This is a simple to use DC-DC step-up circuit. Use it to boost a lower voltage to an higher one. This circuit boasts a passive cooling system allowing you to power high power systems (led matrixes or motors for example).
This product is a 180 KHz fixed frequency PWM buck (step-down) DC/DC module, capable of driving a 5A load with high efficiency, low ripple and an excellent line and load regulation. The module had a voltage meter to display the input voltage and output voltage, and the voltage can be corrected through the button to improve the accuracy of the voltmeter.
