Connector

Function

Description
J6Provide primary SPI, SSN, and PWM signals to compatible EVMsJ6 includes the MISO, MOSI, SCK, SSN0-3, PWM1, PWM2, GPIO-0, and ground pins.
J9Provide additional control signals to EVMsJ9 includes SNN4-5, PWM3-4, CANH-L, UART_RX-TX, GPIO1-4, PWM3-4, and GND-ISO, which is the ground of the EVM attached.
J1

Micro-USB connector to PC

Connector that uses Micro-USB cable to connect to the PC for GUI control.

J3

CAN0 bus signals that are generated from UART signals

J3 has CAN0_H, CAN0_L, V-ISO (5V), and GND-ISO, which is the ground of the attached EVM. The UART RXD and TXD signals are sent to an CAN-Transceiver to general the differential signals for CAN0 bus. J3 is a standard 100 mil header that can be used as test points or can be used to connect to an EVM by a cable harness.

J4UART signalsJ4 are the single ended UART TXD and RXD signals that are from the MCU. J4 is a standard 100 mil header that can either be used as test points or can be used to connect to an EVM by a cable harness.

J8

All SPI signals

J8 has all the SPI signals put together in one location for probing signals. It includes MISO, MOSI, SCK, SNN0-5, and GND-ISO. J8 is a standard 100 mil header that can either be used as test points or can be used to connect to an EVM by a cable harness.

J12

All PWM signals

J12 has all four PWM signals (PWM1, PWM2, PWM3, and PWM4) created be the MCU and GND-ISO. J12 is a standard 100 mil header that can either be used as test points or can be used to connect to an EVM by a cable harness.
J2

All GPIO signals

J9 has all five GPIO signals (GPIO_0, GPIO_1, GPIO_2, GPIO_3, and GPIO_4) on the header. J2 is a standard 100 mil header that can either be used as test points or can be used to connect to an EVM by a cable harness.

J10

CAN1 differential bus signals

J10 connects to the differential CAN1 bus which was generated from CAN1 port of MCU that is connected to the CAN transceiver. J10 is a standard 100 mil header that can either be used as test points or can be used to connect to an EVM by a cable harness.

J11

CAN1 single ended bus signals

J11 connects directly to the CAN1 signal ended signals that come from the MCU and go to the CAN transceiver. J11 is a standard 100 mil header that can either be used as test points or can be used to connect to an EVM by a cable harness.

J5

Launch Pad emulator connector

This is allows for the use of the LauchPad™ emulator connections from other LaunchPads.

J7

XDIS110 programming connector

This connector allows for the debugging or programming of the MSP432 device.

J13

3v3 external supply connection

This allows for the connection of an external 3V3 supply that is not generated from the USB 5-V connection.

J15

BOOT-LOADER mode jumper

This jumper is used to place the MSP432 in boot-loader mode when an update to the firmware is needed.

Table 1-2 Test Points
Test PointDescription
GND (TP9, TP10, TP12)

These test points are connected to the GND connection from the PC through the USB cable.

GND-ISO (TP20, TP21, TP22, and TP25)The test points are connected to the isolated grounds that connect to the secondary side of the digital isolators the the isolate 5-V supply. GND-ISO connects to the GND connections of the EVMs.
V-ISO (TP24)

This test point connects to V-ISO, which is an isolated 5 V that power the digital isolators and can be used by EVMs as an external 5-V supply.

VREF+ (TP11)

This test point connects to reference voltage of the MSP432.

nHIG (TP6)

This test point connects to the inhibit pin of the MSP432.

VDDC (TP7)This test point connects to the VDDC pin of the MSP432.
