MAGT Buck Converter, Buck Step Down Regulator Module LM2596 DC/DC 4.0~40V To 1.25-37V Adjustable Reduced Voltage Regulator With LED Voltmeter

Touch the button to switch the measurement input or output voltage, and the indicator light shows which voltage is being measured, and keep the last setting, even if it is powered off and then on. The voltmeter can be turned off by pressing and holding the switch for more than 1 second and less than 4 seconds. With terminal block, no soldering iron can be used conveniently, and the wire bonding point is retained. The input voltage is 4.0~40V (the input voltage must be higher than the voltage to be output by more than 1v.). Adjustable output voltage range from 1.25V to 37V continuously adjustable (input voltage must be higher than the voltage to be output by more than 1V). The maximum output current can be as high as 3A, and the common stable operating current is 2A.
