LM2596 5V 9V 12V 24V DC to DC DC-DC Step Down Voltage Regulator Module with Display for Arduino

Specification:

 

1. With the voltmeter shows voltage meter error ± 0.1V, the range 0-40V. (Note: To ensure the accuracy of the voltmeter, please ensure that the input voltage of 4V and above)

2. Touch the key to switch measuring input or output voltage, and has a light show which is being measured voltages

3. Power off memory function, show that road after power voltage values measured for the last time

4. Press the touch button for 3 seconds to turn off LED display, touch the button again to turn on the LED display

5. The band terminals, no iron can also be easy to use, and retention wire connection point

6. Input voltage 4.0-40V (input voltage to the output voltage must be higher than 1.5v.)

7. The adjustable output voltage range of 1.25V-37V continuously adjustable (input voltage must be higher than the output voltage to a high of about 1.5V)

8. The maximum output current up to 3A, normal and stable operating current of 2A

9. the internal oscillation frequency 150KHz, belonging to the second generation of switching voltage regulator, low power consumption, high efficiency

10. The current switching LEDs are red



PINOUT :

VIN+  =  Voltage Input (Positive)

VIN-   = Voltage Input (Negative) / Ground

VOUT + = Voltage Output (Positive)

VOUT - = Voltage Output (Ground)



How to adjust the output voltage?

- Adjust the blue potentiometer to step down or up voltage.
