View Arduino Uno Schematic Pinout Images. This arduino uno pinout diagram reference will hopefully help you get the most out of this board. The customer must not rely on the absence or characteristics of any features or instructions marked reserved or undefined. arduino reserves these for future definition and shall have no responsibility.

The nano is inbuilt with the atmega328p microcontroller, same as the arduino uno. In the arduino uno pinout, you can find 5 gnd pins, which are all interconnected. Added sda and scl pins that are near to the aref pin and two other new pins placed eagle files:

As most of you might have known that in order to program a the detailed description of each feature is out of the scope of this post but will be discussed in detail later in the next post.

Added sda and scl pins that are near to the aref pin and two other new pins placed eagle files: They operate at 5 volts. So in this tutorial we will be looking into the schematic of arduino uno, modify it a little to our needs, make a pcb out of it and solder the required components first of all let's talk about the changes that i am gonna make in the original arduino uno schematic that you can download form the link below. In this guide, learn about arduino nano pin outs and diagrams.
