Label Function
J4 External Servo Power Connector
This screw terminal connector is used to power the servo power bus from an external
power supply. JP5 and JP8 must have the shorting blocks removed when using this
option for powering the servo power bus.
J5 & J7 Pull-up enable for I2C port #1
These two jumpers are used to enable/disable the pull-up resistors on I
2 C port #1. 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 I
2 C bus should have
the pull-up resistors enabled.
J6 I 2 C port #1 daisy chain connector
This connector provides access to the I 2 C signals, power and ground for I 2 C port #1.
J8 I 2 C port #2 daisy chain connector
This connector provides access to the I 2 C signals, power and ground for I 2 C port #2.
J9 CAN Connector
This connector is used to access the signals for the CAN interface.
J10-J12 Do Not Use.
J13 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.
J14-J15 Motor/Bridge Output Connectors
These are used to connect external loads to the bridges. J14 provides access to the
VMOT1 and VMOT2 signals. J15 provides access to the VMOT3 and VMOT4 signals.
When the bridge circuits are used to form h-bridges, J14 provides access to one h-bridge
and J15 provides access to the other.
J16-J17 Motor/Encoder #1 Connector
J16 is a six pin JST connector that provides connection to VMOT1 and VMOT2 for use as
an h-bridge to drive a motor. These are the same signals as on J14. Connector J16 also
provides access to the two phase inputs to the quadrature encoder peripheral in the
dsPIC microcontroller. J17 is an alternate connector for access to the quadrature encoder
inputs.
J18-J19 Motor/Encoder #2 Connector
J18 is a six pin JST connector that provides connection to VMOT2 and VMOT3 for use as
an h-bridge to drive a motor. These are the same signals as on J15. Connector J16 also
provides access to two pin-change interrupt capable pins on the dsPIC microcontroller.
These inputs can be used to implement a quadrature in softwarer. J19 is an alternate
connector for access to the quadrature encoder signals.
