Setup
Before connecting the module, ensure all power sources are disconnected. Observe proper polarity when making connections.
- Input Power Connection: Connect your DC power source (6V to 12V) to the DC-IN jack or the DC-IN/OUT pins. Ensure the input voltage is at least 1V higher than your desired output voltage for stable regulation.
- Output Connections:
- For 3.3V output, connect your device to the "3V3 OUT" pins and corresponding "GND" pins.
- For 5V output, connect your device to the "5V OUT" pins and corresponding "GND" pins.
- For 12V output, connect your device to the "12V OUT" pins and corresponding "GND" pins. Note that the 12V output is a direct pass-through from the input when the input is 12V.
- Mounting: The module can be mounted using the two fixing holes provided, suitable for breadboard or custom enclosure integration.

Operating Instructions
Once all connections are securely made, follow these steps to operate the module:
- Power On: Connect your DC power source to the module.
- Activate Module: Flip the blue switch (S1) on the module to the "ON" position.
- Verify Power: The red LED indicator light will illuminate, confirming that the module is receiving power and is active.
- Check Output: Use a multimeter to verify the output voltages at the respective 3.3V, 5V, and 12V output pins before connecting sensitive components.
- Power Off: To turn off the module, flip the blue switch (S1) to the "OFF" position and then disconnect the input power source.
