The RedBoard development platform from SparkFun 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 have 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 voltage ranges from 7 to 15 V_DC.
