DC-DC adjustable converter module Key benefits - Flexible voltage from 1.5 to 35 V to suit small electronics and prototype projects - Compatible with any DC supply in the 3-40 V range - Simple, hands-on adjustment via a blue potentiometer for precise output - Allows safe operation up to 2 A continuous current; up to 3 A maximum with additional heatsink - Clear usage indication: power indicator lights when the module is powered Important notes - Input must be at least 1.5 V higher than the desired output; no boost - Output voltage is adjustable within 1.5–35 V Specifications at a glance - Input voltage: DC 3-40 V - Output voltage: DC 1.5-35 V adjustable - Output current: recommended under 2 A, maximum 3 A with heatsink How to use 1) Connect a power supply in the 3-40 V range. The power indicator illuminates when the module operates properly. 2) Adjust the blue potentiometer knob. Clockwise generally increases the output (boost), counterclockwise decreases it. Use a multimeter to monitor the output voltage and set it to the desired value. Use scenarios - Power a microcontroller or sensor project from a car or battery source (example: 12 V or 9–24 V) and drop to a stable 3.3–5 V. - Provide an adjustable test supply for electronics prototyping and bench testing from a portable DC source. - Regulate voltage for small 1.5–35 V devices in educational kits or hobby projects, using a single supply for multiple components.
