Primary Power Source and Grounding

The Intel® Joule™ module requires a primary power source (+VSYS) routed through 12 pins, 6 on each board-to-board connector. Connect all 12 +VSYS lines in common on the Intel® Joule™ expansion board to balance the input current path to the module.
Connect all ground pins common to board ground planes and the module mechanical mounting solution.
Refer to Power Delivery, Signaling, and Reset for module-specific information.

Product and Performance Information

1

Intel's compilers may or may not optimize to the same degree for non-Intel microprocessors for optimizations that are not unique to Intel microprocessors. These optimizations include SSE2, SSE3, and SSSE3 instruction sets and other optimizations. Intel does not guarantee the availability, functionality, or effectiveness of any optimization on microprocessors not manufactured by Intel. Microprocessor-dependent optimizations in this product are intended for use with Intel microprocessors. Certain optimizations not specific to Intel microarchitecture are reserved for Intel microprocessors. Please refer to the applicable product User and Reference Guides for more information regarding the specific instruction sets covered by this notice.
