YourDuino-RoboRED: Information and How-To

The YourDuino RoboRED is a derivative of the Arduino UNO Microcomputer board. It includes several design and capability upgrades, including Advanced Power capability, and 3-pin connectors for all I/O. See the RoboRED HERE.
See a comparision of RoboRED, Arduino UNO and Robo1 HERE:
See an independent review of the RoboRED HERE:

Features: Logically and software equivalent to the Arduino UNO, with many important improvements:

  • RoboRed-Annotated-900E16.jpg
  • All Digital and Analog I/O pins are provided on 3-pin connectors so you have Ground-Voltage-Signal pins together for Every signal.
  • Original Arduino UNO R3 Connectors and Pinout (Outer yellow connectors) for shields etc.
  • PWM: 3, 5, 6, 9, 10, and 11. Same as Arduino UNO. Provide 8-bit PWM output with the analogWrite() function.
  • Dual operating Voltages: The processor chip can be run at 5.0 or 3.3 V by flipping a small switch (early version) OR moving a jumper. This can accommodate newer peripheral chips that can only operate at 3.3V signal levels. Then the "V" pins on the 3-pin connectors supply 3.3V
  • Advanced Power for your designs with new onboard 5.0V and 3.3V power supplies.
    • Earlier Arduino versions had only 50 mA of current available at 3.3V but now RoboRED provides up to 500 mA at 3.3V
    • An advanced 5.0V switch-mode power supply onboard the RoboRED provides MUCH more 5V power than the original: up to 2 Amps (2000 mA) to power many servos or Relay Boards or powerful LEDs, etc. And the Input Voltage rating is higher at 7-23V.
  • New 4-pin communications pin groups for Serial: (Receive/Transmit/Voltage/Ground) and I2C (Ground/Voltage/SDA/SCL) make it easy to connect to devices such as LCD displays, GPS, RealTime Clock, etc.
  • 6-pin ICSP (In-Circuit-Serial-Programming) connectors on main controller chip (MEGA328P) (Mid-right) and the USB Interface Controller (MEGA16U2) at upper left. NOTE: Pin 1 locations are marked.
  • Better Analog noise levels: Careful layout of Analog input circuits reduces interference from I2C signals on A4 and A5
  • FCC Certification ID: CST-FV140423070 RoHS

Using the RoboRED:

In Arduino IDE Select TOOLS > BOARD > UNO
In Arduino IDE Select TOOLS > SERIAL PORT > (Your correct Serial Port)

Cables / Wires / Devices: The 3-pin connectors on every I/O pin make it easy to connect things. See more about Cables, Wires and Pins HERE.

The RoboRED also has 4-pin connectors for Serial and I2C communications (marked in Blue above).

Problem-Solving for the RoboRED:

If you have a new YourDuino RoboRED, or are experiencing problems uploading software sketches, here are a few tips:

1. Make sure you have the right board type selected. RoboRED is equivalent to an Arduino UNO. In the Arduino IDE software on your computer:
  • Click on Tools, Then click on Board , Then click on ARDUINO UNO . See the example on the right.

  • Turn up your computer's sound output. Plug in the USB cable on your RoboRED. You should hear a sound like "Low-High" when the USB device is recognized. If your RoboRED is recognized you should be able to see it on a port list in the Arduino IDE. See the example on the right. Click on Tools, Then Port: You should see an entry for your RoboRED with a port number (usually Com10 or less) and a label "(Arduino UNO") . Click on that port number.


  • If your RoboRED is not recognized at all you may see the situation in the example on the right: The only Port shown will be COM1 or COM2 and no other ports. Try unplugging and replugging the USB cable. Try another cable
