This document describes the Velleman VMA402, a DC-DC voltage step-up (boost) module. The VMA402 is designed to convert a microcontroller's power supply into a higher, adjustable voltage. It functions as a boost converter, meaning the output voltage will always be higher than the input voltage. This characteristic is crucial for its operation, and users are explicitly warned to ensure the output voltage is set higher than the input voltage to prevent damage to the module.

Function Description:

The VMA402 module serves as a power conversion device, specifically a boost converter. Its primary function is to take a lower DC input voltage and step it up to a higher DC output voltage. This capability is particularly useful in applications where a microcontroller or other electronic components require a higher operating voltage than what is readily available from the primary power source. The output voltage of the module is adjustable, allowing users to fine-tune it to meet the specific requirements of their application. This adjustment is performed via a multi-turn potentiometer, which provides precise control over the output voltage. The module is designed to be integrated into various electronic projects, especially those involving Arduino® or similar prototyping platforms, where different voltage levels are often needed for various sensors, actuators, or other peripheral components.

Usage Features:

The VMA402 is designed for ease of use within electronic projects. Its pin layout is straightforward, featuring clearly labeled terminals for input and output connections. "IN+" and "IN-" are designated for the positive and negative terminals of the input voltage, respectively. Similarly, "OUT+" and "OUT-" are for the positive and negative terminals of the output voltage. This clear labeling helps prevent incorrect wiring, which could damage the module or connected components. The adjustable output voltage feature, controlled by a multi-turn potentiometer, is a key aspect of its versatility. This allows users to set the exact voltage required for their specific application, making it adaptable to a wide range of electronic circuits. The module is intended for indoor use only and should be kept away from rain, moisture, splashing, and dripping liquids to ensure safe and reliable operation. Users are advised to familiarize themselves with the device's functions before use and to only use it for its intended purpose to avoid voiding the warranty. Children aged 8 and above, and persons with reduced physical, sensory, or mental capabilities, or lack of experience and knowledge, may use the device if supervised or instructed on safe use and understanding of hazards. However, children should not play with the device, and cleaning and user maintenance should not be performed by children without supervision.

Maintenance Features:

Maintenance of the VMA402 module primarily revolves around proper handling and adherence to safety guidelines to ensure its longevity and reliable performance. All modifications to the device are strictly forbidden for safety reasons, and any damage caused by user modifications will not be covered by the warranty. Users are advised to protect the device against damage by avoiding immediate power-on after exposure to temperature changes; instead, it should be allowed to reach room temperature first. Keeping the module clean and free from dust and dirt is also important for optimal operation. In case of any issues, users should refer to the Velleman® Service and Quality Warranty information provided in the manual. This warranty covers production flaws and defective materials for a period of 24 months from the original purchase date for consumer products within the EU. However, the warranty does not cover damage caused by improper handling, negligence, abuse, or use contrary to the manufacturer's instructions. This includes damage from oxidation, shocks, falls, dust, dirt, humidity, fire, water, lightning, accidents, or natural disasters. Damage resulting from commercial, professional, or collective use will reduce the warranty validity to six months. The warranty also excludes damage from inappropriate packing and shipping, or any modifications, repairs, or alterations performed by a third party without written permission from Velleman®. For repairs, the article must be delivered to a Velleman® dealer, solidly packed (preferably in original packaging), and accompanied by the original receipt of purchase and a clear description of the flaw. Before returning an article for repair, users are encouraged to reread the manual and check for obvious causes of the flaw, as returning a non-defective article may incur handling costs. Repairs outside the warranty period are subject to shipping costs. The environmental information provided emphasizes responsible disposal of the device at the end of its lifecycle. It should not be treated as unsorted municipal waste but taken to a specialized recycling company or returned to the distributor or a local recycling service, respecting local environmental rules. This commitment to environmental responsibility is a key aspect of the product's lifecycle management.
