6Pcs LM2596 Power Converter Step Down Module DC to DC Buck Converter 3.2V-35V to DC1.25V-30V Voltage Regulator Power Supply Module LM2596S

6Pcs LM2596 Power Converter Step Down Module DC to DC Buck Converter 3.2V-35V to DC1.25V-30V Voltage Regulator Power Supply Module LM2596S

• DC-DC step-down power supply module input: DC3.2v-35v (input voltage must be 1.5 V higher than the output voltage, no boost)
• DC-DC step-down power supply module output: DC1.25v-30v voltage is continuously adjustable, maximum output current is 3 A
• LM2596 is a buck module, the input voltage must be higher than the output voltage and cannot boost.
• Note: Before using it for the first time, when the module is de-energized and not connected to a load, turn the copper-headed adjustment cap of the blue potentiometer (aim it at your chest) counterclockwise to the end (more than 30 turns). Hear There is a "click" sound, and finally power on, use a multimeter to monitor the module output voltage, and turn the potentiometer clockwise to reach the ideal voltage
