  • Application

    The Viper is primarily designed to provide a low cost rugged computer for defense and UAV applications, but can be deployed in commercial and industrial applications, as well. The Viper is widely deployed in unmanned robots for hazardous applications, where the computer is exposed to the harshest possible environments, and UAVs, where power, weight and size are the main considerations. The Viper is ideal for applications where it is connected to a variety of I/O such as motors, sensors and cameras that are all enclosed within another enclosure that protects all system functions to reduce the system cost significantly without compromising ruggedness and performance. The S405R may be ordered from the factory with operating systems such as Windows®, Linux® or VMware® pre-installed.
  • General Description

    The S405R Viper is a second-generation rugged, low cost, low power, lightweight Atom™ based computer system. It is designed to provide the lowest power consumption possible in a fully ruggedized, conduction cooled system, operating over a full -40°C to +85°C. The Viper is targeted for applications where an ultra-low power, low cost rugged computer is needed to provide the best possible performance per dollar per watt, utilizing high-density, low cost, rugged interconnects to provide easy interconnect to system I/O and user I/O. 
    The Viper utilizes the latest Intel® Dual Core Atom™ processor with 512KB of L2 cache per core up operating at up to 1.86GHz, and deep sleep capabilities for ultra-low power consumption when not active. To harvest this incredible CPU performance, the CPU is coupled with up to 4GB of 1067 MHz DDR3 SDRAM. The entire Viper system consumes less than 12W total with average of 7W in normal operation. This makes the Viper the lowest power consuming and highest performing fully rugged system in the market.
    The I/O subsystem for the Viper is designed to support a wide array of standard and custom I/O functions. The S405R standard configuration supports four or two Gigabit Ethernet channels (factory option) with TCP/IP offloading engine, one 10/100 Fast Ethernet port, two USB 3.0 ports, three USB 2.0 ports, one removable 2.5” SSD, eight buffered digital I/O lines, one RGB, HD Video and DisplayPort with optional NTSC/PAL video (lose DisplayPort), four COM ports with RS232/422/485 options, and an audio headset jack and a one-watt audio amplifier to drive an 8-ohm speaker directly. Optional additional I/O functions such as, mSATA with write protect and secure erase as a Boot device, quad video capture, CANbus, MIL-STD-1553, Wi-Fi/Bluetooth, FireWire, GPS for data time stamping, and many other I/O functions utilizing the three SAM™ sites are provided.
  • Technology Used

    The Viper utilizes the most powerful Intel® Atom™ Dual Core processor. The CedarView-M® CPU is a 2nd generation Dual Core Atom™ processor with a fully integrated memory controller for the best memory performance possible. This CPU is considered the best performance per watt in the market with protection assured by the Trusted Platform Module (TPM) for secure operation. Also, the graphic engine has the best performance of any Atom™ based integrated video in the market with outstanding performance in 2D and 3D with DirectX™ 10.1 and OpenGL 3.0 support.
  • Cooling

    The Viper is equipped with the most unique cooling system in the industry and is the only system that operates from -40°C to +85°C at full load! Its patent pending cooling approach provides the lowest thermal resistance to the case while providing the highest shock specifications known in the industry. The S405R is a fan-less system and can be mounted directly to a metal surface or be used as a stand-alone system.
