The BPG4 PCI express backplane is a small form factor backplane designed to fit into a small chassis or embedded in an OEM machine. The small or shoebox form factor also provides the capability for rack mount computer and storage system designs to support multiple small form factor backplanes / single board computers within a single enclosure.
The BPG4 PCI Express backplane supports a single or dual-processor SBC and up to three standard PCI Express plug-in I/O cards.
Small form factor (SFF) backplane supports one PICMG 1.3 graphics-class system host board
Three PCI Express option card slots
PCIe card slot configurations: one PCIe x16 mechanical/x16 electrical and two PCIe x8 mechanical/x4 electrical
Optimized for use with Trenton high-performance PICMG 1.3 system host boards
Two 10/100/1000Base-T backplane Ethernet ports
Four USB 2.0 backplane I/O connections
ATX/EPS, +12V AUX vertical and right-angle input power connector configuration options
