NUCLEO-WB55RG NUCLEO-WB15CC Data brief STM32WB Nucleo-64 boards Features Common features STM32WB55RG (1-Mbyte Flash memory, 256-Kbyte SRAM, in VFQFPN68 package) or STM32WB15CC (320-Kbyte Flash memory, 48-Kbyte SRAM, in VFQFPN48 package) ultralowpower wireless microcontroller featuring: Dual-core 32 bit (Arm Cortex -M4 and dedicated M0+ CPU for real- time radio layer) 2.4 GHz RF transceiver supporting Bluetooth specification v5.2 Three user LEDs One reset and three user push-buttons Board connectors: NUCLEO-WB55RG example. Boards with different references show different ARDUINO Uno V3 expansion connector layouts. Picture is not contractual. ST morpho extension pin headers for full access to all STM32WB I/Os Integrated PCB antenna and SMA connector footprint Flexible power-supply options: ST-LINK, USB V , or external sources BUS On-board footprint to mount a CR2032 battery socket On-board ST-LINK/V2-1 debugger/programmer with USB re-enumeration capability: mass storage, Virtual COM port, and debug port Comprehensive free software libraries and examples available with the STM32CubeWB MCU Package Support of a wide choice of Integrated Development Environments (IDEs) including IAR Embedded Workbench , MDK-ARM, STM32CubeIDE, and Product status link Mbed Studio NUCLEO-WB55RG Board-specific features (STM32WB55RG only) USB user with Micro-B connector NUCLEO-WB15CC 2.4 GHz RF transceiver supporting IEEE 802.15.4-2011 PHY and MAC with Zigbee , Thread , and proprietary protocols Description The NUCLEO-WB55RG and NUCLEO-WB15CC STM32WB Nucleo-64 boards are Bluetooth Low Energy (BLE) wireless and ultra-low-power devices embedding a powerful and ultra-low-power radio compliant with the Bluetooth Low Energy (BLE) SIG specification v5.2. NUCLEO-WB55RG also offers a radio compliant with IEEE 802.15.4-2011 standard and allows the simple and quick evaluation of STM32WB55xx and STM32WB35xx devices. The ARDUINO Uno V3 connectivity support and the ST morpho headers provide an easy means of expanding the functionality of the STM32WB Nucleo open development platform with a wide choice of specialized shields.

For a detailed description of each board, refer to its user manual on the product web page. Additional information is available from the datasheet and reference manual of the target STM32. Table 1. List of available products Board User Order code Target STM32 Differentiating feature reference manual USB user with Micro-B connector Radio compliant with NUCLEO-WB55RG MB1355 UM2819 STM32WB55RGV6U IEEE 802.15.4-2011 standard supporting Zigbee , Thread , and proprietary protocols NUCLEO-WB15CC MB1641 UM2823 STM32WB15CCU6U - 1.1 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 identification line has the following format: MBxxxx-Variant-yzz, where MBxxxx is the board reference, Variant (optional) identifies the mounting variant when several exist, is the PCB revision andz is the assembly revision, for example B01. The second identification line is 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. These boards feature a specific STM32 device version, which allows the operation of any bundled commercial stack/library available. This STM32 device shows a 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. DB4388 - Rev 1 page 2/6
