Description: At SparkFun we use many Arduinos 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 SparkFun 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 of the latest Arduino UNO R3.
The RedBoard can be programmed over a USB Mini-B cable using the Arduino IDE: Just plug in the board, select “Arduino 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. This version adds an SMD ISP header for use with 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.

Wish it had a micro-b USB connector instead of mini-b.
I used this to replace my Arduino Uno and it works perfectly!
It’s great and made in the USA. Got this for a good discount during the arduino day sale. It still was twice as much as a cheap eBay clone, but it’s four times as reliable. Sparkfun is a company I would highly recommend. Good customer service and friendly staff.
This boards are very reliable, have a great price and great support :D
I was able to quickly set this device with the help of my son. He used one in school which got me interested. Ive been programming for work for the past 10 yesrs so its pretty easy to do basic things or find the code on the internet. I’ve been able to make a display and a countdown timer. With my son’s help we’ve figured out how to use a reed switch and light up different LEDs. End state is a tchometer and speedometer combo for my 1976 RD400. Having fun along the way is a plus.
If you need to set up FTDI based boards in a lab environment where users don’t have permission to install drivers, an administrator can install the driver once, and then make the computer skip installing drivers for every new FTDI device by making a registry change. This solution can sometimes fix this specific problem.
See this page on the FTDI website for directions how.
The SparkFun RedBoard is slightly bigger than the Arduino Uno. Therefore, certain Arduino Uno enclosures will not work with the Redboard due to the narrow tolerances they have. Also, the LEDs are positioned in a different location on the board compared to the Arduino Uno so certain features of some enclosures will not work.
We have found that these Arduino Uno Enclsoures: clear and black ] are not compatible with the RedBoard. The tolerance was too small for the Redboard to fit. We have found that this Arduino Project Enclosure is compatible with the RedBoard.
