About this item
High PrecisionThe 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 VoltageDC 3.2V to 35V (input voltage must be 1.5V higher than the output voltage, no boost).
Output VoltageDC 1.25V to 30V voltage is continuously adjustable, maximum output current is 3A.
Mini Size1.77 x 0.91 x 0.55 inches (with potentiometer). 10pcs included.
Easy to DIYConnect 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 at a high voltage, you need to contrarotate about 7-15 circles before the voltage starts ramping down, 1 circle means +/- 1V)
Dimensions: 1.77 x 0.91 x 0.55 inches.
