LM2596 DC-DC Adjustable Step-down Module with Digital Display Voltmeter (Red Button Switch)
The LM2596 DC-DC Adjustable Step-down Module with Digital Display Voltmeter features a red button switch and a built-in voltmeter with an error margin of ±0.1V, covering a voltage range of 0-40V (note: ensure input voltage is 4V and above for voltmeter accuracy). It allows for toggling between measuring input and output voltage via a touch key, with a corresponding light display indicating the measured voltage. The module includes a power-off memory function, retaining the last measured voltage upon power restoration. Additionally, a 3-second press of the touch button disables the LED display, which can be reactivated by touching the button again. With convenient screw terminals for wiring, no soldering is required. The input voltage range is 4.0-40V, ensuring the output voltage exceeds 1.5V. It offers a continuously adjustable output voltage range of 1.25V-37V, provided the input voltage is higher than the output by about 1.5V. With a maximum output current of 3A and stable operation at 2A, it operates at an internal oscillation frequency of 150KHz, delivering low power consumption and high efficiency. Red LEDs indicate current switching status.
