MT3608 DC-DC Boost Module 2A Boost Power Supply Board Step Up Converter Booster MT3608 Boost Power Supply Board Input Adjustable and ! Tip: Reverse the potentiometer 20 times before taking the goods to test! Pressure regulation Facing the chest, the potentiometer turns counterclockwise to boost! Some customers report that the output voltage of the module cannot be adjusted and is always equal to the input voltage. When you encounter this kind of problem, please turn the potentiometer counterclockwise more than 10 turns, and then use the module to adjust the voltage normally. Method of use The module of the IN and - after 2~24v, IN adjusting the potentiometer can adjust output voltage, output voltage is greater than the input voltage Matters needing attention 1). The input voltage should not exceed the maximum input voltage 2). The peak current output current is no more than TV university Specifications: Electrical characteristics 1). The maximum output current: 2 a 2). The input voltage: 2 v ~ 24 v 3). The maximum output voltage: 28 v 4). Efficiency: 93% Mechanical properties 1). product size: 36 mm X 17 mm X 14 mm Package Included: 1 x MT3608 DC-DC Step Up Power Apply Module Booster Power Module MAX output 28V
