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.
