STM32 Nucleo-64 boards (MB1360)
Introduction
The STM32 Nucleo-64 boards, based on the MB1360 reference board (NUCLEO-G070RB,
NUCLEO-G071RB, and NUCLEO-G0B1RE order codes) provide an affordable and flexible
way for users to try out new concepts and build prototypes with the STM32 microcontroller,
which provide various combinations of performance, power consumption, and features.
®
ARDUINO
Uno V3 connectivity and ST morpho headers provide easy means of expanding
the functionality of the Nucleo open development platform with a wide choice of specialized
shields.
The STM32 Nucleo-64 boards do not require any separate probe, as they integrate the
ST-LINK/V2-1 debugger/programmer. The STM32 Nucleo-64 boards come with the
comprehensive free STM32 software libraries and examples that are available with the
STM32CubeG0 MCU Package.

Page 15: Drivers
The ST-LINK/V2-1 embeds a firmware upgrade mechanism for the 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 board. -

Page 17: Power Supply And Power Selection
The STM32 Nucleo-64 board is designed to be powered by several DC power supplies. It is possible to supply the STM32 Nucleo-64 board with any of the following sources: • 5V_USB_STLK from the ST-LINK USB connector ® • VIN (7 V - 12 V) from ARDUINO connector or ST morpho connector •... -
Page 18: Table 7. Power Supply Capabilities
5V_ST_LINK is a DC power with limitations from the ST-LINK USB connector (USB type Micro-B connector of ST-LINK/V2-1). In this case, the JP2 jumper must be on pins 1 and 2 to select the STLK power source on the JP2 silkscreen. This is the default setting. If the USB enumeration succeeds, the STLK power is enabled, by asserting the PWR_ENn signal (from STM32F103CBT6). -
Page 19: Figure 9. Stlk Power Source
VIN is the 7 V to 12 V DC power from CN6 pin 8 named VIN on ARDUINO connector silkscreen or from pin 24 of CN7 ST morpho connector. In this case, the JP2 jumper must be on pins 3 and 4 to select the VIN power source on the JP2 silkscreen. In that case, the DC ®... -
Page 20: Figure 10. Jp2 [3-4]: Stlk Power Source
CN6 PIN8 MSv48504V1 E5V is the DC power coming from external (5V DC power from pin 6 of the CN7 ST morpho connector). In this case, the JP2 jumper must be on pins 5 and 6 to select the E5V power source on the JP2 silkscreen. -
Page 21: Figure 11. Jp2 [5-6]: Stlk Power Source
E5V: CN7 PIN6 MSv48505V1 5V_USB_CHARGER is the DC power charger connected to USB ST-LINK (CN2). To select the CHG power source on the JP2 silkscreen, the JP2 jumper must be on pins 7 and 8. In this case, if the STM32 Nucleo-64 board is powered by an external USB charger the debug is not available. -
Page 22: External Power Supply Output
Nucleo-64 board and the connected shield must be less than 500 mA. Programming/debugging when the power supply is not from ST-LINK VIN or E5V is usable as an external power supply in case the current consumption of the STM32 Nucleo-64 board and its extension boards exceed the allowed current on the USB. -
