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, Arduino 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 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.
