Building a regulated supply each time you do a design is a hassle; with the BVR you just plug in and go.
The Breadboard Voltage Regulator (BVR) is a convenient and practical way to power your proto board or breadboard project.
The BVR is a regulated 5 Volt supply that is capable of outputting up to 500 mA of current.
The BVR has been specially designed to mount onto the power rails of a standard breadboard and accepts any standard 2.1 mm barrel plug found on most AC adapters.
Should you need a more portable power solution; the BVR can also be powered by a 9 Volt battery.
