Embedded Systems Engineer, Smart Mobility Team

💡 Use real-world mockups—wire up early prototypes in intended housings, with intended power supplies, to catch integration bugs fast.

✍️ Quick self-check

  • Do we have a working system diagram with all components identified?
  • Have we tested the architecture with breadboards or dev kits?
  • Are power, signal, and safety paths confirmed in both design and reality?
  • Can we build a prototype or board that others can test and replicate?
