This solderless breadboard power supply module makes powering your prototype a snap. With a standard 2.1mm barrel jack, you can power it with a 9-volt battery using a Snap-on connector or a wall-wart. With a convenient ON/OFF button switch with an indicator LED, you don’t have to keep plugging in and unplugging your power source.

The rails are powered separately, so you can have one side at 3.3 volts and the other as 5 volts. There is also an off position for the jumper to break the circuit and not power the rail at all.

The board has a 2 x 4 group of male headers, with 2 sets for 3.3 volts to GND and 2 sets for 5 volts to GND. One of our favorite features is the USB-A port to plug in your USB powered dev boards like an Arduino.

This gives the added benefit of tying the breadboard ground to the development board ground as well. There is a nice feature set on this little board, and it’s a real time saver.
