upgrade version of the Adjustable Mini DC-DC Module. It integrated a volage meter with the DC-DC module – LM2596S, with this function, you can monitor your project much more easier. The voltage meter can measure the input voltage or output voltage, which is adjustable by the protentiometer, with a precision of ±0.1V.Note that the voltage meter would not work if the input voltage below 4V. Press the button to switch voltage to measure, between the input voltage and output voltage. There are also 2 LEDs (IN and OUT) to indicate which voltage is measuring by the voltage meter. You can also close the voltage meter by long pressing the button (1S 4S) the button makes the module enter the calibration model, after releasing the button, the related LED would light up to indicate which voltage is now calibrating, and the numeric display blinks the correction value.(Default: 0.0V) 2. Short press the botton to change the correction value(-0.5V ~ 0.5V), for example, if your power supply is 5V, but the result of voltage meter is 4.8, you need to set the correction value to +0.2V. 3. Long press (press time ? 2S), to store the input voltage correction value, the module will enter the output voltage correction value calibration model automatically. 4. Calibrate the output voltage in the same way above; The correction value will be stored in nonvolatile memory.Power Source: DCRoHS CompliantMaterial: Fiber GlassWeight: 0.22: 1 pcs of Adjustable Integrated DC-DC Module LM2596S, STORAGE BOXbrand: robokitshopModel Number: Adjustable Integrated DC-DC Module LM2596SType: Power SupplyMinimum Age: 8ROHS Complaint: YesOther Features: N/AWidth: 10Height: 1Other Dimensions: 66mm x 35mm x 14mmBattery Type: DCNo Of Batteries: 1Battery Size: 0Power Consumption: 4-40V /3AOther Power Features: Input Voltage: 4V~40V (1.5V higher than the output at least), Measurement Accuracy: ±0.1V, Adjustable Output Voltage: 1.5V~35V., Output Current: 3A
