Figure 6-2. Key Components on the controlCARD - Back
WARNING
When the controlCARD is used in a high-voltage setup, it is the user’s responsibility to confirm that
the voltages and isolation requirements are identified and understood prior to energizing the board
or simulation. When energized, the controlCARD or components connected to the controlCARD
should not be touched. Furthermore, the capacitor C7:A should be removed to minimize the
possibility of leakage current flowing across the isolation barrier of the controlCARD.
Table 6-1. Hardware Connections
Connectors
J1:A
Emulation/UART connector/Power - USB-C connector used to provide XDS110 emulation and USB-
to-UART (SCI) communication through MSP432 logic. S1:A determines which connections are
enabled to the MCU.
The USB-C connector also provides power on the controlCARD.
J1
FSI Header – This header is keyed, contains 2 data lines, and has 3.3-V power.
LEDs
LED1:A
Turns on (red) when 5 V is supplied to the controlCARD
(5 V can be supplied either through the USB-C connector or externally through the HSEC
connector)
LED2:A/LED3:A
JTAG/UART RX/TX toggle indicator (blue)
D1
Controlled by GPIO-31 with negative logic (red)
D2
Controlled by GPIO-34 with negative logic (red)
D3
Turns on (green) when 3.3 V is supplied to the controlCARD
Resistors and Capacitors
R25-R47
ADC RC input filter resistors:
Series resistors which can be used to create an RC filter on the
ADC's input.
C29-C51
ADC RC input filter capacitors:
Optional capacitors, not populated by default, for the ADC input's
RC filters.
