## Description

DC-DC step-down converter with LCD display, ideal for powering electronic projects and charging batteries with stabilized voltage and current. Offers fine adjustment of the output 0-16.5V from 5-23V, quick two-button control, real-time measurement of voltage and current on the LCD, high efficiency up to 95% and maximum current 3A with adequate cooling.
Automatic step-down DC-DC voltage source module, adjustable voltage, with an LCD display showing the voltage and the consumed current.
The output voltage is adjusted using the two buttons located on the board.
The module is suitable for battery charging (as long as the battery specifications are respected) due to the stabilized voltage and current.
Note: the display is mounted slightly tilted because of the short pins and the components underneath it.
