6.13 Motor control
In order to be compatible with X-NUCLEO-IHM09M1, X-NUCLEO-IHM07M1 (L6230) and X-
NUCLEO-IHM08M1 (STL220N6F7) motor-control shields, the user must fit CN11 and CN12
(Samtec TSW-135-07-x-D), and set solder bridges according to
Table 15.

Description
SB1 (3V3_PER)
(Only on MB1363
Rev.C)
ON Peripheral power 3V3_PER is connected to 3.3V.
OFF Peripheral power 3V3_PER is not connected.
SB2 (3.3V)
ON Output of voltage regulator ST1L05CPU33R is connected to 3.3V.
OFF Output of voltage regulator ST1L05CPU33R is not connected.
SB103, SB104
(GPIO)
ON
PD8 and PD9 on STM32H7 are connected to ST morpho
connectors CN11 and CN12. If these pins are used on ST morpho
connectors, SB16, SB17, SB15 and SB94 must be OFF.
OFF
PD8 and PD9 on STM32H7 are disconnected from ST morpho
connectors CN11 and CN12.
SB16, SB17, SB12,
SB64 (ST-LINK-
USART)
ON, ON,
OFF, OFF
PA2 and PA3 on ST-LINK STM32F723IEK6 are connected to PD8
and PD9 to enable Virtual COM port for Mbed support. Thus PD8
and PD9 on ST morpho connectors cannot be used.
OFF, OFF,
ON, ON
PA2 and PA3 on ST-LINK STM32F723IEK6 are connected to PB6
and PB7 to enable Virtual COM port for Mbed support. Thus PB6
and PB7 on ST morpho connectors cannot be used.
OFF, OFF, OFF, OFF
PB6, PB7, PA2, and PA3 on ST-LINK STM32F723IEK6 are
disconnected from PD8 and PD9 on STM32H7.
