The Mini PCIe card is a small form factor board used to implement the PCI Express interface to expand embedded PC I/O. The card size is 30mm wide by 50.95mm long. The Minicard standard defines a 52-pin card edge connector. The card is based on PolarFire MPF300T-1FCVG484E from Microchip. It provides additional processing power, GPIOs as well as high-speed transceivers to the host. SE50 has an x1 GEN2 PCIe interface as an End Point and JTAG for programming and development. SE50 included 4GB of DDR4 memory and can optionally be fitted with lower cost MPF100 and 200 in the same package.
