TECNOIOT LM2596 DC-DC Adjustable Step-Down Power Module + LED Voltmeter DC/DC

• LM2596: LM2596 DC 4.0-40 to 1.3-37V Adjustable Down Power Module + LED Voltmeter DC/DC
• Easy to use: Input voltage range: 4-40 V (40 V to limit the highest voltage). Output voltage range: 1.25 V - 37 V (decompression mode, input output should be greater than 2 V).
• Compact design: with the voltage display function, the displayed accuracy is ± 0.05 V, the range is between 0 and 40 V. (Note: To get a more accurate voltage display, please make sure the input voltage is higher than 4V).
• 【High Performance】 Button for switching the input or output voltage measurement and LED indicates the current measurement of input or output voltage; the Nixie tube can be switched off with another button. Entries in these states can be saved and will not be lost even if the power supply is interrupted.
