Product description: 3.3V adjustable step-down converter - 25V 5A - DFRobot DFR0205.
Inverter module for converting input voltagefrom 3.6 V to 25 V, to output voltagefrom 3.3 V to 25 V. The current capacity for 5 V is 5 A.The input voltage must be higher than the output voltage.
Step-down converter - adjustable.
The module has three different output interfaces, such as goldpin, ARK connectors and JST 2-pin raster 2.54 mm. On the python there is a power switch and a potentiometer to set the output voltage, as well as a switch for 5 V or set by the potentiometer.
Module outputs
The board is equipped with three different output interfaces: goldpin, ARK and JST connectors.
