chipKIT™ Pro MX7 Board Reference Manual
This connector is used to connect the on-board programming and debug circuit to the PC for use with the
MPLAB IDE.
External Power Connector
This is a 2.5mm x 5.5mm, center positive, coax power connector used to provide external power to the board.
J17
The optional Digilent 5V Switching Power Supply is connected here.
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
J18
and/or connected devices may result.
USB Device / OTG Connector
This is a USB micro-AB connector. It is used when using the PIC32MX795 microcontroller to implement a USB
J19
device or OTG Host/Device.
USB Host Connector
This is a standard sized USB type A connector. This connector is used to connect USB devices to the board
J20
when using the PIC32MX795 microcontroller to implement an embedded USB host.
CAN or Pmod Select
These jumpers select microcontroller signals RF12 and RF13 for use with CAN #1 or Pmod port JF. Place these
JP1 &
jumpers in the CAN position to use CAN #1. Place the jumpers in the PMOD position to use then with Pmod
JP2
port JF.
Pull-up enable for I2C1
These two jumpers are used to enable/disable the pull-up resistors on I2C1. Insert shorting blocks on these
JP3 &
two jumpers to enable the pull-up resistors. Remove the shorting blocks to disable the pull-up resistors. Only
JP4
a single device on the I
CAN #1 Termination
This jumper is used to enable/disable the 120 ohm termination resistor for CAN #1. Insert the shorting block
JP5
to enable the termination resistor, remove it to disable the termination resistor.
CAN #1 5V0 Enable
This jumper is used to enable/disable providing 5V to the CAN #1 connector. Insert the shorting block to
JP6 connect the board 5V0 supply to pins 9 & 10 of CAN #1 connector. Remove the shorting block to disconnect
the 5V0 supply.
CAN #2 Termination
This jumper is used to enable/disable the 120 ohm termination resistor for CAN #2. Insert the shorting block
JP7
to enable the termination resistor, remove it to disable the termination resistor.
CAN #1 5V0 Enable
This jumper is used to enable/disable providing 5V to the CAN #1 connector. Insert the shorting block to
JP8 connect the board 5V0 supply to pins 9 & 10 of CAN #1 connector. Remove the shorting block to disconnect
the 5V0 supply.
Do Not Use.
JP9
USB host power select
This jumper is used to select which host connector is powered when host power is enabled. Place the shorting
JP10
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.
