| * On the Cerebot 32MX7, this connector provides access to the I2C signals, power and ground for I2C1. |
| * On the Cerebot MX7CK, this connector provides access to the I2C signals, power and ground for I2C2. |
| EEPROM is changed to this port on the MX7CK |
| 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. |

| #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. |
| JP11 - Programmer Serial Select (MX7CK only) |
| * Remove the jumper to disconnect the USB serial converter's connection to the |
| MCLR pin. Disconnecting this when using the built in debugger is recommended. |
| JP17 - Do Not Use |

| * On the Cerebot 32MX7, this connector provides access to the I2C signals, power and ground for I2C2. |
| * On the Cerebot MX7CK, this connector provides access to the I2C signals, power and ground for I2C1 + INT3/4. |
| J8 - I2C port daisy chain connector |
| * On the Cerebot 32MX7, this connector provides access to the I2C signals, power and ground for I2C1. |
| * On the Cerebot MX7CK, this connector provides access to the I2C signals, power and ground for I2C2. |
| EEPROM is changed to this port on the MX7CK |
| 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. |

| /* |
| 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. |
| JP11 - Programmer Serial Select (MX7CK only) |
| * Remove the jumper to disconnect the USB serial converter's connection to the |
| MCLR pin. Disconnecting this when using the built in debugger is recommended. |
| JP17 - Do Not Use |
