    Product Description

    At SparkFun we use many microcontrollers compatible with Arduino and we're always looking for the simplest, most stable one. Each board is a bit different and no one board has everything we want, so we decided to make our own version that combines all our favorite features. The RedBoard combines the simplicity of the UNO's Optiboot bootloader (which is used in the Pro series), the stability of the FTDI (which we all missed after the Duemilanove was discontinued) and the R3 shield compatibility.

    The RedBoard can be programmed over a USB Mini-B cable and is compatible with the Arduino IDE: Just plug in the board, select "UNO" from the board menu and you're ready to upload code. RedBoard has all of the hardware peripherals you know and love: 14 Digital I/O pins with 6 PWM pins, 6 Analog Inputs, UART, SPI and external interrupts. We've also broken out the SDA, SCL and IOREF pins that showed up on the UNO R3, so the RedBoard will be compatible with future shields.

    You can power the RedBoard over USB or through the barrel jack. The on-board power regulator can handle anything from 7 to 15VDC. Check out the related items below for a compatible wall-wart power supply.

    14 Digital I/O Pins (6 PWM outputs)

    6 Analog Inputs

    ISP Header

    32k Flash Memory

    16MHz Clock Speed

    5.0 out of 5 stars Good markings on the board, love the mini-usb
    Reviewed in the United States on September 14, 2013
    Verified Purchase
    I use this as a secondary Arduino Uno, Programmatically, there is no difference that I can tell. The reset button is in a good location and all the pins are well marked for which are PWM. Take a picture before you put a shield on it, because the markings are not printed on the back side of the board for reference. The Mini-usb is great because it doesn't collide with a shield like the full sized USB plug on the standard Arduino. Also, the Mini-USB is much stronger and solidly mounted (four SMD solder pads hold the housing in place) than the fragile micro-usb used on other boards. The teensy SMD chips give it a nice modern sleek look. I think we have a winner.

    Oh, and it's red which is pretty cool.

    5.0 out of 5 stars My go-to boards for Arduino / Small Electronics Projects
    Reviewed in the United States on April 5, 2017
    Verified Purchase
    The board is slightly less expensive than buying genuine Arduino boards, but you get the quality and reputation of an American made product. I've successfully used Arduino Uno clones from eBay, but I now prefer these sparkfun redboards. They work great every time. The board and the ecosystem created by Sparkfun makes for alot of fun.

    I do appreciate the USB connection is smaller so that I don't have problems with shields that attach.

    If you have Windows 8 this is the Arduino Uno R3 to get because it comes with the drivers installed. If you have ever gone through the hassle of trying to get a Arduino Uno or clone to work with Windows 8.1 , 64Bit you'll know what I mean.

    Pretty much identical to the Arduino Uno, the only difference being it's red and uses USB Mini-B. And since I have more of that kind of cable, it works better for me.
