Advantages and capabilities

Compact fanless design

Just under 133 mm X 100 mm X 35 mm, with advanced heat transfer and dissipation from internal components.
Rigid, durable, fanless housing for harsh environments.


Great performance

Utilizing a quad-core Atom processor with unconditionally-efficient heat dissipation, the high performance remains consistent. With up to 32GB of DDR4 memory at a speed of up to 3200MT/s, the processing capabilities are comparable to what’s expected from much larger, more power-consuming, and less affordable computers.


Multiple interfaces

Wide range of capabilities with extended wired and wireless connectivity, Industrial interfaces, and advanced storage and media capabilities.


  • Wired Connectivity: Up to 4 Ethernet ports, optional SFP+ or PoE on FACET card
  • Wireless connectivity: Optional Wi-Fi/BT module and LTE or 5G modem
  • Industrial interfaces: Optional Isolated RS-232/RS-485 + GPIOs on terminal block
  • Storage: NVMe M.2 + SATA M.2 or 2.5” SSD/HDD (up to 2 devices)
  • Media: HDMI + mini Display Port, up to three 4K displays, Optional analog audio in/out
  • USB: 4x USB 2.0 + 2x USB 3.1
