I am getting confused here while making the decision of the arduino required for my project.
I need 6 analog pins minimum and I2C communication as well.
Initially i planned to use arduino pro mini, looking at hardware i see there are 8 analog pins (A0 to A7) but when i look into details and comparison or any other documentation i see that only 6 analog pins are mentioned.
Now i am confused where is the problem, please help.
The Pro Mini's have all 8 analog inputs available. Some documentation may be copy-paste from the Uno, which doesn't break out those pins (since some Uno's use the DIP package, which doesn't have A6 and A7).
You can see the pins marked on the back of the board (note that some clones have different layouts)
