COM Express modules integrate the core CPU and memory functionality in an embedded computer board. The system buses, video, Ethernet, USB and other I/O capabilities are mapped to one or two high-density connectors on the bottom of the module. The COM Express module is paired with a carrier board that brings out the connectors required for the application.

The PICMG COM Express module specification revision 2.0 defines seven different Types, depending on required features: Type 1 – Type 6 and Type 10. Type 2 is currently the most common pin out.

  • Type 1: single 220 pin connector, 6 PCI Express lanes, 4 SATA, Ethernet
  • Type 2: dual 220 pin connectors, 22 PCI Express lanes, PEG, PCI, IDE, 4 SATA, Ethernet
  • Type 3: dual 220 pin connectors, 22 PCI Express lanes, PEG, PCI, 4 SATA, Ethernet
  • Type 4: dual 220 pin connectors, 32 PCI Express lanes, PEG, IDE, 4 SATA, 3 Ethernet
  • Type 5: dual 220 pin connectors, 32 PCI Express lanes, PEG, 4 SATA, 3 Ethernet
  • Type 6: dual 220 pin connectors, 24 PCI Express lanes, PEG, DDI, 4 SATA, Ethernet, 2 Serial, USB 3.0
  • Type 10: single 220 pin connector, 4 PCI Express lanes, 2 SATA, Ethernet, LVDS, DDI, 2 Serial

Sealevel has the experience to add additional serial, Ethernet, USB and other functionality via PCI Express lanes. Sealevel can help you select the appropriate COM Express module for your requirements and design a COM Express carrier board to the exact specifications for your application.
