The RedBoard is an alternative to the Arduino Uno R3. It uses the Uno's Optiboot bootloader and the R3 shield pins, but instead of an ATmega16U2 for the USB interface, RedBoard uses the tried-and-true FTDI FT232RL that the older Arduino boards had.
The RedBoard also replaces the large USB connector with a USB Mini-B connector. Programming RedBoard with Arduino IDE is otherwise the same as with the Uno: 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 of the Uno: 14 Digital I/O pins with 6 PWM pins, 6 Analog Inputs, UART, SPI and external interrupts. It also has the SDA, SCL and IOREF pins that first appeared 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 7V to 15V DC.
