4. Safety Check: Ensure no short circuits before powering on.

Frequently Asked Questions (FAQs)

• Q: Can this module boost voltage?
  A: No, it’s a step-down (buck) converter only.
• Q: Why is my module overheating?
  A: Exceeding 3A or poor ventilation causes heat. Use a heatsink.
• Q: Is the output voltage stable under load?
  A: Yes, with ±0.5% load regulation.
• Q: Does Bigyan Project offer warranty?
  A: Yes! Contact us for support.

Challenges and Considerations

• ⚠️ Heat Dissipation: Requires heatsinks for high-current (3A) applications.
