The HW-601 3A DC adjustable step-down voltage module is a compact and precise digital power supply board designed for controlling voltage and current in a wide range of electronic, industrial, and educational projects. Built around the MP2307 high-frequency switching regulator, this module converts a DC input voltage of 5V to 23V into a continuously adjustable output voltage from 0V to 16.5V, delivering a stable output current of up to 3A (2A recommended for continuous operation). The advanced switching architecture achieves a conversion efficiency of up to 95%, minimizing energy loss and heat generation during operation.

The module features a bright digital LCD display with a wide viewing angle and backlight, allowing users to simultaneously monitor output voltage and current in real time. On-board tactile push buttons enable quick and precise voltage adjustment, and the module automatically saves the last set voltage even after power is removed. The display resolution is 0.01V with an ammeter accuracy of 1%, and the module includes a voltage calibration function that allows users to fine-tune the displayed value to match a multimeter reading, achieving deviation as low as 0.04V.

With compact dimensions of 62mm × 44mm × 18mm and a weight of approximately 45 grams, the MP2307 step-down converter is suitable for integration into laboratory bench power supplies, test circuits, control systems, and robotics projects. The load regulation and voltage regulation are both rated at ≤0.8%, ensuring stable and reliable performance even under varying load conditions. This digital step-down voltage regulator module is an ideal choice for powering sensitive equipment and precision circuits.
