Specification: USB interface: USB type A female Quantitty: 10pcs Package weight: Approx. 31g/1.1oz Package List: 10 * USB Breakout Board  Specifications: Input Voltage: 3V-35V Output Voltage: 5V-45V Input Current: 5A(Peak) Voltage Display Range: 5V-30V(if input voltage is lower than 4.5V, it will not display) Voltage Display Error: +/-0.1V Size: 72*48*16mm / 2.83*1.89*0.63" Note: 1, This is a boost module so output voltage should be higher than input voltage. 2, Peak output current is less than 5A. 3, This kit requires professional knowledge and ability, please make sure you know how to use it. Instruction: 1. Connect the module to power supply (4.5-40V), the input indicator light is on, and module is working normally. 2. Adjust the blue potentiometer knob (generally turn clockwise to step up and turn counterclockwise to step down) and check the output voltage with a multimeter until it meets requirement. 3.If the output voltage of the module can not be adjusted, which means it is always equal to the input voltage, please turn the potentiometer counter-clockwise for several circles then the voltage can be adjusted normally. Package Includes: 1 x Boost Module
