General description
By default, the STM32WB09KE embedded on this Nucleo board is supplied by 3V3 but the board proposes many
possibilities to supply the module. In fact, at first, the 3V3 can come from ST-LINK USB, ARDUINO®, or ST
morpho connectors. Moreover, STM32WB09KE can be supplied by an external source (between 1.8 and 3.3 V).
Thanks to level shifters, debugging by embedded STLINK is always possible even if the supply voltage of the
target is different than 3V3 (ST-LINK supply). Figure 7 shows the power tree. Moreover, this figure also shows the
default state of the jumpers and the solder bridges.

7 to 12 V power supply
A 7 to 12 V DC power source can power NUCLEO-WB09KE. There are three accesses for this type of level:
•
•
•
Pin VIN of the ARDUINO® connector (CN5-8). It is possible to apply until +12 V on this pin or use an
ARDUINO® shield, which can deliver this type of voltage on the VIN pin.
Pin VIN of the ST morpho connector (CN3-24). It is possible to apply until +12 V on this pin like for
theARDUINO® connection.
External input (CN10). Be careful, in this case, the states of the jumpers and solder bridge are significant. A
solder bridge configuration might allow a direct supply of STM32WB09, with a high risk of destruction if
above 3.3 V. Refer to Figure 7 and Table 4.
These sources are connected to a linear low‑drop voltage regulator (U3). The output of this 5 V regulator is a
potential source of the 5V signal. For further details, refer to the next section.

External input (CN10). Be careful, in this case, the states of the jumpers and solder bridge are significant. A
solder bridge configuration might allow a direct supply of STM32WB09KE, with a high risk of destruction
if above 3.3 V. Refer to Figure 7 and Table 4.
5V_EXT from ST morpho connector (CN3-6)
R7-12 V input through the voltage regulator (U3). Refer to Section 7.1.2: 7 to 12 V power supply.
The jumper (JP1) allows selecting the 5V source. Table 4 shows the configuration to apply the selected source.
Depending on the current needed on the devices connected to the USB port, and the board itself, power
limitations can prevent the system from working as expected. The user must ensure that NUCLEO-WB09KE is
supplied with the correct power source depending on the current needed.

Current measurement
As the device has low‑power features, it can be interesting to measure the current consumed by NUCLEOWB09KE. To do this measurement easily, there are two possibilities:
1. Measure the supply current of the SoC using an ammeter in place of the jumper (JP2). Since the
STM32WB09 power consumption is usually very low, an accurate instrument in the range of a few microamps
is recommended.
All supply sources can be used except the AVDD coming from the ARDUINO® connector. Figure 8 shows the
configuration.

SW1 switch use
SW1 is a two‑position switch that selects a power source to connect to V_Target and VDD. Therefore, it
determines the supply voltage for STM32WB09.
1. Position [1-2]: It is the default position. The voltage source is the U4 LDO providing 3.3 V
DT59407V1
Figure 10. SW1 default setting
2. Position [3-2]: The power source is the voltage injected at VIN, 5V_EXT, or VEXT, depending on SB20, SB21,
SB22, and SB33 configuration. It is highly recommended never to use this configuration, as there is no
system to ensure the correct value of the voltage.

Embedded STLINK-V3EC
The chapter below gives some information about the implementation of STLINK-V3EC.
For more details on STLINK-V3EC such as LED management, drivers, and firmware, refer to the technical note
Overview of ST-LINK derivatives (TN1235).
For information about the debugging and programming features of STLINK-V3EC, refer to the user manual
STLINK-V3SET debugger/programmer for STM8 and STM32 (UM2448).
7.4.1
Description
There are two different ways to program and debug the onboard STM32 MCU:
•
•
Using the embedded STLINK-V3EC programming and debugging tool on the NUCLEO-WB09KE board
Using an external debug tool connected to the MIPI10 connector (CN17) on the MB1801 board
The STLINK-V3EC facility for debugging and flashing is integrated into the NUCLEO-WB09KE board.
Supported features in STLINK-V3EC:
•
•
•
•
•
•
•
•
5 V/500 mA power supply capability through the USB Type-C® connector (CN15)
USB 2.0 high-speed-compatible interface
JTAG and Serial Wire Debug (SWD) with Serial Wire Viewer (SWV)
Virtual COM port (VCP)
1.7 to 3.6 V application voltage
COM status LED that blinks during communication with the PC
Power status LED that gives information about STLINK-V3EC target power
Overvoltage protection with current limitation
Two tricolor LEDs (green, orange, and red) provide information about the STLINK-V3EC communication status
(LD6) and STLINK-V3EC power status (LD5).
For detailed information about the management of these LEDs, refer to the technical note Overview of ST-LINK
derivatives (TN1235).
7.4.2
Drivers
The installation of drivers is not mandatory from Windows® 10 but allocates an ST‑specific name to the ST-LINK
COM port in the system device manager.
For detailed information on the ST-LINK USB drivers, refer to the technical note Overview of ST-LINK derivatives
(TN1235).
7.4.3
STLINK-V3EC firmware upgrade
STLINK-V3EC embeds a firmware upgrade (STSW-LINK007) mechanism through the USB Type-C® port. As the
firmware might evolve during the lifetime of the STLINK-V3EC product (for example to add new functionalities, fix
bugs, and support for new microcontroller families), it is recommended to keep the STLINK-V3EC firmware
up‑to‑date before starting to use the NUCLEO-WB09KE board. The latest version of the ST-LINK firmware is
available from the www.st.com website.
For detailed information about firmware upgrades, refer to the technical note Overview of ST-LINK derivatives
(TN1235).

7.4.4
Using an external debug tool to program and debug NUCLEO-WB09KE
Before connecting any external debug tool to the STDC14 debug connector (CN17), the SWD and VCP signals
from STLINK-V3EC must be isolated. For this, fit the jumper on JP4. It disables the U9 level shifter and isolates
SWD and VCP signals from STLINK-V3EC. The configuration of the JP4 is explained in Table 5.

The STDC14 connector supports 1V8 or 3V3 for the target reference voltage. When using the external debug
connector (CN17), STLINK-V3EC can be used to supply the board through the USB Type-C® connector (CN15).
STLINK-V3EC USB connector (CN15)
The main function of this connector is the access to STLINK-V3EC embedded on NUCLEO-WB09KE for the
debugging as explained above. It allows supplying the board (refer to Section 7.1: Power supply). The connector
is a standard USB Type-C® connector.
7.4.6
Virtual COM port USART
STLINK-V3EC offers a USB Virtual COM port bridge. This feature allows access to the USART of NUCLEOWB09KE by the ST-LINK USB connector (CN15). By default, the USART interface of NUCLEO-WB09KE is
connected to the VCP1 of the STLINK-V3EC MCU (STM32F723IEK6).
An intermediate connection allows the use of this VCP differently. On the CN14 connector, both signals (Tx and
Rx) are available, and two resistors (R55 – 0 Ω and R56 – 33 Ω on MB1801) allow disconnecting the UART
coming from the SoC.

Virtual COM port LPUART1
It is possible to replace the mass storage interface with a second Virtual COM port. To do so, the SB7 and SB8
solder bridges must be ON. It is also necessary to do a firmware upgrade through STM32CubeProgrammer (refer
to the technical note Overview of ST-LINK derivatives (TN1235) at www.st.com.
7.4.8
Level shifter
NUCLEO-WB09KE has a system for supplying STM32WB09KE with a different voltage than the ST-LINK. STLINK is always supplied by 3V3 sources. By default, the STM32WB09KE is supplied by the same voltage value
as ST-LINK, but it is possible to supply the SoC with another value. It accepts voltage between 1.8 and 3.3 V trust
to a specific component (U9 level shifter). This level shifter assures the voltage conversion between ST-LINK and
the SoC. It drives SWD and UART signals connected to the VCP on ST-LINK.

The LED is OFF: the target is not powered by the ST-LINK.
The LED is orange: The requested board power budget is higher than the USB power budget. The
ST-LINK starts working normally, but there is a risk of exceeding the USB budget to supply the STLINK and the target application. Connect the board to a more powerful USB port for correct
functioning.
The LED is green: The requested board power budget is less than or equal to the USB power
budget.
The LED is red: an overcurrent is detected on the board and the target power is switched off
automatically (overcurrent protection). The cause of the overcurrent must be investigated, or the
board must be connected to a more powerful USB port.
The LED is blinking red: internal error; update the board with the most recent firmware available at
www.st.com. If the issue persists, contact STMicroelectronics support.

Operating voltage
The ARDUINO® Uno V3 connectors support 5 V, 3.3 V, and VDD for I/O compatibility.
Caution:
Do not supply 3.3 V or 5 V from the ARDUINO® shield. Supplying 3.3 V or 5 V from the ARDUINO® shield might
damage the Nucleo board.
Caution:
If STM32WB09KE is supplied using CN10 (VEXT), great care must be taken with the settings of SB22 and SW1.
If SB22 is mounted and SW1 set to [2-3], STM32WB09KE is then directly supplied by VEXT, with destructive
damages if VEXT is above 3.3 V.
Furthermore, if it is necessary to supply the Nucleo board by the ARDUINO® connector, a dedicated pin is
available. VIN allows supplying the board directly. To use this feature, refer to Section 7.1.2: 7 to 12 V power
supply.

VEXT is not connected to VIN. Through SB33, it is connected
to 5V_EXT and is possibly distributed to JP1 (position [7‑8]
through SB21) and SW1 (position [2‑3] through SB22). This is
why it is highly recommended to keep SB22 OFF and more
globally to keep the default configuration of SB20, SB21, SB22,

The preprogrammed bootloader is an application, which is stored in the internal ROM at manufacturing time by
STMicroelectronics. This application allows upgrading the flash device with a user application using a serial
communication channel (UART).
The jumper JP1 activates the bootloader by forcing PA10 high during hardware reset, otherwise, the application
residing in flash memory is launched.
Figure 17. JP1 (MB2032 board) default setting
Jumper connects 2 and 3: The application residing in flash memory is launched (default position)
Jumper connects 2 and 1: The bootloader is activated and the user can download a new application.
Note:
Note: With the BLE_p2pserver demo programmed in the NUCLEO-WB09KE, the low‑power mode is enabled to
offer the best low‑power performances. Therefore, on STM32WB09KE, the SWD lines are OFF and the tool
cannot connect with the device anymore.
To reconnect or reprogram the Nucleo board, it is necessary to enter the Bootloader mode. To do this, the JP1
jumper on the MB2032 MCU RF board must connect 2 and 1.

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.
