Question 2:
What power supply approach do you envision for your educational prototype? Consider trade-offs between portability, cost, and efficiency:
- Option 1: Battery powered (e.g., Li-ion or AA batteries) – portable, low power, may require battery management
- Option 2: USB powered – convenient for prototyping, moderate power, easy to integrate
- Option 3: Mains powered (AC/DC converter) – stable power, higher current, increased design complexity
- Option 4: Combination (e.g., battery with mains charging) – flexibility with added complexity
