Regulator module 9v to 5v

πŸ”‹ 9V to 5V Regulator Module – DC-DC Buck Converter

This compact Regulator Module efficiently steps down 9V (or higher) input voltage to a stable 5V DC output, making it perfect for powering Arduino boards, ESP8266/ESP32, sensors, and USB-powered devices. Based on a DC-DC buck converter design, it is energy-efficient and provides consistent output voltage even under varying input.
