I found a mistake in the manual for the 3pi

This is not pointing out a typo. It is an actual content error. It says hat 3pis with a serial #>0j5… will have an Atmga 328p instead of a 328. Mine is 0j2… (I don’t have it with me at the moment) and has a 328p.

Hi.

Since you didn’t give the entire serial number I cannot confirm this, but I suspect that your 3pi’s serial number probably has 5 digits in it, so it is a larger number than 0J5840, which was the first 3pi to use the ATmega328P.

My whole serial # is
0J26987
Sorry, I didn’t have my robot with me at the time.
