Designed for quick plug-in use on MB102 breadboards, it features an ON/OFF switch, power indicator LED, and dual voltage rails for flexible prototyping with Arduino and electronics projects. ## Description 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) ## 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. ## Technical Specifications | Specification | Value | |---------------|-------| | Brand | ALAMSCN | | Product Dimensions | 1 x 1 x 1 cm; 20 g | | Item model number | AL12413 | | Manufacturer | ALAMSCN | | Color | Black | | Processor Brand | ARM | | Processor Count | 1 | | Memory Technology | DDR4 | | Are Batteries Included | No | | Item Weight | 20 g | ## Product Details - **Brand:** ALAMSCN - **Model name:** AL12413 - **Connectivity technology:** USB - **Included components:** 3 x 5 V 3.3 V Breadboard Power Supply Module, 3 x 9V Battery Snap Clip Power Cable - **CPU manufacturer:** ARM ## Images ![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) - Image 1](https://m.media-amazon.com/images/I/613gZ8lJ0qL.jpg) ## 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. ## Frequently Bought Together - 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) - ELEGOO 120pcs Multicolored Dupont Wire 40pin Male to Female, 40pin Male to Male, 40pin Female to Female Breadboard Jumper Ribbon Cables Kit Compatible with Arduino Projects - 4PCS Breadboards Kit Include 2PCS 830 Point 2PCS 400 Point Solderless Breadboards for Proto Shield Distribution Connecting Blocks --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.de/products/403958482-3-3v-5v-mb102-solderless-breadboard-power-supply-module-9v](https://www.desertcart.de/products/403958482-3-3v-5v-mb102-solderless-breadboard-power-supply-module-9v) --- *Product available on Desertcart Germany* *Store origin: DE* *Last updated: 2026-04-23*
