Diamond Systems


Gemini from Diamond Systems is a COM Express Compact type 6 carrier board and SBC with PCI/104-Express and minicard I/O expansion. Feature-rich GEMINI offers the highest performance in a compact 4.0 x 4.0″ / 102 x 102mm size, with its combination of COM Express CPU module and full support for PCIe/104 type 1 connectivity (PCI-104 up to 4 modules, PCIe-104 x1 up to 4 modules, and PCIe/104 x16 if supported by the installed COM). Gemini is designed to support any COM Express Compact (95x95mm) type 6 module, from Apollo Lake to Core i7 to Xeon and Ryzen.

Diamond Systems’ Gemini is available as a complete SBC featuring the 11th Generation Intel Core i7 1185G7E “Tiger Lake” processor with up to 64GB SODIMM memory and -40 to +85°C operation.

Gemini as a carrier board provides flexibility in choosing your preferred COM from among dozens of manufacturers around the world. The Gemini carrier offers early access to the latest generation of x86 processors as well as longer product lifecycles by virtue of processor independence.

The COM Express module mounts on the bottom side of the board, with a heat spreader below it serving as a mounting platform and thermal solution. The PCI/104-Express, minicard, and M.2 expansion sockets are on the top side.

The 4.0×4.0 inch (102x102mm) board size maximizes PCB coastline for I/O connectors in the smallest feasible size for the feature set. The combination of latching I/O connectors and a thicker PCB offers superior resistance to shock and vibration.

Gemini offers several options for mass storage. An M.2 2242 socket supports SSD up to 512GB using SLC, MLC, and TLC technology. A SATA connector can be used to connect to an external SSD.

Windows 10 64-bit and Ubuntu Linux 64-bit OS support are available.

  • A PCIe/104 Type 1 socket supports OneBank PCIe x1 I/O modules as well as full PCIe x16 high performance graphics and expansion modules (with Xeon module installed)
  • A PCI-104 socket supports up to 4 PCI-104 I/O modules
  • A full-size minicard socket supports PCIe and USB minicards
