External power supply input
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 to 12 V) from the ARDUINO ® or ST morpho connector
E5V from the ST morpho connector
5V_USB_CHG from the ST-LINK USB connector
3.3 V from the ARDUINO ® or ST morpho connector
If an external 5 V DC power source is used, the Nucleo board must be powered by a power supply unit or by a piece of auxiliary equipment complying with the EN-60950-1: 2006+A11/2009 standard and must be safety extra ‑ low voltage (SELV) with limited power capability.

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 JP5 jumper must be on pins 1 and 2 to select the STLK power source on the JP5 silkscreen. This is the default setting. If the USB enumeration succeeds, the STLK power is enabled, by asserting the PWR_ENn signal coming from the STM32F103CBT6 ST-LINK microcontroller. This pin is connected to an
STMPS2141STR power switch, which powers the board. This power switch also features a current limitation to protect the PC in case of a short-circuit on board, detected with current higher than 750 mA.
The STM32 Nucleo-64 board and its shield are powerable from the CN1 ST-LINK USB connector, but only the
ST-LINK circuit is powered before USB enumeration because the host PC only provides 100 mA to the board at that time. During the USB enumeration, the STM32 Nucleo-64 board requires 500 mA of current from the host PC. If the host can provide the required power, the enumeration ends by a SetConfiguration command and then, the STMPS2141STR power transistor is switched ON, the LD3 green LED is turned ON, thus the
STM32 Nucleo-64 board and its shield request no more than 500 mA current. If the host is not able to provide the required current, the enumeration fails. Therefore the power switch transistor stays OFF and the MCU part including the extension board is not powered. As a consequence, the LD3 green LED stays turned OFF. In this case, it is mandatory to use an external power supply.
USB power: STLK configuration: Jumper JP5 [1-2] (STLK silkscreen) must be connected as shown in

Programming/debugging when the power supply is not from ST-LINK
VIN is the 7 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 JP5 jumper must be [3-4] to select the VIN power source on the
JP5 silkscreen. In that case, the DC power comes from the power supply through the ARDUINO ® Uno V3 battery shield and is compatible with Adafruit ® PowerBoost 500 shield.
VIN configuration: The JP5 jumper [3-4] (VIN silkscreen) must be connected as shown in
E5V is the DC power coming from an external source (5V DC power from pin 6 of the CN7 ST morpho connector). In this case, the JP5 jumper must be [5-6] to select the E5V power source on the JP5 silkscreen.
E5V configuration: The JP5 jumper [5-6] (E5V silkscreen) must be connected as shown in
5V_USB_CHARGER is the DC power charger connected to the CN1 USB ST-LINK connector. To select the CHG power source on the JP5 silkscreen, the JP5 jumper must be [7-8]. In this case, if the STM32 Nucleo-64 board is powered by an external USB charger the debug is not available. If the PC is connected instead of the charger, the limitation is no more effective and the PC can be damaged.
CHG configuration: The JP5 jumper [7-8] (CHG silkscreen) must be connected as shown in
•
•
External power supply output
5V: The 5V present on CN6 pin 5 or CN7 pin 18 is usable as a power supply output for an ARDUINO ® shield or an extension board when the STM32 Nucleo-64 board is powered by USB, VIN, or E5V. In this case, the maximum current allowed is shown in
.
3.3V: The 3V3 present on CN6 pin 4 or CN7 pin 16 is usable as a power supply output. The current is limited by the maximum current capability of the U6 regulator (LDL112PV33R from STMicroelectronics). In this condition, the maximum consumption of the STM32 Nucleo-64 board and the connected shield current must be lower 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. In such a condition, it is still possible to use the USB for communication, programming, or debugging only. In this case, it is mandatory to power the board first using VIN or E5V then to connect the USB cable to the PC. Proceeding this way the enumeration succeeds, thanks to the external power source. The following power sequence procedure must be respected:
•
•
•
•
•
Connect the JP5 jumper [3-4] for VIN or [5-6] for E5V,
Connect the external power source to VIN or E5V,
Power ON the external power supply 7 V < VIN < 12 V to VIN, or 5 V for E5V,
Check that the LD3 green LED is turned ON,
Connect the PC to the CN1 USB connector.
If this sequence is not respected, the board may be powered by V
BUS
first from ST-LINK, with the following risks:
•
•
If a higher than 500 mA current is needed by the board, the PC may be damaged or the current supplied may be limited by the PC. As a consequence, the board is not powered correctly.
500 mA is requested at the enumeration since SB1 must be OFF. This request is rejectable and the enumeration does not succeed if the PC does not provide such current. Consequently, the board is not power supplied and LD3 LED remains OFF.

OSC clock sources
Three clock sources are listed below:
LSE which is the 32.768 kHz crystal for the STM32 embedded RTC,
MCO which is the 8 MHz clock from the ST-LINK MCU for the STM32 microcontroller,
HSE which is the 48 MHz oscillator for the STM32 microcontroller.

LSE clock reference
There are three ways to configure the pins corresponding to the low-speed clock (LSE):
1.
LSE on-board X2 crystal (Default configuration). Refer to the application note Oscillator design guide for
STM8AF/AL/S, STM32 MCUs and MPUs ( AN2867 ) for crystal design guide for STM32 microcontrollers.
2.
Oscillator from external to PC14 input, from external oscillator through pin 25 of the CN7 connector. The following configuration is needed:
– SB3 ON
– R31 and R32 OFF
3.
LSE not used. PC14 and PC15 are used as GPIOs instead of low ‑ speed clocks. The following configuration is needed:
– SB3 and SB4 ON
– R31 and R32 OFF
HSE clock reference
There are four ways to configure the pins corresponding to the external high ‑ speed clock (HSE):
1.
HSE not used: PF0 and PF1 are used as GPIOs instead of clocks. The configuration must be:
– SB5 and SB6 ON
– SB29 (MCO) OFF
– R33 and R34 OFF
2.
MCO from ST-LINK: MCO output of ST-LINK is used as an input clock. This frequency cannot be changed, it is fixed at 8 MHz and connected to the PF0-OSC_IN of the STM32 microcontroller. The configuration must be:
– SB29 ON
– SB5 and SB6 OFF
– R33 and R34 OFF
3.
HSE on-board oscillator from X3 crystal (default). For typical frequencies, capacitors, and resistors, refer to the STM32 microcontroller datasheet and the application note Oscillator design guide for STM8AF/AL/S,
STM32 MCUs and MPUs ( AN2867 ) for the oscillator design guide. The X3 crystal has the following characteristics: 48 MHz, 7 pF, and 20 ppm. The configuration must be:
– SB5 and SB6 OFF
– R33 and R34 ON
– C25 and C26 ON with 4.3 pF capacitors
– SB29 OFF
4.

LEDs
Four LEDs are available on the STM32 Nucleo-64 board. The four LEDs are located on the top side of the board:
1.
LD1 COM: LD1 is a bi-colored LED. the LD1 default status is red. LD1 turns to green to indicate that communication is in progress between the PC and the ST-LINK/V2-1 as follow:
– Slow blinking red and OFF: At power-on before USB initialization
– Fast blinking red and OFF: After the first correct communication between the PC and the ST-LINK/V2-1
(enumeration)
– Red LED ON: When initialization between the PC and the ST-LINK/V2-1 successfully ends
– Green LED ON: After successful STM32 communication initialization
– Blinking red and green: During communication with STM32
– Green ON: Communication successfully ends.
– Orange ON: Communication ends with failure.
2.
LD2 5V_USB_CHG: This red LED is ON when overcurrent is detected on USB V
BUS information that more than 500 mA is requested on V
BUS
. The LED gives the
. In this case, it is recommended to supply the board with E5V, VIN, or in USB_CHARGER mode.
3.
LD3 5V_PWR: This green LED is ON when the STM32 Nucleo-64 board is powered by a 5 V source.
4.
LD4 USER: This green LED is a user LED connected to D13 ARDUINO ® signal corresponding to PA5
STM32 I/O. To light the LED a HIGH logic state must be written in the corresponding GPIO. A transistor is used to drive the LED when the I/O voltage is 1.8 V. LD4 consumption does not impact the VDD STM32 power measurement, since LD4 is isolated from it.
Push ‑ buttons
Two push ‑ buttons:
1.
B1 USER: User and wake-up button connected to the PC13 I/O pin 3 of the STM32 microcontroller
2.
B2 RESET: Push ‑ button connected to NRST is used to reset the STM32 microcontroller.
The blue and black plastic hats placed on these push ‑ buttons are removable if necessary when a shield or an application board is plugged on top of the Nucleo board. This avoids pressure on the buttons and consequently a possible permanent target MCU reset.

STM32 Nucleo-64 board information
STM32 Nucleo-64 board information
Product marking
The stickers located on the top or bottom side of the PCB provide product information:
• Product order code and product identification for the first sticker
• Board reference with revision, and serial number for the second sticker
On the first sticker, the first line provides the product order code, and the second line the product identification.
On the second sticker, the first line has the following format: “MBxxxx-Variant-yzz”, where “MBxxxx” is the board reference, “Variant” (optional) identifies the mounting variant when several exist, "y" is the PCB revision and "zz" is the assembly revision, for example B01. The second line shows the board serial number used for traceability.
Evaluation tools marked as “ES” or “E” are not yet qualified and therefore not ready to be used as reference design or in production. Any consequences deriving from such usage will not be at ST charge. In no event, ST will be liable for any customer usage of these engineering sample tools as reference designs or in production.
“E” or “ES” marking examples of location:
•
•
On the targeted STM32 that is soldered on the board (For an illustration of STM32 marking, refer to the
STM32 datasheet “Package information” paragraph at the www.st.com
website).
Next to the evaluation tool ordering part number that is stuck or silk-screen printed on the board.
Some boards feature a specific STM32 device version, which allows the operation of any bundled commercial stack/library available. This STM32 device shows a "U" marking option at the end of the standard part number and is not available for sales.
In order to use the same commercial stack in his application, a developer may need to purchase a part number specific to this stack/library. The price of those part numbers includes the stack/library royalties.
