Mb102 Breadboard Power Supply Module 3.3v/5v For Arduino Solderless Bread Board

🔌 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.

✨ Key Features

• 🔌 Dual Output Voltage: 3.3V and 5V regulated outputs

• ⚡ Dual Rail Powering: Powers both breadboard power rails independently

• 🛡️ Onboard Voltage Regulators: AMS1117-3.3 and AMS1117-5.0 for stable power

• 🔄 Voltage Selection Jumpers: Switch between 3.3V or 5V per rail

• 🧩 Compatible with MB102 breadboards (standard 830-point layout)

• 🔋 Two Power Input Options: USB (5V) or DC jack (7–12V recommended)

• 💡 Power Status LEDs: Visual indicator for power-on status

• 🔒 Built-in Protection: Short-circuit and over-current protection

🧰 How to Use the MB102 Power Supply Module

🛠️ Step-by-Step Guide:

1. Insert the Module into a solderless breadboard (compatible with MB102 layout).

2. Select Output Voltage:

   • Use jumpers to choose 3.3V or 5V for each power rail (left/right).

3. 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)

4. Flip the Switch ON – Power LED lights up.

5. 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.
