The BVR is suitable for anybody looking for an inexpensive, convenient method to supply regulated +5 volts to a breadboard. Building a regulated supply each time you do a design is a hassle, but 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 accept 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.
We recommend that the BVR be powered by an AC adapter with 6V DC output (tip positive). Alternately, a 9 volt battery clip can be installed to allow the use of a standard 9V battery.
