MB102 Breadboard Power Supply Module 3.3V/5V

The MB102 Breadboard Power Supply Module 3.3V/5V is a compact plug-in power board that clips directly onto the rails of a standard solderless breadboard, converting a single DC or USB input into clean, selectable 3.3V and 5V supplies. It is a fast, tidy way to power sensors, logic ICs and microcontroller circuits during prototyping without a bench supply.

Key features:

• Dual Output Rails: Each of the two power rails is independently jumper-selectable between 3.3V and 5V.
• Flexible Input: Accepts 6.5V to 12V through the onboard DC barrel jack, or 5V via the Micro USB connector.
• Direct Breadboard Mounting: Four power pins plug straight into the breadboard’s positive and negative rails with no extra wiring.
• Power Indicator LED: An onboard LED lights up to confirm the module is powered and active.
• Onboard Regulation: Integrated voltage regulators deliver a stable, filtered supply for sensitive analog and digital circuits.
• Compact Footprint: Sits neatly at the end of a full-size breadboard without blocking usable rows.

This module is a staple for hobbyists who want reliable, breadboard-mounted power for Arduino, sensor and IC prototyping without dedicating a bench supply or extra jumper wires to power distribution.
