Introduction
The STM32 Nucleo-64-P boards (NUCLEO-L412RB-P, NUCLEO-L433RC-P and
NUCLEO-L452RE-P) provide an affordable and flexible way for users to try out new
concepts and build prototypes with the STM32 microcontroller and the external SMPS
(switched mode power supply), which provides various combinations of performance, power
consumption and features.

expanding the functionality of the Nucleo open development platform with a wide choice of
specialized shields.
The STM32 Nucleo-64-P boards do not require any separate probe, as they integrate the
ST-LINK/V2-1 debugger/programmer. The STM32 Nucleo-64-P boards come with the
comprehensive free STM32 software libraries and examples that are available with the
STM32Cube package.

ST-LINK/V2-1 firmware upgrade The ST-LINK/V2-1 embeds a firmware upgrade mechanism for in-situ upgrade through the USB port. As the firmware may evolve during the lifetime of the ST-LINK/V2-1 product (for example new functionalities, bug fixes, support for new microcontroller families), it is recommended to keep the ST-LINK/V2-1 firmware up to date before starting to use an STM32 Nucleo-64-P board. -

Page 18: Power Supply And Power Selection
5V_ST_LINK is a DC power with limitation from ST-LINK USB connector (USB type Micro-B connector of ST-LINK/V2-1). In this case JP5 jumper should be on pins 1 and 2 to select 5V_STL power source on silkscreen of JP5. This is the default setting. If the USB enumeration succeeds, the 5V_ST_LINK power is enabled, by asserting the PWR_ENn signal (from STM32F103CBT6). -

JP5 [5-6] ON E5V: CN5 pin 6 5V_USB_CHARGER is the DC power charger connected to USB ST-LINK (CN1). To select the 5V_USB_CHARGER power source on silkscreen of JP5, the jumper of JP5 should be on pins 7 and 8. In this case, if the STM32 Nucleo-64-P board is powered by an external USB charger the debug is not available. -

Solder bridge SB9 can be used to bypass the USB power protection ST890. (This is not an ST recommended setting). SB9 can be set in case the board is powered by the USB of the PC and maximum current consumption on 5V_STLINK does not exceed 100 mA (including extension board or Arduino shield power consumption). -
