Hi,
I would like to control some relays with the digital out ports.
What's the maximum current on those outputs ?
Best regards,
PG

25 mA
You can not power relays directly with the digital i/o. You will require a switching transistor. Or, you can purchase either an i2c relay device. Or a arduino relay shield. Both you can find on eBay
enthousiastic to start off...
Yeah, to play it safe I was gonna use a transistor, though it would
be easy to just hook a relay up to the board as I do with Arduino.
Anyway congratz with this awesome product upon many of us have
been waiting for.

But when i do a lot of tricks one of the 2 transistors get warm.
The VR's will get skin-burning-hot so watch out! Maybe add a fan to it, like someone did on here. It was a brilliant idea! A little fan from the computer store.
