Portable 5V and 3.3V regulator


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". It is unique because it's installed 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.

It appears that although this is a 5V and 3.3V project, the kit contains only the 5V regulator, meaning that all users must also purchase the 3.3V regulator separately ? If the kit PCB has the holes and components for the 3.3V regulator function, why isn't the 3.3V regulator included? ALSO, end-users should be advised that the regulators used supply no more than .1A or 100ma to the circuits the regulators are used with. A "kit" is not a kit if it's not complete.
