6 Pack LM2596 DC to DC Buck Converter 3.0-40V to 1.5-35V Power Supply Step Down Module 6 Pack

Input: DC 3 V to 40 V (input voltage must be 1.5 V higher than the output voltage, no boost)
Output: DC 1.5 V to 35 V voltage is continuously adjustable, maximum output current is 3 A
Features: use SANYO solid-state capacitors, 36 u thickening circuit boards, high-Q inductance with LED indicator output
Quantity: 6 pieces
Size: 43x21x14mm
Steps: connect to power source, adjust the swirl button on the blue potentiometer and monitor voltage with multimeter to get the needed voltage (The factory have tested these at max voltage so they are very high by default, takes about 15-20 turns CCW before the voltage starts ramping down)
Notes:
The input and output interface can not be reversed.
Keep it under 2.5 A and use the heat sink when working for long hours.
