Here is a look at some of the standard models of the EPU-3310 Hawk that are stocked at DigiKey. There are three different processor options; quad-core, dual-core, and single-core. Available in full industrial temperature (-40º to +85ºC) versions, the rugged Hawk board meets MIL-STD-202G specifications for mechanical shock and vibration. A heat plate is standard on all models of the Hawk. There are several thermal options for Hawk including a passive heatsink, Fan to mount on the Passive Heat Sink, and a Heat Pipe mounting plate. Also available is a secondary mounting plate that allows the Hawk to easily mount from the top or bottom of the module.  Latching Ethernet connectors provide 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. Also available from DigiKey are the common accessories to enable system development: Power supplies, cable kits, hard drives, Solid State Devices, and a number of expansion boards and modules.
