STMicroelectronics STM32H7 Nucleo-144

UM2407 Rev 1 33/48
UM2407 Hardware layout and configuration
47
All the other solder bridges present on the STM32H7 Nucleo-144 board are used to
configure several I/Os and power supply pins for compatibility of features and pinout with
the target STM32H7 supported.
The STM32H7 Nucleo-144 board is delivered with the solder bridges configured, according
to the target STM32H7 supported.
SB71, SB73
(PE6)
ON, OFF PE6 is connected to SAI_A_SD (D59 of CN9)
OFF, ON PE6 is connected to TIMER_A_BKIN2 (D38 of CN10)
SB67 (PE2)
ON
PE2 is connected to SAI_A_MCLK (D56 of CN9).
QSPI_BK1_IO2 cannot be used (D31 of CN10).
OFF PE2 is used as QSPI_BK1_IO2 (D31 of CN10).
SB53 (PC2) and
SB60 (PF10)
ON
ADC_IN are connected to A4 and A5 (pin 9 and 11) on ST Zio
connector CN9. Thus SB55 and SB62 must be OFF
OFF
ADC_IN are connected to A4 and A5 (pin 9 and 11) on ST Zio
connector CN9. Thus SB55 and SB62 can be ON (I

C)
SB65 (PF11) OFF
On NUCLEO-H743ZI2 and NUCLEO-H753ZI, PF11 is used
only as GPIO on ST morpho connector (CN12) and must not
be used as ADC_IN.

SB55 (PB9) and SB62
(PB8)
ON
PB9 and PB8 (I2C) are connected to A4 and A5 (pin 9 and
11) on ST Zio connector CN9. Thus SB60 and SB53 must be
OFF
OFF
PB9 and PB8 (I2C) are not connected to A4 and A5 (pin 9
and 11) on ST Zio connector CN9.
SB28 and SB70 (PE9)
ON, OFF
PE9 is used as TIMER_A_PWM1 (Pin 4) on ST Zio
connector CN10.
OFF, ON
PE9 is used as COMP2_INP (Pin 15) on ST Zio connector
CN9.
SB37 (PF12) and
SB38 (PF4)
OFF, ON
ADC_IN is connected to A6 (pin 7) on ST Zio connector
CN10.
PF12 must not be used as ADC_IN (SB37 must be OFF)
SB48 (PF5) and SB49
(PF13)
ON, OFF
ADC_IN is connected to A7 (pin 9) on ST Zio connector
CN10.
PF13 must not be used as ADC_IN (SB49 must be OFF)
SB50 (PF14) and
SB54 (PF6)
OFF, ON
ADC_IN is connected to A8 (pin 11) on ST Zio connector
CN10.
PF14 must not be used as ADC_IN (SB50 must be OFF)
SB5
OFF
NUCLEO-H743ZI2 and NUCLEO-H753ZI support 1V8 and
3V3 for VDD_MCU. Thus U10 level shifter is needed and
SB5 must be OFF.
ON
If the MCU is supplied with 3V3, U10 can be by-passed and
SB5 can be ON.
