Module Board-to-Board Connector Pinout

The Intel® Joule™ module interfaces with the expansion board through two high-density, board-to-board connectors labeled J6 and J7 on the expansion board. The default pin usage of J6 and J7 refers to the vantage point of the expansion board. For example the +VBUS signal originates in the expansion board and is delivered to the module; therefore, +VBUS is an output from the expansion board.
Unless otherwise noted, all I/O signals operate at 1.8 VDC (with the exception of industry standard buses and protocols) each of which must operate within their defining specification parameters.
