Product features:
DROK buck voltage converter input voltage range is DC 5V-23V,
recommend the use of within 20V; output voltage range is DC 0-16.5V,
can be continuously adjustable; peak output current is 3A, recommend
the use of within 2A.
UNIQUE DESIGN: our voltreducer is with two amazing button for
adjusting the voltage, one for decreasing voltage, the other for increasing
voltage, convenient to adjust voltage.
LCD DISPLAY: the step-down regulator circuit is designed with large
LCD display, can be clearly read the voltage and current at the same time.
BEST QUALITY: this power supply module adopted imported MP2304
chip; 95% conversion efficiency, +/- 1% accuracy, low heat generated.
EASY INSTALLATION: designed with terminal blocks, you can connect
the input and output by using a screw, needn't any soldering work.

The module has calibration function, no need to worry ifthe measurement
is not accurate.
If you find that the measuring values are not accurate or values are
stuck, and left and right buttons can not adjust voltage, please do as
follow: Calibration method: First, in the case of power off, press and
hold the left button and access to power, then the display starts flashing,
release the button.
Next, measure the output voltage with a multimeter and press the left
and right button to adjust the value until the multimeter displays close
to 5V, such as 4.98V, 5.02V. Finally, access to power, then the calibration
is complete. Error can be less than 0.04V, if the error is larger, you can
try again.
Package included: Buck Converter 12v to 5v
