💡 What is a buck converter module used for in hobby electronics?

Buck converters are handy for powering low voltage electronics from a higher voltage supply. They’re a handy part of many workbenches for quick, adjustable voltage supplies.

• Efficient voltage reduction from higher sources to 3.3V, 5V, or other low rails
• Helpful for microcontrollers, motion sensors, and LED drivers in DIY kits
• Can run from AC or DC inputs within its rated range for flexible setups
• Works well in prototyping and small-scale hobby projects
