Product Introduction
This USB to Micro USB Step-Down Converter Cable reduces the standard 5V USB voltage down to 3.3V (or 3V), making it perfect for powering Arduino modules, ESP8266 boards, low-voltage sensors, and other DIY electronic components that require a lower voltage input.
It's a convenient solution for hobbyists, technicians, and makers who work with sensitive microcontrollers or 3.3V systems.
