Page 14 WB07CC. To do this measurement easily, there are two possibilities: 1. Measure the supply current of the SoC using an ammeter in place of the jumper (JP2). Since the STM32WB07 power consumption is usually very low, an accurate instrument in the range of a few microamps is recommended.
Page 15 SW1 is a two‑position switch that selects a power source to connect to V_Target and VDD. Therefore, it determines the supply voltage for STM32WB07. 1. Position [1-2]: It is the default position. The voltage source is the U4 LDO providing 3.3 V Figure 10.
Page 16 • On-board oscillator (default): X2 crystal connected to PB12 and PB13. Refer to the application note Guidelines for oscillator design on STM8AF/AL/S and STM32 MCUs/MPUs (AN2867). ST recommends using NX2012SA-32.768KHZ-EXS00A-MU00389 (32.768 kHz, 7 pF load capacitance, 20 ppm) from NDK.

Page 18 The NUCLEO-WB07CC board also offers the flexibility to connect the LPUART or the USART interface to ® STLINK-V3EC, or to the ST morpho and ARDUINO Uno V3 connectors. By default, the USART interface of NUCLEO-WB07CC is connected to the VCP1 of the STLINK-V3EC MCU (STM32F723IEK6).
Page 19 NUCLEO-WB07CC has a system for supplying STM32WB07CC with a different voltage than ST-LINK. ST-LINK is always supplied by 3V3 sources. By default, STM32WB07CC 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 (U6, U9, and U15 level shifters).
Page 20 The LED is orange: The requested board power budget is higher than the USB power budget. ST- LINK starts working normally, but there is a risk of exceeding the USB budget to supply ST-LINK and the target application. Connect the board to a more powerful USB port for correct functioning.
Page 21 The LED is blinking red: the first USB enumeration with the PC is taking place. If an ST-LINK upgrade application is running, the firmware is being programmed. – The LED is red: ST-LINK is in the idle state (the USB enumeration with the PC is finished and ST- LINK is waiting for an application to connect). –...

Page 23 Note that PA0 is also connected to the ARDUINO and ST morpho connectors as a GPIO, depending on the use case that can generate conflict with B1. In this case, it is possible to remove the connection of B1 (SB2 OFF on the MB1801 mezzanine board).
Page 24 UM3344 Hardware layout and configuration ® ARDUINO connectors 7.8.1 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 Nucleo kits to offer flexibility in small form factor applications.
