Atmel SAMA5D4 Xplained Ultra demo Board is a fast Prototyping and Evaluation Platform for Cortex-A5 Microprocessor-based design


Introducing the Atmel® | SMART ARM®-based SAMA5D4 Xplained Ultra demo board. This evaluation kit is a fastprototyping and low-cost evaluation platform for Atmel’s SAMA5D4 Cortex®-A5-based microprocessor (MPU) design. You can download a Linux distribution from linux4sam.com that includes the Linux Kernel 3.10 with LTS (long-termsupport). The build incorporates both Linux Mainline and Yocto support. An Android KitKat port will be available in December 2014 on (w w w.AT91.com/android4sam). For bare-metal developers not using an operating system, Atmel offers a complete C software package including many examples to get you started fast.

The board comes with an HDMI port and a rich set of ready-to-use connectivity and storage peripherals. There are expansion headers for easy customization, including the headers for Arduino Shields and Xplained Wings. You can use the USB device connector to power the board as well as to program and debug it. Last but not least, the SAMA5D4 Xplained Ultra embeds a unique MAC address and serial number which will ease the connection to an Ethernet network.

Power Source

Several options are available to power up the SAMA5D4-XULT board.

The board can be :

  • USB-powered through the USB Micro-AB connector (J11 - default configuration).
  • Powered through an external AC-to-DC adapter connected via a 2.1 mm center-positive plug into the optional power jack of the board (J4). The recommended output voltage range of the power adapter is 5V at 2A.
  • Powered through the "Arduino" shield.
  • Powered through the USB Micro-AB connector on the Atmel Embedded Debugger (EDBG) interface (J20).

Power up the Board

Unpack the board, taking care to avoid electrostatic discharge. Connect the USB Micro-AB cable to the connector (J11). Then connect the other end of the cable to a free USB port of your PC.
