Features:
This is the new SainSmart Starter Kit， developed specially for those beginners who are interested in Arduino or raspberry pi. You will have a complete set of Arduino\'s most common and useful electronic components. What\'s more. We will offer you a detailed tutorials including project introduction and their source codes(Contact us via Ebay message).You may learn about Arduino through using these basic projects. This kit will help you control the physical world with sensors.
Sainsmart UNO R3 Board MEGA328P ATMEGA16U
Revision 3 of the board has the following new features:
1.0 pinout: added SDA and SCL pins that are near to the AREF pin and two other new pins placed near to the RESET pin， the IOREF that allow the shields to adapt to the voltage provided from the board. In future， shields will be compatible with both the board that uses the AVR， which operates with 5V and with the Sainsmart Due that operates with 3.3V. The second one is a not connected pin， that is reserved for future purposes.
Stronger RESET circuit.
Atmega 16U2 replace the 8U2.
