DFRduino Uno R3

DFRduino Uno R3

The DFRduino Uno R3 is a clone of the Arduino Uno R3. It is not identical, though. The voltage regulators are different. It uses the DIP ATmega328, so you can change it out or use the chip directly in a project. The most visible change is the color coded connectors. They add a little color to the board.
