SPECIFICATIONS

All-in-One Power Hub! Triple Output DC-DC Buck Module, Powers Your Arduino, Sensors, Display & Amp Simultaneously.

Key Features & Benefits

Three Independent Regulated Outputs: Simultaneously delivers stable 3.3V (±0.05V), 5V (±0.05V), and pass-through 12V outputs. Power your Arduino, ESP32, sensors, OLED, relays, and even audio amplifiers all at once.

High Efficiency, Low Heat: Switching buck design with >85% conversion efficiency, runs cool for reliable long-term operation.

Wide Input Voltage Range: Accepts 6-12V DC input, compatible with common 12V adapters, 3S Li-ion packs, car batteries, or solar panels.

Breadboard-Friendly Design: Standard pin headers and mounting holes allow direct fixation on your breadboard for a clean and organized prototyping workspace.

Clear Total Power Limit: A combined maximum current of 800mA for all three outputs meets the needs of most multi-module projects. Clear specs for safe design.

Quality Build & Indicator: Double-sided PCB with clean layout. Red power LED for clear status indication.

Product Description
Tired of juggling multiple power adapters for different components? This compact triple-output DC-DC power module is the perfect central power station for your prototypes. From a single 6-12V input, it provides both the 3.3V/5V logic voltages needed for microcontrollers and the 12V power for peripherals like relays or amplifiers. Whether for IoT devices, robotics, or DIY audio projects, it delivers clean, stable power so you can focus on creating, not on cable clutter.

🚨 Important Notes / How to Use (Proactively Prevent Negative Reviews)

Sufficient Input Voltage REQUIRED: Input voltage MUST be at least 1V higher than your highest required output. For example, for a stable 5V output, input MUST be >6V. A 5V input will NOT work.

STRICTLY Observe Total Current Limit: The sum of currents from ALL THREE outputs MUST NOT exceed 800mA. Overloading will cause overheating, shutdown, or permanent damage. Distribute your load wisely.

Reverse Polarity PROHIBITED! Strictly follow the VCC (+) and GND (-) markings on the board. Reverse connection will instantly destroy the module!

Note on 12V Output: The 12V output is a direct pass-through of your input voltage (with minor drop). Its stability depends entirely on your input source quality.

Recommended Connection Order: Connect input power first (confirm red LED is ON), then connect your load devices.
