  • 【High Precision】The buck converter consists of 36u thickened circuit boards, high-Q inductance with output LED indicator, and superior solid-state capacitors that can effectively filter out high frequency noise. Suitable for various electronic projects.
  • 【Input Voltage】DC 4V to 38V (input voltage must be 1.5V higher than the output voltage, no boost).
  • 【Output Voltage】DC 1.25V to 36V voltage is continuously adjustable, maximum output current is 5A.
  • 【Mini Size】62*38*14 mm (with potentiometer). 2 sets included.
  • 【Easy to DIY】Connect to power source, using a mini screwdriver to increase or decrease output voltage by adjusting the screw on the blue potentiometer and monitor voltage with multimeter to get the needed voltage, clockwise to step up voltage and counterclockwise to step-down voltage. (Factory default stays a high voltage, you need to contrarotate about 7-15 circles before the voltage starts ramping down, 1 circle means +/- 1V)

Features:
- High power DC-DC step-down module
- Thickened circuit boards
- Advanced solid-state capacitor
- Short circuit and over-temperature protection
- 100% tested, sealed in anti-static packaging

Kindly Note:
1. Input voltage must be 1.5 V higher than the output voltage, no boost
2. Do not reverse the input and output interface
3. Keep output under 5A (or 75W), and use a heat sink when for a long time working

How to Calibrate the Digital Tube Voltmeter
(Optional steps for the person who need a highly accurate voltage value)
1. Short press the left "ON/OFF" button to start up the digital tube voltmeter. Long press(>1s, <4 seconds) the left button to shut down the digital tube voltmeter.
2. Long press(>4 seconds) the left button to enter self-calibration of voltage measurement(calibration range: -0.5-0.5V, factory setting is 0.0).
"IN" indicator lights = input voltage measurement calibration starts. Then, long press(>2 seconds) the right "Mode" button, "OUT" indicator lights = output voltage measurement calibration starts.
Tap the left / right button to reduce / rise by one unit (since the voltage value of one unit is less than 0.1V, you need to 1-5 times tap the button continuously, so that the voltmeter can change by 0.1V)
3. After calibration, long press(>2 seconds) the right "Mode" button to preserve the adjusted value(no loss with outage) and back to normal voltage display.
