Description
The Harrier is an extremely small and rugged SWaP-optimized embedded computer. It has been engineered and tested to meet the industries’ need for smaller, lighter, and lower power embedded systems. Slightly larger than a credit card and one inch thick, the Harrier is a member of VersaLogic’s small, ultra-rugged embedded x86 computers. Equipped with a powerful dual- or quad-core Intel “Apollo Lake” processor and soldered-on ECC RAM, the Harrier is designed to withstand extreme temperature, impact, and vibration.
Up to 8 GB of soldered-on Error Correcting Code (ECC) memory is available for high-reliability applications. ECC memory is beneficial in environments where single bit memory errors may occur, such as with cosmic ray interactions which increase dramatically with altitude.
A TPM 2.0 chip is included for hardware-based security.
On-board I/O includes dual Gigabit Ethernet, one USB 3.0 and four USB 2.0 ports, and two serial ports. SATA interface, eMMC Flash options, and a microSD socket provide a range of data storage options. Dual Mini PCIe sockets accommodate plug-in A/D, Wi-Fi modems, GPS receivers, MIL-STD-1553, Ethernet, Firewire, and other mini cards.
The Harrier, a member of the VersaLogic EPU product family, is designed and tested for full industrial temperature (-40º to +85ºC) operation and meets MIL-STD-202H specifications for shock and vibration. It also features on-board power conditioning for dependable operation from nominal 12V sources.
VersaLogic’s 10+ year product life support programs ensure long-term availability. This avoids expensive upgrades and migrations that come from short, disposable lifecycle products.
