"Introducing the Dual Display DC-DC Voltage Regulator Module, a powerful and versatile buck converter that allows you to step down voltages from 5V to 23V to a range of 0V to 16.5V. Equipped with an STC LCD screen, this module displays the output voltage and current for easy reading and convenience. It also features reverse protection for added safety.

This voltage regulator module stands out with its on-board tactile push button, which offers precise regulation of the output voltage, surpassing the traditional potentiometer. Additionally, it comes with an outer shell design, making it a portable digital voltmeter once assembled, offering both protection and convenience.
