This listing is for a 5A DC-DC adjustable step-down module with a built-in LED voltmeter display.

It comes with 4 brass standoffs, matching nuts, and a heatsink with peel-off tape.

Turn the bronze screw to change output voltage. Clockwise increases, anticlockwise decreases. On first use, you may have to turn it anticlockwise a number of times until the output starts changing.

Features include:

  • LED power indicator.
  • Button to switch the display to show input or output voltage on the LED display.
  • Button to turn the display off.
  • LED to indicate that the display is showing either the input or output voltage.
  • Input voltage: 4 to 38 VDC (do not exceed 38 volts).
  • Output voltage: 1.25 to 36 VDC (adjustable).
  • Output current: 0-5A
  • Output power: 75W
  • Efficiency: Up to 96%
  • A calibration mechanism to ensure the display is perfectly accurate (see below for steps).
Note that the input voltage must be higher than the output voltage.  This is a step-down converter.

Calibration routine - Output voltage
Step 1: Ensure the "OUT" LED is lit, showing the input voltage.
Step 2: Press the rightmost button for more than 2 seconds, then release it.
Step 3: The voltmeter "OUT" LED flashes.
Step 4: Tap the leftmost or rightmost button until the LED display is matching your calibrated readout (for example, your multi-meter).
Step 5: Hold the rightmost button to lock in the completed calibration.

Calibration routine - Input voltage
Step 1: Ensure the "IN" LED is lit, showing the input voltage.
Step 2: Press the rightmost button for more than 2 seconds, then release it.
Step 3: The voltmeter "IN" LED flashes.
Step 4: Tap the leftmost or rightmost button until the LED display is matching your calibrated readout (for example, your desktop DC power source or multi-meter).
Step 5: Hold the rightmost button to lock in the completed calibration.
