Power supply
7.1.1
General description
By default, the STM32WBA52CG embedded on this Nucleo board is supplied by 3V3 but the board proposes a lot
of possibilities to supply the module. In fact, at first, the 3V3 can come from ST-LINK USB, ARDUINO®, or ST
morpho connectors. Moreover, STM32WBA52CG 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-WBA52CG. 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 the
ARDUINO® connection
External input (CN10). Be careful, in this case, the states of the jumpers and solder bridge are very
important. Verify these states in Table 4.
These sources are connected to a linear low‑drop voltage regulator (U2). The output of this 5 V regulator is a
potential source of the 5V signal. For further details, refer to the next section.

5 V power supply
A 5 V DC power source can power NUCLEO-WBA52CG. The 5 V can come from several connectors:
•
•
•
External input (CN10). Be careful, in this case, the states of the jumpers and solder bridge are very
important. Refer to Table 4.
5V_EXT from ST morpho connector (CN5-6)
7-12 V input through the voltage regulator (U2). 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-WBA52CG is
supplied with the correct power source depending on the current needed.

When 5V_USB_STLINK is used, JP1 is set to [1-2]. The sequence is specific. In the beginning, only STLINKV3MODS is supplied. If the USB enumeration succeeds, the 5V_USB_STLINK power is enabled by asserting the
PWR_EN signal from STLINK-V3MODS. This pin is connected to a power switch (TPS2041C) which supplies the
rest of the board. This power switch also features a current limitation to protect the PC in case of currents
exceeding 300 mA.

Current measurement
As the device has low‑power features, it can be interesting to measure the current consumed by NUCLEOWBA52CG. To do this measurement easily, there are two possibilities:
1. Measure the supply current of the SoC using an amperemeter in place of the jumper (JP2). In this case, all
supply sources can be used except the AVDD coming from the ARDUINO® connector. Figure 8 shows the
configuration.

www.st.com. For Windows 10®, it is not necessary to install the driver. ST-LINK is automatically identified.
In case the NUCLEO-WBA52CG board is connected to the PC before the driver is installed, some board
interfaces might be declared as Unknown in the PC device manager. In this case, the user must install the
dedicated driver files and update the driver of the connected device from the device manager, as shown in
Figure 10. USB composite device.
Note:
It is preferable to use the USB Composite Device to handle a full recovery.

Virtual COM port USART1
STLINK-V3 offers a USB Virtual COM port bridge. This feature allows access to the USART1 of NUCLEOWBA52CG by the USB_STLNK connector. By default, this USART1 interface of NUCLEO-WBA52CG is
connected to the VCP1 of the STLINK-V3 MCU (STM32F723IE).
An intermediate connection allows the use of this VCP differently. On the CN14 connector, both signals (Tx and
Rx) are available, and two solder bridges allow disconnecting the UART coming from the SoC.

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.
7.4.6
Level shifter
NUCLEO-WBA52CG has a system for supplying STM32WBA52CG with a different voltage than the ST-LINK. The
ST-LINK is always supplied by 3V3 sources. By default, the STM32WBA52CG 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 (level shifter). This level shifter assures the voltage conversion between STLINK and the SoC. It drives SWD and UART signals connected to the VCP on the ST-LINK.

ARDUINO® connectors
Description
On the bottom side of the board, there is an ARDUINO® Uno V3 extension socket. It is built around four standard
connectors (CN5, CN6, CN7, and CN8). Most shields designed for ARDUINO® can fit with the Discovery kits to
offer flexibility in small form factor applications.

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.
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.
7.8.3
ARDUINO® interface and pinout
Figure 15 shows the position of the ARDUINO® shield when it is plugged into NUCLEO-WBA52CG with the
pinout. The pinout shown in Figure 15 corresponds to standard ARDUINO® naming. To see the correspondence
with the STM32, refer to Table 8.

NUCLEO-WBA52CG 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.
