FMC (VITA 57.1)

High Pin Count (HPC) 400 I/O high-speed array system

Mechanically compatible Low Pin Count (LPC) 160 I/O can also be used with any of the form factors detailed in the standard  （Zedboard采用的就是这种接口）

FMC+ (VITA 57.4)

High Serial Pin Connector (HSPC) with 560 pins (provides 24 GT interfaces)

High Serial Pin Connector extension (HSPCe) with 80 pins (provides additional 8 GT interfaces; this connector is optional)

分为 FPGA Baseboard Side（female） 和  Mezzanine Card Side （male）

特点是比较贵！

PMC ： (PCI mezzanine cards )

标准连接器

插针 : terminal strips 和 socket strip，俗称排针和排母。间距2.54mm 2.0mm 1.27mm。

 Shrouded Terminal Strip 能防止插错位，配合带鼻子的排母能防反插。
