DC-DC Adjustable Buck Boost Power Supply Module

Take full control of your voltage needs with this compact DC-DC Adjustable Buck Boost Power Module. Whether you're prototyping electronics, powering custom circuits, or building DIY projects, this versatile converter delivers stable, adjustable output across a wide voltage range — from 3.3V all the way up to 24V. With built-in USB connectivity and a clear digital display (DP), you can monitor and fine-tune your power output quickly and precisely.

Key Features

Wide Voltage Range: Adjustable output supports 3.3V, 5V, 9V, 12V, 24V and everything in between — both buck (step-down) and boost (step-up) conversion in a single module.
Digital Display (DP): Onboard numeric display lets you read output voltage at a glance for accurate adjustments every time.
USB Port: Integrated USB output makes it easy to charge or power USB-compatible devices directly from your circuit.
Two Color Options: Available in Red or Green to match your build aesthetic or help organize multi-module setups.
Stable Output: Engineered for consistent, low-ripple voltage delivery — ideal for sensitive electronics and precision DIY work.
Compact & Versatile: Small form factor fits neatly into breadboards, enclosures, and project boxes without taking up valuable space.
Easy to Use: Simple rotary adjustment and plug-and-play USB interface mean no complex setup required.

Frequently Asked Questions

Q: What does a DC-DC buck boost power module do?

A: A DC-DC buck boost power module converts an input voltage to a different, adjustable output voltage. "Buck" means it steps voltage down (e.g., 12V in → 5V out), while "boost" steps it up (e.g., 3.3V in → 12V out). This module handles both, giving you a single flexible tool for a wide range of electronics projects.

Q: What output voltages does this adjustable power module support?

A: The module supports a wide adjustable output range covering common values including 3.3V, 5V, 9V, 12V, and 24V. You can fine-tune the output using the onboard rotary control while monitoring the exact voltage on the built-in digital display.

Q: Is the USB port on this DC-DC module for input or output?

A: The USB port functions as an output, allowing you to directly power or charge USB-compatible devices from your regulated power source — a handy feature for projects that need to supply USB-standard 5V alongside other voltage rails.

Q: What is the difference between the Red and Green color versions?

A: Both color variants (Red and Green) are functionally identical — the color simply refers to the PCB or indicator LED color. Many makers choose different colors to visually distinguish between multiple modules used in the same project or workspace.
