6 Pack LM2596 DC to DC High Efficiency Voltage Regulator 3.2-35V to 1.25-30V Buck Converter DIY Power Supply Step-Down Module
Brand: ValefodColor: BlueItem Weight: 14 GramsInput Voltage: 35 VoltsItem dimensions L x W x H: 0.9 x 1.77 x 0.55 inches【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 3.2V to 35V (input voltage must be 1.5V higher than the output voltage, no boost).【Output Voltage】DC 1.25V to 30V voltage is continuously adjustable, maximum output current is 3A.【Mini Size】45 * 23 * 14 mm (with potentiometer). 6pcs included.【straightforward 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)
