DFRduino Uno R3

This site has been great fun, but it has run its course, and it is time to move on. Please get what you want from the site before January 1, 2020. Some pages will move to another site but most will go away.

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.
