## Description

Full description not available

## Features

- High Precision :The buck converter consists of thickened circuit boards, high-Q inductance with output LED indicator, and superior solid-state capacitors that can effectively filter out high frequency noise. Suitable for various electronic projects.
- Input Voltage : DC 4V to 35V (input voltage must be 1.5V higher than the output voltage, no boost).
- Output Voltage : DC 1.25V to 30V voltage is continuously adjustable, maximum output current is 3A. Working Temperature: -45 ~ +85 deg C.This board comes with inbuilt current limit funciton and output short circuit protection.
- Easy to DIY: Connect to power source, using a mini screwdriver to increase or decrease output voltage by adjusting the screw on the blue potentiometer and monitor voltage with multimeter to get the needed voltage, clockwise to step up voltage and counterclockwise to step down voltage. (Factory default stays a high voltage, you need to "rotate about 7-15 circles" before the voltage starts ramping down, 1 circle means +/- 1V)
- Applications: Widely used for DIY Mobile power, Contstant power supply, Power buggies, Communications equipment power supply, Motor controllers, Drills, Led ,Robotics projects, Transformers, etc.
