Brand: Weewooday

Color: Multicolor

Features:

• Parameters information: input voltage is 2.5V - 40V, output voltage is 1.25V - 37V, output current is 2A (normal and stable) and 3A max, conversion efficiency 92% (highest), output ripple under 30mV, switching frequency 150KHz, operating temperature is -45 to 85 degrees Celsius
• Output current: the maximum output current can be as high as 3A, the recommended working current is about 2A, more than 2A plus heat sink
• Simple to operate: the voltmeter can be turned off, and the switch can be turned off by pressing and holding the switch for 1 to 4 seconds, once the voltmeter is turned off, simply press the switch to turn on the voltmeter, convenient to operate
• Effective design: with 150KHz internal oscillation frequency, features low power consumption and high efficiency; With terminal block, no soldering iron is also convenient to use, and retain the wire bond point (the input voltage must be higher than the voltage to be output by 1v or more)
• What you receive: package comes with 2 pieces adjustable LM2596S DC-DC buck converter to meet your use

model number: LM2596S-2

Part Number: Weewooday-903

How to use:
1. Press the button in a short time (1 second) so that IN led lighted, the voltmeter shows the value of input voltage.
2. Press the button in a short time (1 second) again so that OUT led lighted, the voltmeter shows the value of output voltage.
3. Rotate the top screw of potentiometer clockwise to boost the value of the output voltage, anti-clockwise to reduce it.
4. Long press the button between 1 and 4 seconds to turn off the voltmeter.

How to adjust accuracy of input/output voltage:
(for the person who need a highly accurate value of number)
1. Long press the button for more than 4 seconds, then release, voltmeter and IN led flash in synchronization entering into the input voltage calibration mode.
2. Press the button in a short time (1 second) to adjust the value (range from -0.5 - 0.5V), positive means to rises units, negative means to minus element. (Due to a element is less than 0.1V, so you have to continuously press 1 to 5 times to see the voltmeter change 0.1V).
3. Long press the button for more than 2 seconds and then release to enter the output voltage calibration mode.
4. After calibration, long press the button for more than 2 seconds all parameters will be saved automatically and back to the voltage display.
