The YourDuino compared to Arduino

There are over 100 "Arduino Compatible" microcomputer boards. They may be physically different in size and details but they all have these components:

  • An ATMEL ATMega Microcontroller chip such as a 328, 1280, 2560
  • A Programming Interface (Usually USB) connecting to a personal computer running the Arduino IDE software
  • Compatibility with the Software Sketches uploaded from the Arduino IDE
  • Power inputs from USB, Batteries or plug-in power supplies
  • External connections to various Input and Output devices

Below is theYourDuino RoboRED (link) It is compatible with the UNO (has the same size, connectors, USB interface and functionality). It has several added connectors, features and upgrades. Details are HERE RoboRed-Annotated-900E16.jpg

What About "Arduino Compatibles, Arduino Derivatives, Arduino Clones and Arduino Counterfeits" ??

The Arduino project – both hardware and software – is open-source. The schematics, hardware design files, and source code are all freely available. Arduino is under a Creative Commons Share Alike license. Anyone can duplicate the design or make modifications or additions to it and market the resulting product as long as they, in turn, make all the designs available.

  • Arduino Derivatives: The YourDuino RoboRED and the YourDuinoRobo1 are derivative designs which add functionality and make changes to the original design, and are marked with their own artwork/identification. Another example is the Sparkfun Redboard.
  • Arduino Clones: Are available on Ebay and other sources. They use the exact Arduino open-source design but have their own markings and do not pretend to be original Arduinos.
  • Arduino Counterfeits: (Also regrettably available on Ebay etc) Violate the Arduino Copyrights by copying the Arduino markings and attempt to look 'just like' an Arduino from

What added features does the YourDuino RoboRED and Robo1 provide?

  • USB-to-Serial Transceiver: The Arduino UNO uses an ATmega16U4 microcontroller with custom firmware to convert between USB and serial. The YourDuino RoboRED uses the same USB interface as an Arduino UNO.
  • LED placement is more ergonomic: can been seen easily when a shield is used
  • Built-in Sensor Shield connectors for Servos or other Digital or PWM applications, and 6 Analog inputs
  • Free USB Cable (50cm)
  • Many Additional Power and Ground pins
  • Improved 3.3V power regulator provides up to 500ma
  • RoboRED has an advanced switching power supply that can supply 2A at 5V
  • ATMEL 328 processor can be run on either 5.0 or 3.3V for compatibility with new sensors and devices
