STM32U5 Nucleo-144 board (MB1549)
Introduction
The STM32U5 Nucleo-144 board based on the MB1549 reference board (NUCLEO-U575ZI-Q) provides an affordable and
flexible way for users to try out new concepts and build prototypes by choosing from the various combinations of performance
and power consumption features, provided by the STM32U5 microcontroller.
®
The ST Zio connector, which extends the ARDUINO
Uno V3 connectivity, and the ST morpho headers provide easy expansion
of the functionality of the STM32 Nucleo open development platform with a wide choice of specialized shields.
The STM32U5 Nucleo-144 board does not require any separate probe as it integrates the STLINK-V3E debugger/programmer.
The STM32U5 Nucleo-144 board comes with the STM32 comprehensive free software libraries and examples available with the
STM32CubeU5
MCU Package.

Page 17: Power Supply And Power Selection
This power switch also features a 500 mA current limitation, to protect the PC in case of an onboard short-circuit. The STM32U5 Nucleo-144 board with its shield can be powered from the CN1 STLINK-V3E USB connector, but only the STLINK-V3E circuit has the power before USB enumeration because the host PC only provides 100mA to the board at that time. -
Page 18: Figure 10. Jp6 [1-2]: 5V_Stlk Power Source
UM2861 Power supply and power selection • If the host is not able to provide the requested current, the enumeration fails. Therefore, the U2 power switch remains OFF and the MCU part including the extension board is not powered. As a consequence, the LD5 green LED remains OFF. -
Page 19: Figure 11. Jp6 [3-4]: 5V_Vin Power Source
VIN (5V_VIN) is the 7 to 12 V DC power from the CN8 ARDUINO the connector silkscreen, or from the CN11 ST morpho connector pin 24. In this case, the JP6 jumper must be on pin [3-4] to select the 5V_VIN power source. In that case, the DC power comes from the power supply through the ®... -

UM2861 Power supply and power selection ® 5V_USB_C is the DC power supply connected to the CN15 user USB Type-C connector. In this case, the JP6 jumper must be set on [7-8] to select the 5V_USB_C power source. 5V_USB_C configuration: The JP6 jumper must be set on [7-8] as shown in Figure Figure 13. -
Page 22: Figure 14. Jp6 [9-10]: 5V_Chgr Power Source
UM2861 Power supply and power selection 5V_CHGR is the DC power charger connected to the CN1 USB STLINK-V3E connector. In this case, the JP6 jumper must be set on [9-10] to select the 5V_CHGR power source. If an external USB charger powers the Nucleo board, then the debug through CN1 is not available. -
Page 23: Programing/Debugging When The Power Supply Is Not From Stlink-V3E (5V_Stlk)
UM2861 Power supply and power selection External 3V3 power supply input. In certain situations, it is interesting to use an external 3V3 (CN8 pin 7, CN11 pin 16, or JP5 pin 2) directly as power input, for instance in case the 3V3 is provided by an extension board. When Nucleo is powered by 3V3, the STLINK-V3E is not powered thus programming and debug features are unavailable. -
