LM2596S Adjustable DC/DC Buck Converter with Built-in Voltmeter
The button to the right of the indicator switches the display of the input/output voltage. Using the button on the left, you can simply turn off the indication.
To ensure high measurement accuracy, a voltmeter calibration mode is provided. To enter the voltmeter calibration mode, select the input or output with the right button, then press and hold the right button for more than 2 seconds. Then, with the left (minus) or right (plus) button, select the value with an interval of 0.1 Volt. To exit the calibration mode, press the right button again and hold it for more than 2 seconds.
When powering the load with an operating current of more than 2A or excessive overheating of the PWM controller, you can install a radiator.
