Breadboard Power Supply Module

[Click the image to enlarge it]

The 3.3V/5V output MB102 Breadboard power supply module is an easy to use, most useful breadboard component that can be added with any breadboard related projects where 5V, 3.3V or both power requirements are required. Its ease of use allows users to connect any DC power supply unit that has 6.5-12 VDC power output from a barrel jack. The board has two independent channels of power output for breadboards. These power channels can be independently configured for 3.3V, 0V, and 5V operations.

The module also offers a push switch to turn OFF and ON the entire power supply module.

An additional feature is a USB input with two 5V, two 3.3V, and 4 GND pinout for additional power pin requirements.

The power LED will notify the user of input power availability status.
