Complete Power Supply Kit for Breadboard Prototyping This set includes 4pcs MB102 solderless breadboard power supply modules and 4pcs 9V battery clip buckle T-type power cables with 2.1mm male DC plugs, providing a convenient and portable power solution for electronics projects, testing, and DIY prototyping. • Solderless Breadboard Design :The MB102 power supply module features a solderless breadboard design, allowing for easy and quick assembly and disassembly. This makes it ideal for prototyping and testing. • Integrated Circuits Application :Designed for computer application, this power supply module is perfect for integrated circuits, enhancing the functionality and efficiency of your electronic devices. • Compact Size :Its compact size makes it easy to handle and carry, while the 2.1x 5.5mm plug ensures easy plug-in and plug-out. Application:Power Supply Module Widely Applied for Single-Chip Microcomputer, Electronic Building Blocks, Smart Car, Robot and Other Power Supply Expansion,Simple and Practical Specifications • Locking ON / OFF Switch • LED Power Indicator • Input Voltage: 6.5 V to 12 V (DC) • Output Voltage: 3.3 V / 5 V DC • Maximum Output Current: 700 mA • Power Rails 0 V, 3.3 V, 5 V on Breadboard • Two Groups of Header Pins • 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 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.
