board of education Rev D questions
I have two questions......
I have the board of education Rev D. If i put an external power of 12v on the bread board, not the pins or the ground on the board, would it damage the board?
if not, would i be able to use the 2N3904 transistor with that much voltage??
Thank you in advance

Why would you need to use a 2N3904?· If you're switching power to some device that runs off 12V, you would need a switching transistor of some sort.· A 2N3904 could certainly handle 12V up to a few hundred mA.· There's a good discussion of this in Nuts and Volts Column #6.· Use the Resources tab on the main Parallax webpage to find a link to the Nuts and Volts Columns index.
thank you....I will check out that Nuts and Volts section.
@mod sorry about the topic name, i realized i didn't set one after i submitted the post
