The XEM7001 PCB is 3.5” x 2.0” (88.9mm x 50.8mm) with four mounting holes spaced as shown in the figures below. These mounting holes are electrically isolated (disconnected).
The three FPGA-access ports JP1, JP2, and JP3 are located on a 0.1” grid so that the entire board may be attached to a standard prototyping board. The JTAG header JP4 is also on this grid.
