I am starting out on my first real project which is based around an Arduino Pro Mini. I tried ‘Place Component’ and looked for the appropriate symbol in the libraries. In the amtel library there are 10 ATMEGA328 symbols listed none of which appear to represent the Pro Mini which I have represented as
(I would appreciate feedback on whether or not this is an appropriate symbol for same or whether I have transgressed some sacred rule of IC representation. )
My next step would, I assume. be to create a footprint for this beast, but try as I might I have been unable to find a datasheet giving the applicable dimensions. One could assume that the pins along the sides are at 0.1" centres but there are a few more dimensions which are better read than guessed. Would someone please point me to a usable datasheet or dimension drawing?
