* The Beagles are tiny open-hardware (you could make one yourself), open-software computers that plug into whatever you have around the house. * Beagles mean big functionality in small packages because these little PCs can be used for all kinds of applications you've been tinkering with... and can handle many of the same tasks as your desktop PC. * The Beagle family is happiest when helping students to learn programming, hobbyists to push the bounderies of DIY and developers move to production quickly without excess noise, expense or bulk.

* Debugging serial port - a root-level session is initiated to this serial port at power up. It can be accessed as a 3.3V serial port, 8-N-1, no handshaking. * Android buttons - these duplicate the functions of the hardware buttons on many Android-based tablets and phones. In Android programming, these buttons have a special function. * GPIO - four 3.3V GPIO pins. * SPI - two dedicated SPI peripheral headers. J6 is the SPI2 peripheral; J7 is the SPI0 peripheral, which is also broken out to the appropriate pins on the Arduino-ish headers. SPI0 pins also provide access to two more UARTs and external interrupts, as well. * Arduino-ish headers - these pins closely follow the functionality of the pins on standard Arduino-compatible boards: I2C, SPI, UART, PWM, and ADC. The mapping is the same as it would be on a standard Arduino-compatible, as well, making it easy to convert Arduino shields to work with pcDuino.
