Battery Path

There are four (4) through-hole connection points near the J4 VDC input connector; a +VBATTERY trace begins here and is routed to the power management device, EU2.
All battery solutions must be completely external to the expansion board except for standard communication and I/O interfaces. The EU2 device serves as the +VSYS voltage regulator.
The battery charger device (EU2) on the expansion board was selected to allow powering of the Intel® Joule™ module from either an external power supply or a battery. The Joule BIOS does not support the ability to enable the EU2 device for battery charging. If battery charging is required, we suggest designing an external solution to power the expansion board that uses a battery charging device designed for the battery chemistry, configuration, and capacity of your target solution.

Product and Performance Information


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.
