DFRduino UNO R3 - Arduino Compatible

The DFRduino UNO R3 is a compact microcontroller board fully compatible with the Arduino Uno and Arduino IDE. It uses the ATmega328 and provides 14 digital input and output pins, 6 of which can function as PWM outputs, as well as 6 analog inputs. Running at 16 MHz, it delivers stable performance for a wide range of projects. A USB connection makes programming simple, and the DIP package microcontroller can even be removed or replaced when needed.

To make building easier, the board features color coded headers with red for power, blue for analog and green for digital. This makes it straightforward to connect sensors and shields without confusion, especially when used with DFRobot sensor cables. The DFRduino UNO R3 operates at 5V and can be powered through USB or an external 7 to 12V supply, which provides flexibility for both prototyping and standalone use.

Because it is based on open source hardware, the DFRduino UNO R3 is a versatile tool for interactive electronics. From robotics and automation to creative installations, it combines reliability, affordability and ease of use in one board.
