    IC on Teensy++ 2.0

    Hello, I can't find anywhere what the two pins used for IC communication on the Teensy++ 2.0 are (maybe I haven't looked hard enough). Can you please help me?

    Thanks a lot. I guess I was only looking at the pinout for Arduino software, instead for C language.

    Within Arduino, they are 18=SDA and 19=SCL

    Yep. That's also what they are on any of the T3.x but the T2 and T++2 were different.

    Yup, all the pre-3.0 boards had really different pinouts. The consistent feedback we heard was a desire for the boards to be pin compatible. Starting with Teensy 3.0, we tried to standardize the pinout for all Teensy to closely resemble the conventions set by Arduino Uno, except of course using 3.3V signals.
