Featuring a wide input range (4V-35V), precise voltage tuning (1.25V-30V), and built-in safety protections, it’s engineered for reliable, noise-free power supply in diverse electronic and DIY applications. ## Description Full description not available ## Features - High Precision :The buck converter consists of thickened circuit boards, high-Q inductance with output LED indicator, and superior solid-state capacitors that can effectively filter out high frequency noise. Suitable for various electronic projects. - Input Voltage : DC 4V to 35V (input voltage must be 1.5V higher than the output voltage, no boost). - Output Voltage : DC 1.25V to 30V voltage is continuously adjustable, maximum output current is 3A. Working Temperature: -45 ~ +85 deg C.This board comes with inbuilt current limit funciton and output short circuit protection. - Easy to DIY: Connect to power source, using a mini screwdriver to increase or decrease output voltage by adjusting the screw on the blue potentiometer and monitor voltage with multimeter to get the needed voltage, clockwise to step up voltage and counterclockwise to step down voltage. (Factory default stays a high voltage, you need to "rotate about 7-15 circles" before the voltage starts ramping down, 1 circle means +/- 1V) - Applications: Widely used for DIY Mobile power, Contstant power supply, Power buggies, Communications equipment power supply, Motor controllers, Drills, Led ,Robotics projects, Transformers, etc. ## Technical Specifications | Specification | Value | |---------------|-------| | Brand | R&D | | Manufacturer | R&D | | Colour | Multicolor | | Number of Memory Sticks | 1 | | Item Weight | 60 g | | Package Dimensions | 15.24 x 10.67 x 4.83 cm; 60 g | | Item part number | Lm2596 | | Power Source | Corded Electric | | Included Components | 1 | ## Images ![Lm2596 Dc -dc Buck Converter Step Down Module Adjustable Voltage Power Supply Module/Board/kit, A 24v to 18V/12V/9V/5V, 12V to 9V/5V 3A/Ampere - Image 1](https://m.media-amazon.com/images/I/61QxDubAVGL.jpg) ![Lm2596 Dc -dc Buck Converter Step Down Module Adjustable Voltage Power Supply Module/Board/kit, A 24v to 18V/12V/9V/5V, 12V to 9V/5V 3A/Ampere - Image 2](https://m.media-amazon.com/images/I/61td19n6YzL.jpg) ![Lm2596 Dc -dc Buck Converter Step Down Module Adjustable Voltage Power Supply Module/Board/kit, A 24v to 18V/12V/9V/5V, 12V to 9V/5V 3A/Ampere - Image 3](https://m.media-amazon.com/images/I/61ywFlTD-DL.jpg) ![Lm2596 Dc -dc Buck Converter Step Down Module Adjustable Voltage Power Supply Module/Board/kit, A 24v to 18V/12V/9V/5V, 12V to 9V/5V 3A/Ampere - Image 4](https://m.media-amazon.com/images/I/61UcRd0MQ8L.jpg) ![Lm2596 Dc -dc Buck Converter Step Down Module Adjustable Voltage Power Supply Module/Board/kit, A 24v to 18V/12V/9V/5V, 12V to 9V/5V 3A/Ampere - Image 5](https://m.media-amazon.com/images/I/61lYhgZ-nXL.jpg) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.be/products/590210816-lm2596-dc-dc-buck-converter-step-down-module-adjustable-voltage](https://www.desertcart.be/products/590210816-lm2596-dc-dc-buck-converter-step-down-module-adjustable-voltage) --- *Product available on Desertcart Belgium* *Store origin: BE* *Last updated: 2026-04-29*
