View Arduino Uno Circuit Diagram Images. Although other arduino microcontroller boards are available, the uno continues to be the standard for many projects. Arduino may make changes to specifications and product descriptions at any time, without notice.

Here the arduino uno schematic diagram (click to enlarge):about arduino uno:the arduino uno is really a microcontroller board based on the atmega328. I used the jlcpcb website to make my prototype board. It also explains the role of atmega328 block diagram.

I think you are looking for a hobby pcb design software called fritzing.

The board is equipped with sets of digital and analog input/output (i/o) pins that may be interfaced to various expansion boards (shields) and other circuits. Arduino uno pinout for circuit diagrams using 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. Download circuit schematic for your semester or final year project for free, these schematic diagrams are fully tested and verified in the lab.
