Arduino UNO Pinout Diagram

Really beautiful and useful stuff :slight_smile:

One comment though: on Arduino Uno diagram, the ATMega328 pin 18 is labeled as "PB3" and I believe it should be "PB4". This is both on Arduino Uno board pinout and on ICSP pinout schematic part.

Oh, and on Arduino Uno board pinout, the physical pin 27 serial pin role should be "SDA" instead of "SCL".
