Project Portable DC power voltage regulator for Arduino, XBee, robot project or electronics project that require either 5V or 3.3V or both. This portable voltage regulator included On/Off switch, and indicator LED. The regulator is also included 1N4001 diode for circuitry protection. The PCB has the footprint of 0.8" x 1.18". And it is unique because It is installing on top of 9V battery holder.(with a small piece of double-sided foam tape.) The PCB could also be used with 1.5V 2x2 AA Battery Holder (Jameco #216179) by installing the PCB in the same manner as installing it on top of 9V battery holder as mentioned eariler.
