Frequently Asked Questions (FAQ)
1. What is the maximum current output of the LM2596 module?
The module can provide up to 3A, but for continuous load above 2A, a heatsink is recommended.
2. Can this module convert 12V to 5V?
Yes, it is ideal for converting 12V → 5V, 24V → 12V, 9V → 3.3V, etc.
3. How do I adjust the output voltage?
Rotate the blue potentiometer:
Clockwise → Increase voltage
Counterclockwise → Decrease voltage
4. Is the LM2596 module safe for Arduino or ESP32?
Yes, set the output to 5V or 3.3V before connecting.
5. Can it step-up voltage?
No. This is a step-down (buck) converter, not a boost converter.
6. Does it have short-circuit protection?
The LM2596 IC includes thermal shutdown and current limiting, but external protection varies by module design.
