I have an easyweb II development board but I don't have the AC adapter. I have a universal adapter, does anyone know what the right polarity is for the board? Is it positive inside negative outside, or positive outside negative inside? I'd really appreciate any help thanks
see:
positive is the pin, negative the sleeve. it also has a diode on the input, very sensible. If you connect it incorrectly, it won't work, and no damage is done.
Would be nice if a lot more designers did this, along with a power LED and resistor. That would be asking too much. :-)

And a capacitor, so you could run it from an AC-output adapter :-)
:-) and a full wave bridge?

That's basically how the Atmel ATK500 is layed out.

Which simply means moving it from the wall-wart to the unit.
