Pinout of i2c on mini

Forum 2005-2010 (read only) Hardware Interfacing

I've searched numerous forums here and at Sparkfun and cannot find any reference for the pinout of the i2c interface on the Mini. I've seen references to pins 0 and 1 on the regular arduino board, but haven't found much on the Mini.

Also, is there a mini schematic you can point me to that will show the atmega mappings to the Mini pinouts?

Any help towards schematcis and reference material is appreciated.

Thanks,

Landon

There's a schematic here: http://www.arduino.cc/en/uploads/Main/arduino_mini_schematic.pdf

SCL is on analog input pin 5, and SDA on analog input pin 4. So it seems that unfortunately you'll need to solder to those pins on the Mini, since they're not connected to pin headers already.

Thanks for you response. I was arriving at the same conclusion. I should be able to give it a go this weekend. I want to try to read the SparkFun realtime i2c compatible card so I can get the hang of i2c with the Mini.

Have a good weekend.
