DollaTek 10Pcs DC to DC High Efficiency Voltage Regulator 3.0-40V to 1.5-35V Buck Converter DIY Power Supply Step Down Module

• 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.
• DC 3V to 40V (input voltage must be 1.5V higher than the output voltage, no boost).
• DC 1.5V to 35V voltage is continuously adjustable, maximum output current is 3A.
• 45 * 23 * 14 mm (with potentiometer). 8pcs included.
• 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.
