Adjustable Buck-Boost DC Module with LCD, 0.5–30V

Set a suitable DC output above or below the input with a buck-boost module. It is for experienced makers powering a matching bench project.

• ✅ Adjust the project voltage — The converter steps a compatible input up or down.
• ✅ Limit the output current — A separate control sets the current threshold.
• ✅ Read the operating values — The LCD shows input/output voltage and load information.
• ✅ Switch the output locally — A button turns the module output on or off.

Set the output before connecting the project

Match the input, output, current and cooling requirements to the load. The 35W natural-cooling figure and higher cooled figure are different operating conditions.

This board is not a complete enclosed power supply or universal battery charger. Battery applications need the correct chemistry-specific control and protection.
