Available in full industrial temperature (-40º to +85ºC) versions, the rugged Tetra board meets MIL-STD-202G specifications for mechanical shock and vibration. A heat sink is standard on all models of the Tetra. A latching Ethernet connector provides additional ruggedization for use in extremely harsh environments. Transient voltage suppression (TVS) devices on critical I/O ports provide enhanced electrostatic discharge (ESD) protection for the system. Shown here is a look at some of the standard models of the EPC-2700 Tetra that are stocked at DigiKey. There are three different model options; all three feature the quad-core i.MX6Quad CPU. Two of the models have a Mini PCIe socket and a SATA port, the other has an mSATA socket. The Evaluation model includes the on-board MRAM and 8 GigaByte eMMC memory. Also available from DigiKey are common accessories to enable system development: power supplies, cable kits, hard drives, Solid State Devices, and a number of expansion boards and mini PCIe expansion modules. Tetra is available off-the shelf for immediate testing and system prototyping. Use as­-is for production or contact VersaLogic for modified COTS versions with different memory options, or full custom alterations to meet the customer's specific production requirements.
