The board comes along with Linux 4.1 software packages, necessary cable accessories as well as detailed documents to enable quick start 2 / 10
when getting the goods out of box. It can support -40 to +85 Celsius extended temperature operation for industrial embedded applications. It is an excellent EVM (Evaluation Module) and a good reference design for extensively evaluation, fast prototyping and creating applications that require high efficient computing, display, audio, mass storage, networking, connectivity and more. Hardware Specification The Atmel SMART SAMA5D2 series is a high-performance, ultra-low power Cortex-A5 processor based MPU. It supports multiple memories, including latest generation such as DDR3, LPDDR3, and QSPI Flash. It is particularly well-suited for small control panel/hmi applications and secure IoT gateway/connectivity applications. The AMA5D2 is also ideal for barcode scanners and printers as well as mid-range POS terminals that require PCI. The improved low power features and small package deliver an excellent solution for wearables and other batteryoperated applications.
