6 Pcs Lm2596 Dc Dc Buck Converter Step Up Down Converter Module High Efficiency Voltage Regulator 3.0 40V To 1.5 35V Adjustable Boost Converter Dc Power Supply Module Multicolour

Highlights

• input voltage is DC 3 V to 40 V (input voltage must be 1.5 V higher than the output voltage, no boost) , and output voltage is DC 1.5 V to 35 V voltage, maximum output current is 3 A.
• Made of 36u thickened circuit boards, high-Q inductance with output LED indicator, and superior solid-state capacitors, these DC to DC modules can work with high effect.
• Connect to power source, adjust the swirl button 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 18V, you need to contrarotate about 7-8 circles before the voltage starts ramping down, 1 circle means +/- 1V)
