Technical Specifications

How Does It Work?

This module uses boost-conversion technology to increase the input voltage to a higher DC output voltage.

For example:

• 3.7V battery to 5V output

• 5V input to 9V output

• 5V input to 12V output

• 12V input to a higher adjustable output, within the module's operating limits

Important: The output voltage must be higher than the input voltage. This module cannot reduce voltage.

Typical Applications

• Arduino and microcontroller projects

• Battery-powered electronic devices

• DIY portable power supplies

• Sensor and electronic circuits

• Small solar-powered electronics

• LED and low-power DC projects

• Robotics and embedded electronics

• Experimental electronics and prototyping

Voltage Adjustment Instructions

1. Connect the DC power source to VIN+ and VIN−.

2. Keep the output load disconnected initially.

3. Connect a digital multimeter to VOUT+ and VOUT−.

4. Power the module.

5. Slowly adjust the onboard potentiometer while monitoring the multimeter.

6. Set the required output voltage.

7. Switch off the input supply before connecting your load.

8. Recheck the output voltage before using the connected device.

Important Installation Precautions

• Never exceed the specified input voltage.

• Always check input and output polarity.

• The output voltage must be higher than the input voltage.

• Adjust the output before connecting sensitive electronic equipment.

• Do not exceed the recommended output current.

• Provide adequate ventilation under heavier loads.

• Avoid output short circuits.

• Do not connect the module directly to mains AC.
