About this item

The WeAct Studio Buck Step-Down Power Module is a compact and efficient DC-DC converter designed to step down input voltages up to 36V to a stable 3.3V output. With a maximum output current of 0.6A, this module is ideal for powering 3.3V logic circuits, sensors, microcontrollers (like STM32, ESP32, etc.), and other low-power embedded devices from higher-voltage sources such as 12V or 24V systems. Built with high-efficiency switching regulator technology, this buck converter ensures minimal heat generation and low power loss, even under continuous operation. The module features onboard filtering capacitors and a fixed output design, offering clean, noise-reduced 3.3V power that is suitable for sensitive electronics. Its small form factor and 2.54mm pin spacing make it breadboard-friendly and easy to integrate into prototypes or permanent installations. The wide input range and stable output also make it a perfect solution for DIY projects, industrial applications, and automotive systems where regulated 3.3V power is required. The module includes reverse polarity protection and thermal shutdown features for safe and reliable operation in demanding environments.
