Adjustable USB Power Supply Module

VELAUKGOODS DIY ELECTRONICS SERIES

Dial In The Voltage Your Project Actually Needs

A compact adjustable USB power module with digital voltage feedback, designed for prototyping, diagnostics, learning projects and low-power electronics testing.

LESS GUESSWORK ON THE BENCH

🔧 Different Project, Different Voltage?

Fixed-voltage adapters can make small electronics testing unnecessarily complicated. This adjustable module gives you a compact way to tune the output for compatible low-power projects and confirm the setting directly on the built-in display.

⚡ Adjustable Power Without A Full Bench Supply

Connect a compatible USB or Type-C power source, adjust the output with the tuning control, and use the digital display to confirm the voltage before connecting your project.

FROM UNPOWERED TO READY TO TEST

⚡ Give Your Prototype The Voltage It Needs

Instead of switching between several fixed adapters, tune one compatible module to the required setting and move from setup to powered testing more efficiently.

SEE THE SETTING BEFORE YOU CONNECT

📟 Clear Digital Feedback Reduces Guesswork

The integrated display makes voltage changes visible immediately, helping you verify the setting before connecting compatible electronic devices or test circuits.

REPEATABLE BENCH SETUPS

🔄 Adjust, Confirm, Test Again

Adjustable regulation and visible voltage feedback make it easier to recreate similar test conditions when moving between prototype revisions or repeating basic diagnostics.

🔧 Compact Enough For DIY Builds

At approximately 22 × 64mm, the module takes up little bench or project space, making it practical for temporary setups, learning boards and compact prototypes.

ONE MODULE • MULTIPLE LOW-POWER SCENARIOS

🧪 Made For The Electronics Workbench

Important Use Notes

• Do not connect motors or other high-power equipment that may exceed the module's power limits.
• Confirm output voltage before connecting sensitive electronics.
• Always check input/output polarity before powering the circuit.
• Keep total load power within the specified limits.
• Avoid short circuits between exposed contacts.
• Disconnect power before changing wiring or modifying the test setup.
• Use only in dry environments and keep conductive objects away from the exposed PCB.

ADJUST • CONFIRM • TEST

Spend Less Time Swapping Power Supplies

Keep a compact adjustable module on your electronics bench for the low-power projects that need a different voltage from one test to the next.
