Bluetooth
Low Energy and 802.15.4 Nucleo pack
based on STM32WB Series microcontrollers
Introduction
The Nucleo pack (P-NUCLEO-WB55) with a Nucleo-68 board and a USB dongle provides
an affordable and flexible way for users to try out new concepts and build prototypes using
STM32WB microcontrollers with a 2.4 GHz radio interface.
This circuit block provides various combinations of performance, power consumption and
®
features. A 2.4 GHz RF transceiver supporting Bluetooth
specification v5.0 and IEEE
802.15.4-2011 PHY and MAC is supported.
Arduino™ Uno V3 connectivity and ST morpho headers allow the user to easily expand the
functionality of the Nucleo open development platform with a wide choice of specialized
shields.
®
The boards are based on a multiprotocol wireless 32-bit microcontroller, based on an Arm
®
®
Cortex
-M4 with FPU, featuring Bluetooth
Low Energy and 802.15.4 radio solution.
The STM32 Nucleo-68 board does not require any separate probe, as it integrates the
ST-LINK/V2-1 debugger/programmer. The board comes with the comprehensive free
STM32 software libraries and examples available with the STM32Cube package.
The USB dongle can be programmed through USB BootLoad or USB DFU. It is also
possible to debug/program it with an external STLink V2 (not delivered), using the SWD
interface.

Page 27: Power Supply And Selection
This power switch also features a current limitation to protect the PC in case of currents exceeding 750 mA. The Nucleo board and the shield on it can be powered from ST-LINK USB connector CN15, but only ST-LINK circuit has the power before USB enumeration, because the host PC only provides 100 mA to the board at that time. -
Page 28: Figure 18. Jp1[7-8]: 5V_Stl Power Source
Hardware layout and configuration UM2435 and its shield can use up to 500 mA. If the host is unable to provide the requested current, the enumeration fails. Therefore the power switch STMPS2141STR remains OFF and the MCU is not powered. As a consequence LED5 remains turned OFF. In this case it is mandatory to use an external power supply. -

Page 31: External Power Supply Output
It is possible to be also in LDO mode by changing the firmware, SB31 needs to be closed. Programing/debugging when the power supply is not from USB ST-LINK (5V_ST_link) VIN or 5V_EXT can be used as external power supply if the current consumption of Nucleo and extensions boards exceeds the allowed current on USB. -
Page 32: Osc Clock Sources
In some cases it can be interesting to use the 3V3 (CN6 pin 4 or CN7 pin 16) directly as power input, for instance when the 3.3 V is provided by an extension board. When Nucleo is powered by 3V3, the ST-LINK is not powered, thus programming and debug features are unavailable. -
