This is a pack of five power supply modules that work with MB102 breadboards and prototype boards. Each module gives you switchable output between 3.3V and 5V, so you can power different components depending on what you're building. The input takes either a 6.5 to 9V DC source or USB power, making it flexible for different setups. Maximum output current is 700mA per module, which handles most hobby projects without issues.
The board features two independent voltage control switches, so you can set each output to 0V, 3.3V, or 5V independently. This means you get dual outputs per module, giving you options when you need multiple power rails on your breadboard. The onboard pins connect directly to your breadboard without extra wiring, and the compact design fits neatly alongside your other components.
These modules are super convenient if you run multiple breadboard projects or want backups on hand. They strip away the complexity of managing power distribution, so you focus on the actual circuit design instead of hunting for the right voltage regulator. Note that this is just the power module itself, so you'll need your own breadboard and input power source.
