2.3 Assembly Instructions

For assembly of the J7EXPA01EVM add-on module with the J721EXCPXEVM and J784S4XEVM systems, follow the instructions and illustration below.

  1. If assembling with previously used base EVM, then make sure all power cables and other accessory cables are removed. The EVM must be configured similar to as originally delivered.
  2. Orient the EVM such that the processor is facing downward. The expansion connectors of the EVM must be facing upward.
  3. Remove the four stand-offs in the area of expansion connector to the washer, leaving the threaded stand-off still attached.
  4. Install the J7EXPA01EVM module by aligning the mounting holes and mating connectors. Press firmly to make sure the connectors are seated.
  5. Re-install the four removed stand-offs, but without the thin washer.
    Note: The washer is to help level the board accounting for an expansion board PCB thickness.
