ACROBOTIC ATmega328P Development Board UNO R3 | Arduino-compatible

Regular price $9.99

This board is a clone of the fantastic Arduino UNO. It is an exact replica, so it has the same functionality, and works in the same way as the official board.  That is, it is able to run the same code, be programmed in the same way, and use any of the shields developed by Arduino as well as 3rd parties.

As for the Arduino UNO R3, it's the latest version of the most popular board from the Arduino family. It includes an improved USB interface chip, an expanded shield header with a 3.3V reference and a RESET pin (making it easily accessible from a shield), and a 500mA fuse to protect anything connected via USB. If also includes circuitry from automatically selecting USB or DC power without using a jumper!

The UNO R3 is pin- and code-compatible with other Arduino board models such as the Duemilanove, Diecimilla, and even older versions. This backwards compatibility allows all shields, libraries, and code to work with the R3 revision. This new version (3rd revision) of the UNO board also has a few minor changes such as additional breakouts for the i2c pins and an IORef pin.
