Expansion Connectors
The MicroBlaze Development Kit board provides a variety of expansion connectors for
easy interface flexibility to other off-board components. The board includes the following
I/O expansion headers (see

Hirose 100-pin FX2 Edge Connector (J3)

A 100-pin edge connector is located along the right edge of the board (see
connector is a Hirose FX2-100P-1.27DS header with 1.27 mm pitch. Throughout the
documentation, this connector is called the FX2 connector.
As shown in
these pins are true, bidirectional I/O pins capable of driving or receiving signals. Five pins,
FX2_IP<38:35> and FX2_IP<40> are Input-only pins on the FPGA. These pins are
highlighted in light green in
signals.
