Description
Adjustable DC-DC Buck-Boost Converter Module 1.25V–26V Output
The Boost + Buck DC-DC Power Supply Module is a versatile voltage regulator designed to both step-up (boost) and step-down (buck) input voltage to a stable, adjustable output. Built using reliable IC combinations like LM2596, XL6009, and LM2577, this module ensures efficient power conversion for a wide range of electronics applications.
With a broad input voltage range and adjustable output, it is ideal for powering Arduino, ESP32, Raspberry Pi, LED drivers, motors, and battery-powered systems. The onboard multi-turn potentiometer allows precise voltage adjustment, while high-efficiency switching ensures minimal power loss.
This module is perfect for DIY electronics, robotics, IoT projects, and embedded systems, where flexible voltage regulation is required.
