STM32U5 Nucleo-144 board (MB1549)
Introduction
The STM32U5 Nucleo-144 board based on the MB1549 reference board (order codes
NUCLEO-U575ZI-Q
and
NUCLEO-
U5A5ZJ-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.

-included Zio connector (CN8) or ST morpho connector (CN11) If VIN, 5V_EXT, or 3V3 is used to power the STM32U5 Nucleo-144 board, this power source must comply with the standard EN‑60950‑1: 2006+A11/2009 and must be safety extra‑low voltage (SELV) with limited power capability. -
Page 17: Figure 9. Jp6 [1-2]: 5V_Stlk Power Source
The STM32U5 Nucleo-144 board and its shield can be powered from the STLINK-V3E USB connector (CN1), but only the STLINK-V3E circuit is powered before USB enumeration because the host PC only provides 100 mA to the board at that time. During the USB enumeration, the STM32U5 Nucleo-144 board requests 500 mA power to the host PC. -

VIN (5V_VIN) is the 7 to 12 V DC power source from the ARDUINO included Zio connector (CN8) pin 15 (VIN), or from the ST morpho connector (CN11) pin 24. The 5V jumper selection (JP6) must be on pin [3-4] to select ®... -

Page 21: Figure 13. Jp6 [9-10]: 5V_Chgr Power Source
5V_CHGR power source, the 5V jumper selection (JP6) must be between pins [9-10]. If an external USB charger powers the STM32U5 Nucleo-144 board, then the debugging feature through (CN1) is not available. If a host computer is connected instead of the charger, the current limitation is no more effective. In this case, the host computer can be damaged, and it is recommended to select 5V_STLK mode. -
Page 22: Programing/Debugging When The Power Supply Is Not From Stlink-V3E (5V_Stlk)
In case the current consumption of the Nucleo-144 and the expansion boards exceeds the allowed current on the ST-LINK USB connector, the external power 5V_VIN, 5V_EXT, or 5V_USB_C can be used. In such a case, it is still possible to use the embedded ST-LINK for VCP programming and debugging. -
