All-in-One Power! Triple Output DC-DC Module, 3.3V/5V/12V from 12V Input, Perfect Power Supply for Arduino/ESP32 Projects.

Key Features & Benefits:

Three Independent Regulated Outputs: Provides simultaneous stable 3.3V, 5V, and pass-through 12V outputs, perfectly powering Arduino, ESP boards, sensors, relays, and displays with different voltage needs—no multiple adapters required.

High-Efficiency Buck Conversion: Switching buck design with >85% efficiency, low heat generation, suitable for long-term stable operation.

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

Breadboard-Friendly Design: Standard pin headers and mounting holes allow direct fixation onto a breadboard for clean and organized power distribution in your prototypes.

Clear Total Current Limit: The combined current of all three outputs should not exceed 800mA, sufficient for most prototyping needs, with clear parameters for easy planning.

Double-Sided PCB & Power LED: Quality double-sided PCB with a red power indicator for clear status monitoring.

Product Description:

Tired of connecting multiple power sources for your 3.3V and 5V devices? This compact triple-output DC-DC power module is the Swiss Army knife for your project's power needs. It efficiently converts a single 6-12V input (like a common 12V adapter) into three stable outputs, allowing you to power microcontrollers, sensors, and peripherals simultaneously. Whether for IoT development, robotics, or electronics experiments, it delivers a clean, reliable, centralized power solution.

🚨 Critical Notes Before Use! (Safety & Operating Rules)

⚠️ 【Core Warning: Input Voltage MUST Be High Enough!】

The 5V and 3.3V outputs are generated by step-down conversion. For stable operation, the input voltage must be at least 1V higher than the desired output voltage. Example: To get a stable 5V output, the input voltage must be above 6V. Using a 5V input will NOT yield a 5V output!

❌ 【Absolute Current Limit & Polarity Warning】

Total Current Cap: The sum of currents from all three outputs must NOT exceed 800mA. Overloading will cause overheating, performance drop, or permanent damage. Distribute your load wisely.
* Reverse Polarity Strictly Forbidden: Always connect according to the board's VCC (+) and GND (-) markings. Reverse connection will instantly and permanently destroy the module.

✅ 【Correct Usage Guide】

1. Select Suitable Power Source: Use a stable DC power source within 6V-12V, capable of delivering ≥1A current.
2. Connection Order: Connect the input power first (confirm red LED is on), then connect your load devices.
3. 12V Output Note: The 12V output is a direct pass-through of your input voltage (with minor drop). Its stability depends entirely on your input source quality.

🔧 【Typical Applications & Considerations】

Ideal For: Breadboard project power, multi-voltage system testing, power for small IoT gateways, educational labs.
* Not Suitable For: NOT recommended as a power source for high-power motors, bright LED strips, or other high-current devices.
* Heat Dissipation: The module will get warm when operating near the 800mA full load. Ensure proper ventilation.
