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 offers a highly functional design with advanced features for efficient voltage regulation. It includes a red button switch and a built-in voltmeter that has an accuracy of ±0.1V, covering a voltage range of 0-40V (please ensure the input voltage is above 4V for accurate voltmeter readings). The module allows users to toggle between measuring input and output voltage with a touch key, which also activates a light display to indicate the measured voltage.
A useful power-off memory function stores the last measured voltage, so the setting is retained when power is restored. For added convenience, a 3-second press of the touch button turns off the LED display, which can easily be reactivated with another touch. The module features screw terminals for easy wiring, eliminating the need for soldering.
With an input voltage range of 4.0-40V and a continuous adjustable output voltage range of 1.25V to 37V (ensuring the input is higher than the output by approximately 1.5V), it provides stable performance. The module supports a maximum output current of 3A, with stable operation at 2A, and runs efficiently at an internal oscillation frequency of 150KHz. Red LEDs indicate the current switching status, making it easy to monitor operation.

Frequently Asked Questions
How do I toggle between input and output voltage display?
Press the red button switch once to toggle the digital meter between showing the input voltage and the output voltage. The backlight will activate during measurement.
What is the acceptable input voltage range?
The module requires a minimum input of 4 V for accurate voltmeter readings and supports up to 40 V. Ensure your source stays within this range to avoid damage.
How do I adjust the output voltage?
Use the small potentiometer screw on the module. While observing the output voltage on the display, turn the potentiometer clockwise to increase voltage or counterclockwise to decrease it until you reach your target level.
