Voltage converters
Voltage converters for converting direct or alternating current to the desired (DC) voltage for your electronics project. Think of lowering (step-down), raising (step-up), or stabilizing a voltage for, for example, Arduino, ESP8266, or sensors. Buck converters are more efficient at this than 'ordinary' voltage converters.
In this category, you will find both AC-DC modules (mains voltage to low DC voltage) and DC-DC converters in various designs, often adjustable and easy to use.
