Introduction
The X-NUCLEO-WBA25A1 ARDUINO
®
interface board provides Bluetooth
®
LE connectivity for developer applications and can
be plugged into an STM32 Nucleo board, such as NUCLEO-U385RG-Q, using the ARDUINO
®
Uno V3 connectors.
The ARDUINO
®
interface board features the Bluetooth
®
v6.0-compliant and FCC-certified STM32WBA25CE SoC. This device
manages the complete Bluetooth
®
LE stack and protocols using its Arm
®
Cortex
®
-M33 core and programmable flash memory.
X-NUCLEO-WBA25A1 uses the universal asynchronous receiver transmitter (UART) interface to communicate with the STM32
Nucleo board. It supports operations with or without hardware flow control. A full-duplex serial peripheral interface (SPI) with an
interrupt line is also available. The firmware loaded on the module determines the host interface. To change the interface,
update the firmware without modifying the hardware.

5 Safety recommendations
5.1 Targeted audience
This product targets users with at least basic electronics or embedded software development knowledge like
engineers, technicians, or students.
This board is not a toy and is not suited for use by children.
5.2
Handling the board
This product contains a bare printed circuit board and like all products of this type, the user must be careful about
the following points:
• The connection pins on the board might be sharp. Be careful when handling the board to avoid injury.
• This board contains static sensitive devices. To avoid damaging it, handle the board in an ESD‑proof
environment.
• While powered, do not touch the electric connections on the board with your fingers or anything conductive.
The board operates at a voltage level that is not dangerous, but components might be damaged when
shorted.
• Do not put any liquid on the board and avoid operating it close to water or at a high humidity level.
• Do not operate the board if it is dirty or dusty.
• The pins of the board are exposed and must not come into contact with a metal surface, as this can
produce a short circuit and damage the board.
5.3 Delivery recommendations
Before the first use, inspect the board for any damage that may have occurred during shipment. Ensure that all
socketed components are securely fixed in their sockets and that nothing is loose in the plastic bag.

8.5 UART/SPI connection options
UART interface options
X-NUCLEO-WBA25A1 interfaces with the microcontroller of the STM32 Nucleo board using UART (default) with
and without hardware flow control.
Several UART connection options between the STM32 Nucleo board and the X-NUCLEO-WBA25A1 expansion
board are available. The options depend on the Nucleo board used or if a signal conflict occurs when using other
expansion boards. To determine which UART signals to connect, first review the STM32 Nucleo schematics.
SPI interface option
X-NUCLEO-WBA25A1 can also interface with the STM32 Nucleo microcontroller using full duplex SPI with an
interrupt line. For
SPI connection details, refer to Table 4. X-NUCLEO-WBA25A1 and NUCLEO-U385RG-Q

10 X-NUCLEO-WBA25A1 product information
10.1 Product marking
The product and each board composing the product are identified with one or several stickers. The stickers,
located on the top or bottom side of each PCB, provide product information:
• Main board featuring the target device: product order code, product identification, serial number, and board reference
with revision.
Single-sticker example:
DT73589V1
Product order code
Product identification
syywwxxxxx
MBxxxx-Variant-yzz
Dual-sticker example:
Product order code
Product identification
and
MBxxxx-Variant-yzz
syywwxxxxx
• Other boards if any: board reference with revision and serial number.
Examples:
DT76507V1
syywwxxxxx
MBxxxx-Variant-yzz
or
MBxxxx-Variant-yzz
syywwxxxxx
or
DT76508V1
or
On the main board sticker, the first line provides the product order code, and the second line the product
identification.
On all board stickers, the line formatted as “MBxxxx-Variant-yzz” shows the board reference “MBxxxx”, the
mounting variant “Variant” when several exist (optional), the PCB revision “y”, and the assembly revision “zz”, for
example B01. The other line shows the board serial number used for traceability.
Products and parts labeled as “ES” or “E” are not yet qualified or feature devices that are not yet qualified.
STMicroelectronics disclaims any responsibility for consequences arising from their use. Under no circumstances
will STMicroelectronics be liable for the customer's use of these engineering samples. Before deciding to use
these engineering samples for qualification activities, contact STMicroelectronics' quality department.
“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 ordering part number of the evaluation tool 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.
