Nano connectivity support makes it easy to expand the functionality of the Nucleo-32 open development platform with a wide choice of specialized shields. The STM32 Nucleo-32 boards do not require any separate probe as they integrate the ST- LINK/V2-1 debugger/programmer and come with the STM32 comprehensive software HAL library, together with various packaged software examples.
• Flexible board power supply options: – ST-LINK USB V – External sources • 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 STM32Cube MCU Package •...

UM1956 Safety recommendations Safety recommendations Targeted audience This product targets users with at least basic electronics or embedded software development knowledge such as engineers, technicians, or students. This board is not a toy and is not suited for use by children. 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:...
• To correctly identify all device interfaces from the host PC before connecting the board, install the Nucleo USB driver, available at the www.st.com/stm32nucleo webpage. • To power the board, connect the STM32 Nucleo-32 board to a PC through the USB ®...
Hardware layout and configuration The STM32 Nucleo-32 board is based on a 32-pin STM32 microcontroller in an LQFP or UFQFPN package. Figure 2 illustrates the connections between the STM32 and its peripherals (ST-LINK/V2-1, ® push-button, LED, and ARDUINO Nano connectors).
Activating the readout protection on the STM32 target, prevents the target application from running afterwards. The target readout protection must be kept disabled on ST- LINK/V2-1 boards. The embedded ST-LINK/V2-1 is directly connected to the SWD port of the target STM32. 7.3.1 Drivers ®...
ST-LINK/V2-1 firmware upgrade The ST-LINK/V2-1 embeds a firmware upgrade mechanism for in-place upgrade through the USB port. The firmware might evolve during the lifetime of the ST-LINK/V2-1 product (for example new functionalities added, bug fixes, and support for new microcontroller families).
62368-1:2014+A11:2017 or the standard that replaces it. It must also be a safety extralow voltage (SELV) with limited power capability. If the power supply is +3V3, the ST-LINK is not powered and cannot be used. 7.4.1 Power supply input from USB connector The STM32 Nucleo-32 board and shield board can be powered by the ST-LINK USB connector CN1.
SB9 must be off. VIN or +5 V power supply When powered from VIN or +5 V, it is still possible to use ST-LINK for communication for programming or debugging only, but it is mandatory to power the board first, using VIN or +5 V, then connect the USB cable to the PC.
Using the +3V3 (CN4 pin 14) directly as a power input can be interesting, for instance, if 3.3 V is provided by a shield board. In this case, ST-LINK is not powered, thus programming and debugging features are unavailable. When the board is powered by +3V3 (CN4 pin 14), the solder bridge SB14 and SB9 (NRST) must be off.
1. In applications where VCP is used for communication at a speed higher than 9600 bauds, it might be needed to use this solder bridge configuration, to use an 8 MHz clock (MCO from ST-LINK) and get a better precise frequency.
Hardware layout and configuration USART virtual communication Thanks to SB2 and SB3, the USART interface of STM32 available on PA2 (TX) and PA15 (Rx), can be connected to ST-LINK/V2-1. When USART is not used, it is possible to use ® PA2 as ARDUINO Nano A7.
