LM2596 ADJ DC Buck Module, High Power w/Display 2-3A

Description Including Voltage measurement display, use internal MCU for control and measurement, measurement inaccuracy within ±0.05V, range from 0 ~ 40V. (To ensure the accuracy of the volt meter, please keep to input volt over 4V) Pressing the button to switch the input or output voltage measurement, and a light show which way is being measured voltage, and save the settings, even then boot off. Voltmeter can be turned off when not needed when you can easily touch the left button With cable terminals,  can still be easy to use even no soldering iron, and retention wire connection point Input Voltage 4.0 ~ 40V (input voltage must be higher than output voltage 1.5v or more.) Adjustable output voltage range of 1.25V ~ 37V continuously adjustable (input voltage must be higher than output voltage 1.5V) The maximum output current of up to 3A, normal and stable operating current of 2A Using an internal oscillator frequency 150KHz, belongs to the second generation of switching voltage regulator, low power consumption and high efficiency. With overheating protection and short circuit protection Package do NOT include the screw anymore, also product layout update slightly but more compact (Oct. 2014) Documents please see the link here.
