@graynomad, Indeed this old diagram is still in use. I am using it to compare to the Atmel (now Microchip) E70 Explained's "Ardunio" pinout set which was "claimed" to be compatible with Arduino Due R3, and it is NOT! With Microchip's takeover of Atmel this product is probably a dead horse (E70 MCU).
Note that many people/companies use a similar format for showing pinouts(see some of the Chinese flight controllers). Do you know of a modifiable template of your diagram? I'd like to make one for the SAM E70 Explained.
Thanks!
