SparkFun RedBoard Programmed with Arduino

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, the stability of the FTDI, 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. The 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 15 VDC.
