Single Board Computers(SBCs)


Jasper is a COM Express carrier board and SBC for Type 6 Basic (125x95mm) and Compact (95x95mm) modules. It is designed for applications that require ruggedness, a high level of I/O, or extended product lifetime. Notable features of Jasper include:
  • Rugged mechanical design with thicker PCB and latching connectors
  • Wide temperature operation - up to -40 to +85C (depending on the installed COM)
  • Built-in 16-bit data acquisition circuit with autocalibration
  • Dual minicard sockets with PCIe and USB interfaces
  • Dual M.2 sockets for flash memory and network connectivity
  • PCIe/104 expansion socket supporting x16 and x1 links


Saturn was designed from the ground up with a comprehensive set of features to meet the challenges of rugged environments and applications:
  • Memory is soldered down to avoid problems that can occur with commercial style SODIMM type memory modules
  • The 50% thicker PCB increases rigidity and improves reliability of fine pitch and high-ball-count BGA solder joints
  • All I/O connectors are latching for increased ruggedness
  • A bottom-side heat spreader provides more efficient cooling than a traditional heat sink. Processor and memory chips are both thermally connected to the heat spreader. In addition the exterior surface features recessed thermal pads for improved thermal connectivity to the system enclosure.
  • All components are rated and/or tested to ensure reliable -40 to +85ºC operation


Athena IV is a member of Diamond’s 2-in-1 series of SBCs with integrated data acquisition. For applications requiring precision analog I/O, a 2-in-1 SBC is an ideal choice because it reduces the number of boards in the system, resulting in a system that is smaller, lighter, lower cost, and easier to assemble and maintain.
