8 Slot Connectors (PCIe, mPCIe, mSATA, PCI)
8.1 PCIe Connectors
The mITX boards supports one PCIex16 (16-lanes), one miniPCIe and one mSATA in mPCIe slot.
The Flex boards supports one PCIex16 (16-lanes), one PCIex2 (2-lanes) in a x16 slot and one PCIex1 slot.
The PCIex16 port can be used for external PCI Express cards inclusive graphics card. (On the Flex boards it
is located nearest the CPU). Maximum theoretical bandwidth depends on the chipset, Q87 / H81 support up
to PCIe 3.0 / PCIe 2.0, so Q87 support 8 Gbps effectively for each lane and direction, 256 Gbps in total for
16 lanes, while the H81 support 4 Gbps effectively for each lane and direction, 128 Gbps in total for 16
lanes.
The PCIex2 (in a x16 slot) (only on Flex board) can be used for external PCI Express cards inclusive graphics
card. It is located fares away from CPU. Maximum theoretical bandwidth is 4 Gbps effectively for each lane
and direction, 16 Gbps in total for 2 lanes.
The PCIex1 (only on Flex board) can be used for external PCI Express cards inclusive graphics card.
Maximum theoretical bandwidth is 4 Gbps effectively for each direction, 8 Gbps in total.
One miniPCIe (PCIe 2.0) port (mITX boards only) supporting mPCIe cards.
One miniPCIe (mSATA) port (mITX boards only) supporting mSATA cards.
miniPCIe slots are equipped with one USB 2.0 port. The USB connected to the mSATA slot do not support
WAKE function.
