Is that super necessary? The 232 eeprom can configure that single led to reflect both rx and tx. (I think by default gpio0 is rx and gpio1 is tx but in this case gpio0 will be set to both rx and tx, once i green wire it.) Did you have something else in mind?

Lemor, where'd you go? Im curious about the LED question!

After some creative soldering and green wire work, I got the RX/TX Led working happily. That was a dumb little mistake! Quick little fix in Eagle though and I think Im ready to go. That is unless I have to cram another LED in there....  smiley-grin

Check out the Arduino Nano (and blog post).  It's got RX, TX, and pin 13 LEDs.  smiley

You can pre-order them from Gravitech, who created the board.  They'll ship on June 16th.

Im still working on it... Ive added a reverse protection diode and a method for connecting aref to 3.3. Ive got a batch of the second prototypes in front of me but haven't made the time to finish them up.

If there's still enough interest in it after the metaphorical landslide of recent 'duinos, we will make it available before too long.

Best,
Brian

I think it's a great idea.

btw, I'd like to know whether the logic level of the board is 5v or 3.3v.

Thanks a lot.
