It has a switch and a led indicator, that's also handy while experimenting with some breadboard project. One weak spot: there is no short-circuit protection, not even a fuse, and if its shorted, the regulators will overload and blow out within seconds. I'm thinking on adding at least a fuse instead of the voltage selector jumper, because otherwise this circuit is just perfect. ## Technical Specifications | Specification | Value | |---------------|-------| | Brand | UIOTEC | | Graphics card description | Dedicated | | Included components | 1 PCS MB102 Breadboard Power Supply Module 3.3V 5V For Arduino Solderless | | Model name | MB102 | | Special features | Arduino Solderless Breadboard Compatibility | | Specific uses for product | Electronic Prototyping | ## Product Details - **Brand:** UIOTEC - **CPU model number:** MB102 - **Connectivity technology:** USB - **Graphics card description:** Dedicated - **Included components:** 1 PCS MB102 Breadboard Power Supply Module 3.3V 5V For Arduino Solderless - **Model name:** MB102 - **Special features:** Arduino Solderless Breadboard Compatibility - **Specific uses for product:** Electronic Prototyping ## Images ![MB102 Breadboard Power Supply Module 3.3V/5V for Arduino Board Solderless Breadboard - Image 1](https://m.media-amazon.com/images/I/51vZXVSgKYL.jpg) ![MB102 Breadboard Power Supply Module 3.3V/5V for Arduino Board Solderless Breadboard - Image 2](https://m.media-amazon.com/images/I/61-XyITyhIL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ good item *by H***I on 18 September 2022* good item ### ⭐⭐⭐⭐ Worth the price *by G***N on 25 July 2019* The arrangement is practical, its 5V and 3.3V outputs are quite stable, the noise is negligible.
