Power supply and power selection
Six different sources can provide the power supply to the board:
·
A host PC connected to CN1 through a USB cable (default configuration)
·
An external 7 to 12 V power supply connected to CN6 pin 8 or CN7 pin 24 (VIN)
·
An external 5 V power supply connected to CN7 pin 6 (E5V)
·
An external 5 V USB charger (VBUS_STLK) connected to CN1
·
A host PC connected to CN3 through a USB cable
·
An external 3.3 V power supply (3V3) connected to CN6 pin 4 or CN7 pin 16
Either the host PC through the USB cable, or an external source VIN (7 to 12 V), E5V (5 V), or +3.3 V power supply pins on CN6 or CN7, provides the power supply. In case VIN, E5V, or +3.3 V is used to power the STM32H5 Nucleo-64 board. This power source must comply with the EN-60950-1: 2006+A11/2009 standard and must be SELV (safety extra low voltage) with limited power capability.
In case the power supply is +3.3 V, STLINK-V3EC is not powered and cannot be used.
Power supply input from STLINK-V3EC USB connector: 5V_STLK (default configuration)
The STM32H5 Nucleo-64 board and shield can be powered from STLINK-V3EC connector CN1 (5 V/500 mA). To select the 5V_STLK power source, JP5 must be fitted on [1-2] `5V_STLK' (refer to Figure 10). This is the default configuration.
Figure 10. Power supply input from STLINK-V3EC USB connector with PC (5 V, 500 mA maximum)
PC 5V
DT59079V2
5V 3V3
If the USB enumeration succeeds, the ST-LINK power is enabled, by asserting the T_PWR_EN signal from STLINK-V3EC. This pin is connected to a power switch (U4), which powers the board. The power switch also features a current limitation to protect the PC in case of a short circuit onboard. If an overcurrent (more than 500 mA) happens onboard, the POWER status LED (LD7) is lit in red color.
The STLINK-V3EC USB connector (CN1) can power the STM32H5 Nucleo-64 board with its shield.
·
If the Host can provide the required power, the power switch (U4) and the green LED (LD3) are turned ON.
Thus, the STM32H5 Nucleo-64 board and its shield can consume up to 500 mA current, but not more.
·
If the Host is not able to provide the requested current, the enumeration fails. Therefore, the power switch
(U4) remains OFF and the MCU part including the extension board is not powered. As a consequence, the
green LED (LD3) remains turned OFF. In this case, it is mandatory to use an external power supply.
Warning:
In case the maximum current consumption of the STM32H5 Nucleo-64 board and its shield boards exceed 500 mA, it is mandatory to power the STM32H5 Nucleo-64 board, using an external power supply connected to E5V, VIN, or +3.3 V.

External power supply input from VIN (7 to 12 V, 800 mA maximum)
When the STM32H5 Nucleo-64 board is power supplied by VIN, the JP5 jumper must be fitted on [3-4] '5V_VIN' (refer to Figure 11 and Table 7. The STM32H5 Nucleo-64 board and its shield boards can be powered in three different ways from an external power supply, depending on the used voltage. The three power sources are summarized in Table 7.

Programming/debugging when the power supply is not from
STLINK-V3EC (STLK)
When powered by VIN, E5V, or USB user, it is still possible to use STLINK-V3EC for VCP, programming, or debugging.
In this case, the following power sequence procedure must be respected:
1. Set the JP5 jumper according to the selected 5 V power source.
2. Connect the external power source according to JP5.
3. Power on the external power supply.
4. Check that the 5 V green LED (LD3) is turned ON.
5. Connect the PC to the USB ST-LINK connector (CN1).
If this sequence is not respected, the VBUS from STLINK-V3EC might power the board first, and the following risks might be encountered:
·
If the board needs more than 500 mA current, the PC might be damaged or the current limited by the PC.
Therefore, the board is not powered correctly.
·
500 mA is requested at enumeration. So, there is a risk that the request is rejected and the enumeration
does not succeed, as the PC cannot provide such a current. Consequently, the board is not power supplied
and the 5 V green LED (LD3) remains OFF.

LEDs
STLINK-V3EC COM (LD1) and STLINK-V3EC POWER STATUS (LD7) LEDs
Two tricolor (green, orange, and red) LEDs provide information about the STLINK-V3EC communication status (LD1) and STLINK-V3EC power status (LD7). For detailed information about these two LEDs, refer to the technical note Overview of ST-LINK derivatives (TN1235).
User LED (LD2) This green LED is a user LED connected to STM32H5 I/O PA5 (SB6 ON) corresponding to the ARDUINO® D13. To light LD2, a high logic state '1' must be written into the corresponding GPIO PA5. A transistor is used to drive the LD2. The user can modify and program the function of the user LED (LD2) to give another status signal that might be relevant to the board. LD2 consumption does not impact the VDD STM32H5 power measurement, since LD2 is isolated from it.
PWR LED (LD3)
The green LED (LD3) is used as a board poweron indicator and indicates that the STM32H5 Nucleo-64 is powered by a 5 V power source and +5V is available on CN6 pin 5 and CN7 pin 18.
USB power fault (OC, overcurrent) LED (LD4)
LD4 indicates that the board power consumption via the USB ST-LINK exceeds 500 mA. Consequently, the user must power the board using an external power supply.
USB power fault (OC, overcurrent) LED (LD5)
The red LED (LD5) indicates that the power consumption via the USB user exceeds 500 mA when the STM32H5 Nucleo-64 board works as a Host.
USB Type-C® LED (LD6)
The green LED (LD6) indicates the presence of VBUSC (5 V) on the USB user connector (CN3). Refer to the Power supply input from the USB user connector for more details.

Board functions
Push-buttons
Two buttons are available on the STM32H5 Nucleo-64 board.
Blue user button (B1)
The user button is connected to the PC13 I/O by default (tamper support: SB16 ON and SB21 OFF). The user button can also be connected to PA0 (wake-up support: SB21 ON and SB16 OFF) of the STM32H5 series microcontroller. When the button is pressed, the logic state is HIGH, otherwise, the logic state is LOW.
Black reset button (B2)
This push-button is connected to NRST and is used to reset the STM32H5 series microcontroller. When the button is pressed, the logic state is LOW, otherwise, the logic state is HIGH.
Current consumption measurement (IDD)
The JP2 jumper, labeled IDD, is used to measure the STM32H5 microcontroller consumption by removing the jumper and connecting an ammeter:
·
JP2 must be ON when STM32H5 is powered with VDD (default).
·
If JP2 is OFF, an ammeter must be connected to measure the STM32H5 current. If there is no ammeter,
the STM32H5 is not powered.
Virtual COM port (VCP): USART1/USART2/USART3
Depending on the STM32H5 Nucleo-64 board, it is possible to choose between several USART interfaces (USART1, USART2, or USART3) to connect to STLINK-V3EC.
The selection between USART1, USART2, and USART3 is done by setting the related solder bridges as detailed in Table 13.

STM32H5 Nucleo-64 product information
Product marking
The stickers located on the top or bottom side of all PCBs provide product information:
·
First sticker: product order code and product identification, generally placed on the main board featuring
the target device.
Example:
Product order code Product identification
·
Second sticker: board reference with revision and serial number, available on each PCB.
Example:
MBxxxx-Variant-yzz syywwxxxxx
On the first sticker, the first line provides the product order code, and the second line the product identification. On the second sticker, the first line has the following format: "MBxxxx-Variant-yzz", where "MBxxxx" is the board reference, "Variant" (optional) identifies the mounting variant when several exist, "y" is the PCB revision, and "zz" is the assembly revision, for example B01. The second line shows the board serial number used for traceability. Parts marked as "ES" or "E" are not yet qualified and therefore not approved for use in production. ST is not responsible for any consequences resulting from such use. In no event will ST be liable for the customer using any of these engineering samples in production. ST's Quality department must be contacted prior to any decision to use these engineering samples to run a qualification activity. "ES" or "E" marking examples of location:
·
On the targeted STM32 that is soldered on the board (for an illustration of STM32 marking, refer to the
STM32 datasheet Package information paragraph at the www.st.com website).
·
Next to the evaluation tool ordering part number that is stuck, or silk-screen printed on the board.
Some boards feature a specific STM32 device version, which allows the operation of any bundled commercial stack/library available. This STM32 device shows a "U" marking option at the end of the standard part number and is not available for sales.
To use the same commercial stack in their applications, the developers might need to purchase a part number specific to this stack/library. The price of those part numbers includes the stack/library royalties.
