J7 - I2C port #2 daisy chain connector
 * This connector provides access to the I2C signals, power and ground for I2C port #2.
J8 - I2C port #1 daisy chain connector
 * This connector provides access to the I2C signals, power and ground for I2C port #1.
J9 - CAN #1 Connector
 * This connector is used to access the signals for CAN #1.
J10 - CAN #2 Connector
 * This connector is used to access the signals for CAN #2.
J11 - Ethernet Connector
 * This connector provides access to the 10/100 Ethernet port.
J12-J14
 * Do Not Use.
J15 - Debug USB Connector
 * This connector is used to connect the on-board programming and
    debug circuit to the PC for use with the MPLAB IDE.
J16 - Power supply source select
 * This jumper is used to select the source of main board power.
        Place a shorting block in the upper, ?USB? position to have the
            board powered from the USB device connector, J19.
        Place a shorting block in the center, ?EXT? position to have the
            board powered from one of the external power connectors, J17 or J18.
        Place a shorting block in the lower, ?DBG? position to have the
            board powered from the debug USB connector, J15.
J17 - External Power Connector
 * This is a 2.5mm x 5.5mm, center positive, coax power connector used to 
    provide external power to the board. The optional Digilent 5V Switching
    Power Supply is connected here.
J18 - External Power Connector
 * This is a screw terminal connector used to provide external power to
    the board. Be sure to observe proper polarity (marked near the connector)
    when providing power via this connector, or damage to the board and/or
    connected devices may result.
J19 - USB Device / OTG Connector
 * This is a USB micro-AB connector. It is used when using the PIC32MX795
    microcontroller to implement a USB device or OTG Host/Device.
J20 - USB Host Connector
 * This is a standard sized USB type A connector. This connector is used to 
    connect USB devices to the board when using the PIC32MX795 microcontroller
    to implement an embedded USB host.

J20 - USB Host Connector
 * This is a standard sized USB type A connector. This connector is used to 
    connect USB devices to the board when using the PIC32MX795 microcontroller
    to implement an embedded USB host.
JP1 & JP2 - CAN or Pmod Select
 * These jumpers select microcontroller signals RF12 and RF13 for use with CAN 
    #1 or Pmod connector JF. Place these jumpers in the CAN position to use CAN
    #1. Place the jumpers in the PMOD position to use then with Pmod connector JF.
JP3 & JP4 - Pull-up enable for I2C port #2
 * These two jumpers are used to enable/disable the pull-up resistors on I2C
    port #2. Insert shorting blocks on these two jumpers to enable the pull-up
    resistors. Remove the shorting blocks to disable the pull-up resistors. Only
    a single device on the I2C bus should have the pull-up resistors enabled.
JP5 - CAN #1 Termination
 * This jumper is used to enable/disable the 120 ohm termination resistor for 
    CAN #1. Insert the shorting block to enable the termination resistor, remove
    it to disable the termination resistor.
JP6 - CAN #1 5V0 Enable
 * This jumper is used to enable/disable providing 5V to the CAN #1 connector. 
    Insert the shorting block to connect the board 5V0 supply to pins 9 & 10 of
    CAN #1 connector. Remove the shorting block to disconnect the 5V0 supply.
JP7 - CAN #2 Termination
 * This jumper is used to enable/disable the 120 ohm termination resistor for 
    CAN #2. Insert the shorting block to enable the termination resistor, remove
    it to disable the termination resistor.
JP8 - CAN #1 5V0 Enable
 * This jumper is used to enable/disable providing 5V to the CAN #1 connector. 
    Insert the shorting block to connect the board 5V0 supply to pins 9 & 10 of
    CAN #1 connector. Remove the shorting block to disconnect the 5V0 supply.
JP9 - Do Not Use
JP10 - USB host power select
 * This jumper is used to select which host connector is powered when host power
    is enabled. Place the shorting block in the ?MICRO? position to supply power
    to the USB micro-AB OTG Connector, J19. Place the shorting block in the ?A?
    position to supply power to the USB type A Host Connector, J20.
JP17 - Do Not Use
