1 Description

The B-U585I-IOT02A Discovery kit provides a complete demonstration and development platform for the

STM32U585AI microcontroller, featuring an Arm® Cortex®‑M33 core with Arm® TrustZone® and Armv8-M

mainline security extension, 2 Mbytes of Flash memory and 786 Kbytes of SRAM, as well as smart peripheral
resources.

This Discovery kit enables a wide diversity of applications by exploiting low-power communication, multiway
sensing and direct connection to cloud servers.

It includes Wi‑Fi® and Bluetooth® modules, as well as microphones, temperature and humidity, magnetometer,
accelerometer and gyroscope, pressure, time-of-flight and gesture-detection sensors.

The support for ARDUINO® Uno V3, STMod+ and Pmod™ connectivity provides unlimited expansion capabilities
with a large choice of specialized add-on boards.

For even more user-friendliness, the on-board STLINK-V3E debugger provides out-of-the-box loading and
debugging capabilities, as well as USB Virtual COM port bridge.

The B-U585I-IOT02A Discovery kit leverages the STM32U5 Series key assets to enable prototyping for a variety
of wearable or sensor applications in fitness, metering, industrial or medical, with state-of-the-art energy efficiency
and higher security.

2.1 Product marking

The stickers located on the top or bottom side of the PCB provide product information:

• Product order code and product identification for the first sticker

• Board reference with revision, and serial number for the second sticker

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.

Evaluation tools marked as “ES” or “E” are not yet qualified and therefore not ready to be used as reference
design or in production. Any consequences deriving from such usage will not be at ST charge. In no event, ST will
be liable for any customer usage of these engineering sample tools as reference designs or in production.

“E” or “ES” 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.

In order to use the same commercial stack in his application, a developer may need to purchase a part number
specific to this stack/library. The price of those part numbers includes the stack/library royalties.
