The right hand columns describe the corresponding function to that position.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"JP7-VDDEN\"><\/span>JP7-VDDEN<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>Controls how the main subsystem, including the main MCU\/DSP and supporting digital logic, is powered up, as relates to the digital power rail regulator(s).  Extremely low power consumption can be configured, for example by allowing an synchronized-sleeping mesh XBee device to wake the rest of the board when it needs it.<\/p>\n\n\n\n<p>Usage of the communications (comms) module pin control jumper setting (versus always-on &#8211; see table below) applies to XBee radios of various protocols and frequencies, the Connect ME (CME), the Connect Wi-ME, and the Wi-EM modules.  Anything that fits into the footprints on the board and allows for GPIO control of the corresponding pins in the either the XBee or Connect ME socket footprints.<\/p>\n\n\n\n<p>For the XBee radio footprint, there are still many other control configurations possible by changing which of R69, R70 and R71 are populated.  R71 is the typical default-populated component that connects the XBee DIO1 pin to the board&#8217;s main sub-system power control rail, again, if the jumper noted here is set to allow such control.<\/p>\n\n\n\n<p>The CME&#8217;s socket footprint always has pin 13 (DIO0) connected to this power enable signal, again, if the matching jumper here is set to allow such control.  Other CME socket footprint pins can be configured for power control alternatively using the above mentioned optional resistors and a corresponding software\/firmware configuration of the CME module itself.<\/p>\n\n\n\n<p>Very flexible and configurable.<\/p>\n\n\n\n<p>You can use standard networking and related Python (or whatever code you want) along with a matching configuration of the CME module internal settings to control the DIO pin for power control, with the matching jumper setting.  Controlling the pin can provide very substantial power budget savings.<\/p>\n\n\n\n<figure class=\"wp-block-table\"><table><tbody><tr><td>South (away from XBee footprint)<\/td><td>Always On (e.g. USB to Serial)<\/td><\/tr><tr><td>North (toward the XBee footprint)<\/td><td>1.

The default build configuration, that is, which components are installed by default in a usual board assembly, connects this enable signal to the XBee DIO1 pin.  The CME DIO0 pin is connected always, though need not be used.  Connect\/Wi-EM and Wi-ME pins also apply.

On the screw terminal block (STB), the first (East-most) pin is ground as are pins 3 and 5.  The 2nd pin West from pin 1 is the usual power input.  Pin 4 is a battery power input, for example for a low-power configured solar battery system powering the board.
