Description
SB1 (3V3_PER)
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 & 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.
SB11, SB96, SB15,
SB94 (ARDUINO
USART)
ON, ON,
OFF, OFF
ARD D1 (USART TX) & ARD D0 (USART RX) are connected to PB6
and PB7. Thus PB6 and PB7 on ST morpho connectors cannot be
used.
OFF, OFF,
ON, ON
ARD D1 (USART TX) & ARD D0 (USART RX) are connected to PD8
and PD9. Thus PD8 and PD9 on ST morpho connectors cannot be
used.
OFF, OFF, OFF,
OFF ARD D1 (USART TX) & ARD D0 (USART RX) are disconnected from
PB6, PB7, PD8 and PD9 on STM32H7.
R40 (VDDA)
ON VDDA and VREF+ on STM32H7 is connected to VDD.
OFF
VDDA and VREF+ on STM32H7 is not connected to VDD and can be
provided from pin 6 of CN7 (Used for external VREF+ provided by
Arduino shield).
