Hello Folks,

I have finally got the LPC2294 board with Universal Wall Mount Power Supply. I really don’t know how much voltage I should input to the board and the which polarity.

The Power Supply has this output current table.

I know that this is a stupid question but I rally can’t afford loosing my board :frowning:

Thanks in advance

Check the schematic. It might have a bridge rectifier on the input, so the polarity won’t matter. I think that Olimex does that on some of their boards. 6V input should be safe.

Thanks alot for your reply.

I have found that the polarity center positive and it takes 6 VAC

Thanks again
