The Whadda WPM402 is an ideal solution for hobbyists and electronics engineers needing to boost a lower input voltage to a higher, adjustable output for microcontroller projects. While it provides excellent flexibility for powering diverse components, users must ensure their power source does not exceed the 3A peak input current limit to prevent damage to the module.

The module accepts an input voltage range of 3.5V to 35V DC.
No, this is a boost (step-up) converter only; it cannot lower the input voltage.
The module supports a continuous input current of 2A.
Yes, it is highly recommended to use a multimeter to set the desired output voltage before connecting your load.
The dimensions are 43 x 30 x 12 mm, making it very compact for DIY projects.
Ensure the input voltage is within the specified 3.5-35V range and check that the potentiometer is not at its mechanical limit.
Verify that your load is not drawing more than the 2A continuous current limit and consider adding a small heatsink.
Double-check input polarity and verify that the input voltage source is providing sufficient power.
To set up the module, ensure your input polarity is correct as reversing it may damage the circuitry. When adjusting the output, rotate the potentiometer slowly while monitoring with a multimeter. Avoid touching the module while it is under high load as components may become warm. Ensure the module is mounted in a well-ventilated area to allow for natural heat dissipation. Periodically check that all connections are secure, as loose wires can cause voltage spikes or intermittent power loss.
