Description
Mb102 Breadboard Power Supply Module 3.3v/5v For Arduino Solderless Bread Board in Lahore Pakistan
🔌 MB102 Breadboard Power Supply Module – 3.3V / 5V for Arduino & Solderless Breadboard
✅ Product Overview
The MB102 Breadboard Power Supply Module is a compact and essential tool for electronics prototyping. Designed to plug directly into a standard solderless breadboard, it provides a clean and regulated 3.3V and 5V output, selectable via onboard jumpers.
Ideal for Arduino, Raspberry Pi, ESP8266, and other microcontroller-based projects, this power module is powered by either a DC barrel jack (7–12V) or USB input, making it highly versatile for bench or portable use.

🧰 How to Use the MB102 Power Supply Module
🛠️ Step-by-Step Guide:
-
Insert the Module into a solderless breadboard (compatible with MB102 layout).
-
Select Output Voltage:
-
Use jumpers to choose 3.3V or 5V for each power rail (left/right).
-
-
Connect Power Source:
-
Option 1: Use a DC adapter (center-positive, 7–12V recommended)
-
Option 2: Plug in via USB port (5V USB cable or power bank)
-
-
Flip the Switch ON – Power LED lights up.
-
Start powering your Arduino, ESP8266, sensors, or other components directly from the breadboard rails.
⚠️ Note: Do not use USB and DC input at the same time. Choose one power source only.
