PCIe 3.0, PCIe 2.0 and PCIe 1.1 Interface Differences
Single board computers such as the JXT6966 and JXTS6966 support a wide variety of PCI Express option card interfaces
. Embedded motherboards like the NTM6900 and WTM7026 feature multiple PCI Express option card slots and BPC7041 and BPC7009 backplanes are examples of PICMG 1.3 backplanes with built-in PCI Express 2.0 embedded computing hardware support.
