Newbie- Why no seperate servo battery on BOE?

wabbit

I am a complete NOOB.

A little about me:
Experience:
I bought the BOE bot kit and have been going through it and the: What is a microcontroller book.
programming experience:limited to the stuff they teach in middle school to make simple games and plot points etc.
electrical experience: bought Understanding Electricity book by Tab. I understand resistors, leds, capacitors, relays/ switches·a little.·- got to the part about transistors and got stuck. I've made silly little christmas ornaments with some leds, a resistor and a 9v battery.
Mechanical: Used to race rc cars. experiened with servos linkages, gears etc. not really worried about this part

So, I've been reading a lot about controlling servos with·a basic stamp. Almost everything I read recommends using a seperate power source for the servos from the Microcontroller.·

How does the Board of education deal with·this so that there is only one input source?

thanks in advance

It doesn't really although there are provisions (a jumper) to run the servos directly off the battery or other power source while the Stamp and other logic has a 5V regulator. Typically the external power source is 6 to 7.5V and that's enough "head room" for the regulator to do its work.

On the BOE, you can always put header pins in the breadboard area and provide a separate power source for the servos. You just have to be sure to connect the grounds (Vss) together.
