DC-DC 12V to 3.3V-12V power module
DC-DC 12V to 3.3V–12V power module—adjustable step-down voltage regulator for Arduino, Raspberry Pi, and DIY electronics projects.
The DC-DC 12V to 3.3V–12V Power Module is a versatile step-down (buck) voltage regulator designed to convert a 12V DC input to a selectable 3.3V, 5V, 6V, 9V, or 12V output. This module provides stable and efficient power for a wide range of electronic circuits and devices.
Ideal for Arduino, Raspberry Pi, ESP32, sensors, LED strips, and other low-voltage electronics, it allows you to safely power components that require different voltages from a single 12V source. The module features high efficiency, overcurrent protection, and compact design, making it perfect for DIY projects, prototyping, and embedded applications.
