STM32 Nucleo-64 boards with STM32G07xRB MCUs
Introduction
The STM32 Nucleo-64 boards (NUCLEO-G070RB and NUCLEO-G071RB) 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 it integrates 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
STM32Cube package.

Page 13: Drivers
In case the STM32 Nucleo-64-P board is connected to the PC before installing the driver, the PC device manager may report some Nucleo interfaces as ‘Unknown’. To recover from this situation, after installing the dedicated driver, the association of ‘Unknown’ USB devices found on the STM32 Nucleo-64-P board to this dedicated driver, must be updated in the device manager manually. -

Page 15: Power Supply And Power Selection
DC power supply. It is possible to supply the STM32 NUCLEO-G070RB or NUCLEO-G071RB board with any of the following sources: • 5V_USB_STLK from ST-LINK USB connector • VIN (7 V - 12 V) from Arduino connector or ST morpho connector • E5V from ST morpho connector • 5V_USB_CHG from ST-LINK USB •... -
Page 16: Table 7. Power Supply Capabilities
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 JP2 jumper must be on pins 1 and 2 to select STLK power source on silkscreen of JP2. This is the default setting. If the USB enumeration succeeds, the STLK power is enabled, by asserting the PWR_ENn signal (from STM32F103CBT6). -
Page 17: Figure 9. Stlk Power Source
VIN is the 7 V to 12 V DC power from Arduino CN6 pin 8 named VIN on Arduino connector silkscreen or from ST morpho connector CN7 pin 24. In this case JP2 jumper must be on pins 3 and 4 to select VIN power source on silkscreen of JP2. In that case the DC power comes from the power supply through the Arduino Uno V3 battery shield (compatible with Adafruit PowerBoost 500 shield). -
Page 18: Figure 10. Jp2 [3-4]: Stlk Power Source
Figure 10. JP2 [3-4]: STLK power source E5V is the DC power coming from external (5V DC power from ST morpho connector CN7 pin 6). In this case JP2 jumper must be on pins 5 and 6 to select E5V power source on silkscreen of JP2. -
Page 19: Figure 11. Jp2 [5-6]: Stlk Power Source
Figure 11. JP2 [5-6]: STLK power source 5V_USB_CHARGER is the DC power charger connected to USB ST-LINK (CN2). To select the CHG power source on silkscreen of JP2, the jumper of JP2 must be on pins 7 and 8. In this case, if the STM32 NUCLEO-G070RB or NUCLEO-G071RB board is powered by an external USB charger the debug is not available. -
Page 20: External Power Supply Output
NUCLEO-G070RB or NUCLEO-G071RB 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-G070RB or NUCLEO-G071RB board and its extension boards exceed the allowed current on the USB. -
