ST-LINK part of the PCB can be cut out to reduce the board size. In this case the remaining
target MCU part can only be powered by VIN, E5V and 3.3V on STMicroelectronics Morpho
connector CN7 or VIN and 3.3V on Arduino connector CN6. It is still possible to use the ST-
LINK part to program the main MCU using wires between CN4 and SWD signals available
on STMicroelectronics Morpho connector (SWCLK CN7 pin 15 and SWDIO CN7 pin 13).

5.2 Embedded ST-LINK/V2-1
The ST-LINK/V2-1 programming and debugging tool is integrated in the STM32 Nucleo
boards.
The ST-LINK/V2-1 makes the STM32 Nucleo boards mbed enabled.
The embedded ST-LINK/V2-1 supports only SWD for STM32 devices. For information about
debugging and programming features refer to UM1075 - ST-LINK/V2 in-circuit
debugger/programmer for STM8 and STM32, User manual, which describes in detail all the
ST-LINK/V2 features.
The changes versus ST-LINK/V2 version are listed below.
•New features supported on ST-LINK/V2-1:
– USB software re-enumeration
– Virtual com port interface on USB
– Mass storage interface on USB
– USB power management request for more than 100 mA power on USB
•Features not supported on ST-LINK/V2-1:
–SWIM interface
– Minimum supported application voltage limited to 3 V
•Known limitation:
– Activating the readout protection on ST-Link/V2-1 target prevents the target
application from running afterwards. The target readout protection must be kept
disabled on ST-Link/V2-1 boards.
There are two different ways to use the embedded ST-LINK/V2-1 depending on the jumper
states (see Table 3 and Figure 5):
•Program/debug the MCU on board (Section 5.2.2),
•Program/debug an MCU in an external application board using a cable connected to
SWD connector CN4 (Section 5.2.4).

5.2.1 Drivers
The ST-LINK/V2-1 requires a dedicated USB driver, which can be found on www.st.com for
Windows XP, 7, 8. On Windows XP the ST-LINK/V2-1 driver requires WinUsb to be installed
before using the ST-LINK/V2-1 (either available from Microsoft website or included in the
USB driver for ST-LINK/V2 for XP).
In case the STM32 Nucleo board is connected to the PC before the driver is installed, some
Nucleo interfaces may be declared as “Unknown” in the PC device manager. In this case
the user must install the driver files (Figure 6), and from the device manager update the
driver of the connected device.
Note: Prefer using the “USB Composite Device” handle for a full recovery.
Figure 6. Updating the list of drivers in Device Manager
5.2.2 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 life time of the ST-LINK/V2-1 product (for
example new functionality, bug fixes, support for new microcontroller families), it is
recommended to visit www.st.com before starting to use the STM32 Nucleo board and
periodically, in order to stay up-to-date with the latest firmware version.

5.2.3 Using the ST-LINK/V2-1 to program/debug the STM32 on board
To program the STM32 on the board, plug in the two jumpers on CN2, as shown in red in
Figure 7. Do not use the CN4 connector as this could disturb the communication with the
STM32 microcontroller of the STM32 Nucleo board.
Figure 7. Connecting the STM32 Nucleo board to program the on-board STM32
5.2.4 Using ST-LINK/V2-1 to program/debug an external STM32 application
It is very easy to use the ST-LINK/V2-1 to program the STM32 on an external application.
Simply remove the two jumpers from CN2 as illustrated in Figure 8, and connect your
application to the CN4 debug connector according to Table 4.
Note: SB12 NRST (target MCU RESET) must be OFF if you use CN4 pin 5 in your external
application.

5.3 Power supply and power selection
The power supply is provided either by the host PC through the USB cable, or by an
external Source: VIN (7V-12V), E5V (5V) or +3V3 power supply pins on CN6 or CN7. In
case VIN, E5V or +3V3 is used to power the Nucleo board, using an external power supply
unit or an auxiliary equipment, this power source must comply with the standard EN-60950-
1: 2006+A11/2009, and must be Safety Extra Low Voltage (SELV) with limited power
capability.
5.3.1 Power supply input from the USB connector
The ST-LINK/V2-1 supports USB power management allowing to request more than
100 mA current to the host PC.

UM1724 Hardware layout and configuration

All parts of the STM32 Nucleo board and shield can be powered from the ST-LINK USB
connector CN1 (U5V or VBUS). Note that only the ST-LINK part is power supplied before
the USB enumeration as the host PC only provides 100 mA to the board at that time. During
the USB enumeration, the STM32 Nucleo board requires 300 mA of current to the Host PC.
If the host is able to provide the required power, the targeted STM32 microcontroller is
powered and the red LED LD3 is turned ON, thus the STM32 Nucleo board and its shield
can consume a maximum of 300 mA current, not more. If the host is not able to provide the
required current, the targeted STM32 microcontroller and the MCU part including the
extension board are not power supplied. As a consequence the red LED LD3 remains
turned OFF. In such case it is mandatory to use an external power supply as explained in
the next chapter.
When the board is power supplied by USB (U5V) a jumper must be connected between pin
1 and pin 2 of JP5 as shown in Table 7.
JP1 is configured according to the maximum current consumption of the board when
powered by USB (U5V). JP1 jumper can be set in case the board is powered by USB and
maximum current consumption on U5V doesn’t exceed 100mA (including an eventual
extension board or Arduino Shield). In such condition USB enumeration will always succeed
since no more than 100mA is requested to the PC. Possible configurations of JP1 are
summarized in Table 5.
Warning: If the maximum current consumption of the NUCLEO and its
extension boards exceeds 300 mA, it is mandatory to power
the NUCLEO using an external power supply connected to
E5V or VIN.
Note: In case the board is powered by an USB charger, there is no USB enumeration, so the led
LD3 remains set to OFF permanently and the target MCU is not powered. In this specific
case the jumper JP1 needs to be set to ON, to allow target MCU to be powered anyway.
5.3.2 External power supply inputs: VIN and EV5
The external power sources VIN and EV5 are summarized in the Table 6. When the board is
power supplied by VIN or E5V, the jumpers configuration must be the following:
Jumper on JP5 pin 2 and pin 3
Jumper removed on JP1

JP1 jumper OFF
USB power through CN1
300 mA max
JP1 jumper ON 100 mA max
Hardware layout and configuration UM1724
18/63 DocID025833 Rev 7
Using VIN or E5V as external power supply
VIN or E5V can be used as external power supply in case the current consumption of
NUCLEO and extensions boards exceeds the allowed current on USB. In this condition it is
still possible to use the USB for communication, for programming or debugging only, but it is
mandatory to power supply the board first using VIN or E5V then connect the USB cable to
the PC. Proceeding this way ensures that the enumeration occurs thanks to the external
power source.
The following power sequence procedure must be respected:
1. Connect the jumper between pin 2 and pin 3 of JP5.
2. Check that JP1 is removed.
3. Connect the external power source to VIN or E5V.
4. Power on the external power supply 7 V< VIN < 12 V to VIN, or 5 V for E5V.
5. Check that LD3 is turned ON.
6. Connect the PC to USB connector CN1.
If this order is not respected, the board may be supplied by VBUS first then by VIN or E5V,
and the following risks may be encountered:

1. If more than 300 mA current is needed by the board, the PC may be damaged or the
current supply can be limited by the PC. As a consequence the board is not powered
correctly.
2. 300 mA is requested at enumeration (since JP1 must be OFF) so there is risk that the
request is rejected and the enumeration does not succeed if the PC cannot provide
such current. Consequently the board is not power supplied (LED LD3 remains OFF).

5.3.3 External power supply input: + 3V3
It can be of interest to use the +3V3 (CN6 pin 4 or CN7 pin 12 and pin 16) directly as power
input for instance in case the 3.3 V is provided by an extension board. When NUCLEO is
power supplied by +3V3, the ST-LINK is not powered thus the programming and debug
features are unavailable. The external power sources +3.3V is summarized in the Table 8.
Two different configurations are possible to use +3V3 to power the board:
•ST-LINK is removed (PCB cut), or
•SB2 (3V3 regulator) & SB12 (NRST) are OFF.
5.3.4 External power supply output
When powered by USB, VIN or E5V, the +5V (CN6 pin 5 or CN7 pin 18) can be used as
output power supply for an Arduino shield or an extension board. In this case, the maximum
current of the power source specified in Table 6 needs to be respected.
The +3.3 V (CN6 pin 4 or CN7 pin 12 & 16) can be used also as power supply output. The
current is limited by the maximum current capability of the regulator U4 (500 mA max).
5.4 LEDs
The tricolor LED (green, orange, red) LD1 (COM) provides information about ST-LINK
communication status. LD1 default color is red. LD1 turns to green to indicate that
communication is in progress between the PC and the ST-LINK/V2-1, with the following
setup:
•Slow blinking Red/Off: at power-on before USB initialization
•Fast blinking Red/Off: after the first correct communication between the PC and ST-
LINK/V2-1 (enumeration)
•Red LED On: when the initialization between the PC and ST-LINK/V2-1 is complete
•Green LED On: after a successful target communication initialization
•Blinking Red/Green: during communication with target
•Green On: communication finished and successful.
•Orange On: Communication failure
User LD2: the green LED is a user LED connected to Arduino signal D13 corresponding to
MCU I/O PA5 (pin 21) or PB13 (pin 34) depending on the STM32 target. Please refer to
Table 10 to Table 19.
•When the I/O is HIGH value, the LED is on.
•When the I/O is LOW, the LED is off.
LD3 PWR: the red LED indicates that the MCU part is powered and +5V power is available.

5.5 Push buttons
B1 USER: the user button is connected to the I/O PC13 (pin 2) of the STM32
microcontroller.
B2 RESET: this push button is connected to NRST, and is used to RESET the STM32
microcontroller.
Note: The blue and black plastic hats that are placed on the push buttons can be removed if
necessary, for example when a shield or when an application board is plugged on top of
NUCLEO. This will avoid pressure on the buttons and consequently a possible permanent
target MCU RESET.
5.6 JP6 (IDD)
Jumper JP6, labeled IDD, is used to measure the STM32 microcontroller consumption by
removing the jumper and by connecting an ammeter.
•Jumper ON: STM32 microcontroller is powered (default).
•Jumper OFF: an ammeter must be connected to measure the STM32 microcontroller
current. If there is no ammeter, STM32 microcontroller is not powered.

5.7 OSC clock
5.7.1 OSC clock supply
There are four ways to configure the pins corresponding to external high-speed clock
external high-speed clock (HSE):
•MCO from ST-LINK: MCO output of ST-LINK MCU is used as input clock. This
frequency cannot be changed, it is fixed at 8 MHz and connected to PF0/PD0/PH0-
OSC_IN of STM32 microcontroller.
The following configuration is needed:
– SB54 and SB55 OFF
– SB16 and SB50 ON
– R35 and R37 removed
•HSE oscillator on-board from X3 crystal (not provided): for typical frequencies and
its capacitors and resistors, please refer to STM32 microcontroller datasheet. Please
refer to the AN2867 for oscillator design guide for STM32 microcontrollers.The X3
crystal has the following characteristics: 8 MHz, 16 pF, 20 ppm, and DIP footprint. It’s
recommended to use 9SL8000016AFXHF0 manufactured by Hong Kong X'tals
Limited.
The following configuration is needed:
– SB54 and SB55 OFF
– R35 and R37 soldered
– C33 and C34 soldered with 20 pF capacitors
– SB16 and SB50 OFF
•Oscillator from external PF0/PD0/PH0: from an external oscillator through pin 29 of
the CN7 connector.
The following configuration is needed:
–SB55 ON
–SB50
OFF
– R35 and R37 removed
•HSE not used: PF0/PD0/PH1 and PF1/PD1/PH1 are used as GPIO instead of Clock
The following configuration is needed:
– SB54 and SB55 ON
– SB16 and SB50 (MCO) OFF
– R35 and R37 removed
There are two possible default configurations of the HSE pins depending on the version of
NUCLEO board hardware.
The board version MB1136 C-01 or MB1136 C-02 is mentioned on sticker placed on bottom
side of the PCB.
The board marking MB1136 C-01 corresponds to a board, configured for HSE not used.
The board marking MB1136 C-02 (or higher) corresponds to a board, configured to use ST-
LINK MCO as clock input.

Note: For NUCLEO-L476RG the ST-Link MCO output is not connected to OSCIN to reduce power
consumption in low power mode. Consequently NUCLEO-L476RG configuration
corresponds HSE not used.
5.7.2 OSC 32 kHz clock supply
There are three ways to configure the pins corresponding to low-speed clock (LSE):
•On-board oscillator: X2 crystal. Please refer to the AN2867 for oscillator design guide
for STM32 microcontrollers.with the following characteristics: 32.768 kHz, 6 pF,
20 ppm, and SM308 footprint. It is recommended to use ABS25-32.768KHZ-6-T
manufactured by Abracon corporation.
•Oscillator from external PC14: from external oscillator through the pin 25 of CN7
connector.
The following configuration is needed:
– SB48 and SB49 ON
– R34 and R36 removed
•LSE not used: PC14 and PC15 are used as GPIOs instead of low speed Clock.
The following configuration is needed:
– SB48 and SB49 ON
– R34 and R36 removed
There are two possible default configurations of the LSE depending on the version of
NUCLEO board hardware.
The board version MB1136 C-01 or MB1136 C-02 is mentioned on sticker placed on bottom
side of the PCB.
The board marking MB1136 C-01 corresponds to a board configured as LSE not used.
The board marking MB1136 C-02 (or higher) corresponds to a board configured with on-
board 32kHz oscillator.
The board marking MB1136 C-03 (or higher) corresponds to a board using new LSE crystal
(ABS25) and C26, C31 & C32 value update.
5.8 USART communication
The USART2 interface available on PA2 and PA3 of the STM32 microcontroller can be
connected to ST-LINK MCU, STMicroelectronics Morpho connector or to Arduino connector.
The choice can be changed by setting the related solder bridges. By default the USART2
communication between the target MCU and ST-LINK MCU is enabled in order to support
Virtual Com Port for mbed (SB13 and SB14 ON, SB62 and SB63 OFF). If the
communication between the target MCU PA2 (D1) or PA3 (D0) and shield or extension
board is required, SB62 and SB63 should be ON, SB13 and SB14 should be OFF. In such
case it possible to connect another USART to ST-LINK MCU using flying wires between
Morpho connector and CN3. For instance on NUCLEO-F103RB it is possible to use
USART3 available on PC10 (TX) & PC11 (RX). Two flying wires need to be connected as
follow:
•PC10 (USART3_TX) available on CN7 pin 1 to CN3 pin RX
•PC11 (USART3_RX) available on CN7 pin 2 to CN3 pin TX

5.11 Arduino connectors
CN5, CN6, CN8 and CN9 are female connectors compatible with Arduino standard. Most
shields designed for Arduino can fit to the STM32 Nucleo boards.
The Arduino connectors on STM32 Nucleo board support the Arduino Uno Revision 3.
For compatibility with Arduino Uno Revision 1, apply the following modifications:
•SB46 and SB52 should be ON,
•SB51 and SB56 should be OFF to connect I2C on A4 (pin 5) and A5 (pin 6 of CN8).
Caution: The IOs of STM32 microcontroller are 3.3 V compatible instead of 5 V for Arduino Uno.
Table 10 to Table 19 show the pin assignment of each main STM32 microcontroller on
Arduino connectors.
