 Bigger Bigger  Smaller Smaller  Reset Reset

Hi folks.

Maybe a silly question but here goes:

My freetronics Etherten card.

The display I have just now says it doesn't work with the USB voltage and needs external power.

Terrific.  The main board has a 2.1mm socket but nowhere does it say which is the + and -.

I'm guessing centre + but you know what thought did.

I don't want to plug it in and watch all the magic smoke escape.

Anyone?

The schematic shows it is center-pin positive (pg 2).

Of course, since this is a Freetronics board, maybe you should ask in their support forums?

Thanks James.

I was trying to navigate their site and was getting lost and confused (hmmmm.....) with the layout and how it kept looping back to pages I had been.
