I am user of FEZ Domino board. I was doing some little project where i used eight digital outputs and leds (leds and appropriate resistors were all the same). I have found that for outputs 2 and 3 voltage seems to be lower than for the rest of the pins (leds lit weaker). Could anyone explain reason for that? I found that pins 2 and 3 are connected with I2C SDA and SCL. Is there any connection between these facts?
Thanks in advance,
