MCU Micro USB Breadboard 5V Power Supply Module

MCU Micro USB Breadboard 5V Power Supply Module 

The Micro USB Breadboard Power Supply Module is a compact voltage regulator board designed to provide a stable 5V or 3.3V output directly to a standard MB102 breadboard.
It is powered through a Micro USB connector or an external DC input header.
The module includes an onboard voltage regulator and jumpers to switch between 5V and 3.3V output rails, making it ideal for powering microcontroller-based prototypes such as Arduino, ESP8266, ESP32, STM32, and sensor circuits.
