DFROBOT DFR0205 Power Module

This Power Module is a small size 5A 350KHz 25V Buck DC to DC Converter. It can convert any DC voltage between 3.6V-25V to a selectable voltage from 3.3V to 25V. You can choose 5V direct output voltage with the convenient on-board switch or adjust the output voltage by the blue and white resistor. Three different output interfaces for convenient and fast prototyping of projects with multiple voltage requirements. The Ovout (Original Voltage output) interface can output the power supply voltage of input so that can be used to power other parts as well. This interface proves very helpful when using a power supply that fits the requirements for one component, and then use the power module to adapt the power for the other components. The ON/OFF button on the board can be pulled high to turn the converter module on and low to turn it off.
