Vszerda MB102 Breadboard Power Supply Module 3.3V 5V

SKU CH-GEG7-YN4B7

Provides selectable 3.3V or 5V power to a solderless breadboard

  • Dual 3.3 V and 5 V rails power mixed-voltage circuits
  • MB102 form factor plugs straight into solderless breadboards
  • 3 V output suits low-voltage microcontrollers and sensors
  • 5 V output drives standard logic and peripherals

MB102 Breadboard Power Module

The Vszerda MB102 is a compact power supply module designed to plug directly into a solderless breadboard. It provides selectable 3.3 V and 5 V outputs through dual independent rails, allowing developers to power different sections of a circuit simultaneously. An on-board switch controls each rail, and the unit accepts input from a DC barrel jack or USB connection for flexible bench use.

Makers prototyping low-voltage circuits

This module suits hobbyists and engineers building sensor networks, microcontroller projects or IoT edge devices that need clean dual-voltage rails on a breadboard. It is not intended for applications requiring higher voltages, adjustable output levels or power delivery beyond the fixed 3.3 V and 5 V rails. Buyers needing variable bench supplies or mains-powered units should look elsewhere.

Questions about this item

Which voltage output should I select on the MB102 module for my project?

The module provides two selectable outputs, 3.3 V and 5 V. Choose 3.3 V for low-voltage microcontrollers or sensors, and 5 V for standard logic circuits.

What does the 3.3 V rail deliver when the board is plugged into a solderless breadboard?

It supplies a regulated 3.3 V directly to the breadboard power rails, ready for components that require that voltage level.
