ATMEGA328 pinout

I would like to know which pins are connected to the output of the Arduino.

For example:

  • PC6 is digital 12
  • PB5 is analog 13
  • etc...
5

Image searching for the term "arduino uno pinout" reveals a better pinout diagram.

I prefer this image, as it combines the arduino pin numbers and PWM capabilities, with the names and functions from the datasheet.

Or you could simply look at the Arduino Uno schematic, which has everything you should ever need to know.

Updated: Pins PB6 & PB7 while available as I/O pins (D6 & D7) are committed to the external crystal on this board and not brought out to the connectors.

  • That is not true: you cannot find a connector for XTAL for instance. – jfpoilpret Mar 19 '17 at 9:43
