MT3608 DC Boost Converter 2A Adjustable Module Voltage Regulator Board Input 2 Volt 24 to 5 28 Output

Mini DC-DC step up voltage regulator with DC 2-24V input and 5V-28V output,just connected with USB power adapter then you can get 9V 12V 18V 24V voltge. Equipped with voltage booster chip with high conversion efficiency up to 93%. Widely used for storage battery, power transformers, DIY adjustable regulated power supply, industrial equipment, 5V, 9V, 12V, 28V output, etc. Includes under-voltage lockout, current limiting, and thermal overload protection to prevent damage in the event of an output overload. Note: Before the first use, the module is not powered and not connected to the load, the blue potentiometer copper head a word mouth adjustment cap, aligned with the direction of the chest, counterclockwise rotation of the potentiometer to the end of the "ta" sound, and then clockwise rotation of the potentiometer more than 30 turns, and finally connected to the power supply, using a multimeter to monitor the module's output voltage to achieve the desired voltage
