## Overview

The ALAMSCN MB102 Power Supply Module delivers regulated 3.3V and 5V outputs up to 700mA, designed for MB102 breadboards. It features a convenient ON/OFF switch, green LED power indicator, and supports 6.5-12V input via a 2.1x5.5mm barrel jack or 9V battery clip. This solderless, plug-in module streamlines powering Arduino and other microcontroller projects, making prototyping faster and safer.

## Description

desertcart.com: ALAMSCN 3.3V 5V MB102 Solderless Breadboard Power Supply Module with 9V Battery Clip Power Cable 2.1x 5.5mm Male DC Jack Plug for Arduino (Pack of 3) : Electronics

## Features

- There is a green LED to indicate the presence of power, and an ON / OFF latching switch to control the power to the board.
- The input voltage through the barrel socket must be between 6.5 V and 12 V. Hence, if you wish to use it to its maximum capability you will need to remain in that range. This is a non-adjustable fixed power supply model, which is good enough for most applications.
- Maximum output current to be 700 mA. However, it is probably better to use much lower voltages and current to be on the safe side in case you make a mistake on your breadboard circuit.
- With 9V battery snap power cable T-type 5.5x2.1mm connector.
- How to use: This is a plug-in power supply and the headers below the board simply plug-in to the breadboard. Once plugged in, the voltage rails to both sides on the breadboard then provide power. You then use the yellow jumpers to select the voltage levels required. This is a dual output 3.3 V, 5 V regulated board and you can have either voltage on either rail on the breadboard, which is very useful.

## Questions & Answers

**Q: Is the input ok for 12v? The pictures say 6-9v, the description says 6-12v?**
A: I recently ordered some of these so I just checked. The board itself says "DC in, 7-12 volts". Please keep in mind that some fully charged 12 volt batteries can produce a voltage of 13+ volts. I've not tested so I cannot say for sure. If you are regulated @ 12 volts you should be fine.

**Q: Is the voltage regulated by linear or switching regulator?**
A: Linear

**Q: Can these be used to provide a positive rail and negative rail?**
A: No. It's either 5 or 3.3v

**Q: Are these good for testing guitar pedal circuits?**
A: These are good for any low current application where the requirements are 3.3V - 5V input. These allow a 9V battery to be used to supply the proper input power to your circuit. Hopefully this helps.
