STM32 Nucleo-144 board
Introduction
The STM32 Nucleo-144 board (NUCLEO-F207ZG, NUCLEO-F303ZE, NUCLEO-F429ZI,
NUCLEO-F446ZE, NUCLEO-F746ZG, NUCLEO-F767ZI) provides an affordable and
flexible way for users to try out new ideas and build prototypes with the STM32
microcontroller, choosing from the various combinations of performance, power
consumption and features. The ST Zio connector, which extends the Arduino™ Uno
connectivity, and the ST morpho headers provide access to a wider range of peripherals
and make it easy to expand the functionality of the Nucleo open development platform with
a large choice of specialized shields. The STM32 Nucleo-144 board does not require any
separate probe as it integrates the ST-LINK/V2-1 debugger/programmer. The STM32
Nucleo-144 board comes with the STM32 comprehensive software HAL library, together
with various packaged software examples, as well as the direct access to the ARM® mbed™
on-line resources at http://mbed.org.

Cuttable PCB
The STM32 Nucleo-144 board is divided into two parts: ST-LINK and target STM32. The
ST-LINK part of the PCB can be cut out to reduce the board size. In this case the remaining
target STM32 part can only be powered by VIN, E5V and 3.3 V on ST morpho connector

to program the main STM32, using wires between CN6 and SWD signals available on ST
morpho connector (SWCLK CN11 pin 15, SWDIO CN11 pin 13 and NRST CN11 pin 14).

Embedded ST-LINK/V2-1
The ST-LINK/V2-1 programming and debugging tool is integrated in the STM32 Nucleo-144
boards.
The ST-LINK/V2-1 makes the STM32 Nucleo-144 boards mbed enabled.
The embedded ST-LINK/V2-1 supports only SWD for STM32 devices. For information about
debugging and programming features refer to ST-LINK/V2 in-circuit debugger/programmer
for STM8 and STM32, UM1075 User manual, which describes in details 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.
There are two different ways to use the embedded ST-LINK/V2-1, depending on the jumper
state (see Table 3):
•
Program/debug the STM32 on board
•
Program/debug the STM32 in an external application board, using a cable connected
to SWD connector CN6

Drivers
The ST-LINK/V2-1 requires a dedicated USB driver, which can be found on www.st.com for
Windows® XP, 7, 8.
In case the STM32 Nucleo-144 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 8), and from the device manager he must
update the driver of the connected device.
Note:
Prefer using the “USB Composite Device” handle for a full recovery.
Figure 8. Updating the list of drivers in Device Manager
6.3.2
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 functionalities, bug fixes, support for new microcontroller families), it is
recommended to visit www.st.com before starting to use the STM32 Nucleo-144 board and
periodically, in order to stay up-to-date with the latest firmware version.
6.3.3
Using the ST-LINK/V2-1 to program and debug
the STM32 on board
To program the STM32 on board, place on the connector CN4 the two jumpers marked in
red, as shown in Figure 9. The CN6 connector must not be used, since it could disturb the
communication with the STM32 microcontroller of the Nucleo-144 board.

Using ST-LINK/V2-1 to program and 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 CN4, as shown in Figure 10 and connect the
application to the CN6 debug connector according to Table 4.
Note:
SB111 NRST (target STM32 RESET) must be OFF when CN6 pin 5 is used in an external

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 (5 V) or +3V3 power supply pins on CN8 or CN11. In case VIN,
E5V or +3V3 is used to power the Nucleo-144 board, 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.
In case the power supply is +3V3, the ST-LINK is not powered and cannot be used.
6.4.1
Power supply input from ST-LINK/V2-1 USB connector
The STM32 Nucleo-144 board and shield can be powered from the ST-LINK USB connector
CN1 (U5V), by placing a jumper between the pins 3 and 4 of JP3, as shown in Table 7:
Power related jumper. 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-144 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 green LED LD6 is turned ON, thus the STM32 Nucleo-144 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 extension boards
are not power supplied. As a consequence the green LED LD6 stays turned OFF. In such
case it is mandatory to use an external power supply as explained in the next section.
After the USB enumeration succeeds, the ST-LINK U5V power is enabled, by asserting the
PWR_EN pin. This pin is connected to a power switch (ST890), which powers the board.
This power switch features also a current limitation to protect the PC in case of short-circuit
on board. If an overcurrent (more than 500 mA) happens on board, the red LED LD5 is lit.
JP1 is configured according to the maximum current consumption of the board when
powered by USB (U5V). JP1 jumper can be set ON to inform the host PC that the maximum
current consumption does not exceed 100 mA (including potential extension board or ST
Zio shield). In such condition USB enumeration will always succeed, since no more than
100 mA is requested to the PC. Possible configurations of JP1 are summarized in Table 5.

board, using an external power supply connected to E5V, VIN
or +3V3.
In case the board is powered by a USB charger, there is no USB enumeration, so the green
LED LD6 stays in OFF state permanently and the target STM32 is not powered. In this

specific case the jumper JP1 needs to be set to ON, to allow the board to be powered
anyway. But in any cases the current will be limited to 500 mA by U4 (ST890).
6.4.2
External power supply inputs
The Nucleo-144 board and its shield boards can be powered in three different ways from an
external power supply, depending on the voltage used. The three power sources are
summarized in the Table 6.
When STM32 Nucleo-144 board is power supplied by VIN or E5V, the jumper configuration
must be the following:
•
Jumper JP3 on pin 1 and pin 2 for E5V or jumper JP3 on pin 5 and pin 6 for VIN
•
Jumper JP1 OFF

Using VIN or E5V as an external power supply
When powered by VIN or E5V, it is still possible to use the ST-LINK for programming or
debugging only, but it is mandatory to power the board first using VIN or E5V, then to
connect the USB cable to the PC. By this way the enumeration will succeed anyway, thanks
to the external power source.
The following power sequence procedure must be respected:
1.
Connect jumper JP3 between pin 1 and pin 2 for E5V or between pin 5 and pin 6 for
VIN
2.
Check that JP1 is removed
3.
Connect the external power source to VIN or E5V
4.
Power on the external power supply 7V< VIN < 12V to VIN, or 5 V for E5V
5.
Check that the green LED LD6 is turned ON
6.
Connect the PC to the USB connector CN1
If this order is not respected, the board may be powered by USB (U5V) first, then by VIN or
E5V as the following risks may be encountered:
22/65
1.
If more than 300 mA current is needed by the board, the PC may be damaged or the
current supplied 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 LD6 remains OFF).

Hardware layout and configuration
External power supply input: + 3V3
Using the +3V3 (CN8 pin 7 or CN11 pin 16) directly as power input, can be interesting, for
instance, in case the 3.3 V is provided by a shield board. In this case, the ST-LINK is not
powered thus the programming and debug features are not available.
Two different configurations are possible to use +3V3 to power the board:
6.4.3
•
ST-LINK is removed (PCB cut)
•
SB3 (3V3 regulator) and SB111 (NRST) are OFF.
External power supply output
When powered by USB, VIN or E5V, the +5 V (CN8 pin 9 or CN11 pin 18) can be used as
output power supply for an ST Zio shield or an extension board. In this case, the maximum
current of the power source specified in Table 6: External power sources must be respected.
The +3.3 V (CN8 pin 7 or CN11 pin 16) can be used also as power supply output. The
current is limited by the maximum current capability of the regulator U6 (500 mA max).
6.5
LEDs
User LD1: a green user LED is connected to the STM32 I/O PB0 (SB120 ON and SB119
OFF) or PA5 (SB119 ON and SB120 OFF) corresponding to the ST Zio D13.
User LD2: a blue user LED is connected to PB7.
User LD3: a red user LED is connected to PB14.
These user LEDs are on when the I/O is HIGH value, and are off when the I/O is LOW.
LD4 COM: the tricolor LED LD4 (green, orange, red) provides information about ST-LINK
communication status. LD4 default color is red. LD4 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 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
LD5 USB power fault: LD5 indicates that the board power consumption on USB exceeds
500 mA, consequently the user must power the board using an external power supply.
LD6 PWR: the green LED indicates that the STM32 part is powered and +5 V power is
available on CN8 pin 9 and CN11 pin 18.
LD7 and LD8 USB FS: refer to Section 6.10: USB FS OTG or device.

6.7
JP5 (IDD)
Jumper JP5, labeled IDD, is used to measure the STM32 microcontroller consumption by
removing the jumper and by connecting an ammeter:
•
JP5 ON: STM32 is powered (default)
•
JP5 OFF: an ammeter must be connected to measure the STM32 current. If there is no
ammeter, the STM32 is not powered
To get a correct current consumption, the Ethernet PHY should be set in power-down mode
or SB13 should be removed. Refer to Section 6.11: Ethernet for details.

MCO from ST-LINK (Default): MCO output of ST-LINK is used as input clock. This
frequency cannot be changed, it is fixed at 8 MHz and connected to
PF0/PH0-OSC_IN of STM32 microcontroller. The following configuration is needed:
–
SB148 OFF
–
SB112 and SB149 ON
–
SB8 and SB9 OFF
HSE oscillator on-board from X3 crystal (not provided): for typical frequencies and
its capacitors and resistors, refer to the STM32 microcontroller datasheet and to the
AN2867 for the oscillator design guide. The X3 crystal has the following characteristics:
8 MHz, 8 pF, 20 ppm. It is recommended to use NX3225GD-8.000M-EXS00ACG04874 manufactured by NIHON DEMPA KOGYO CO., LTD. The following
configuration is needed:
–
SB148 and SB163 OFF
–
SB8 and SB9 soldered
–
C37 and C38 soldered with 4.3 pF capacitors
–
SB112 and SB149 OFF
Oscillator from external PF0/PH0: from an external oscillator through the pin 29 of
the CN11 connector. The following configuration is needed:
–
SB148 ON
–
SB112 and SB149 OFF
–
SB8 and SB9 removed

OSC 32 KHz clock supply
There are three ways to configure the pins corresponding to low-speed clock (LSE):
•
Note:
For STM32F0 and STM32F3 series it is recommended to use the low-drive mode
configuration of the LSE (low-drive capability in LSEDRV register), due to the 6 pF load
capacitance of the crystal on the board.
•
•
6.9
On-board oscillator (Default): X2 crystal. Refer to the AN2867 for oscillator design
guide for STM32 microcontrollers. It is recommended to use NX3214SA-32.768KHZEXS00A-MU00525 (32.768 KHz, 6 pF load capacitance, 200 ppm) from Nihon Dempa
Kogyo CO, LTD.
Oscillator from external PC14: from external oscillator through the pin 25 of CN11
connector. The following configuration is needed:
–
SB144 and SB145 ON
–
R37 and R38 removed
LSE not used: PC14 and PC15 are used as GPIOs instead of low-speed clock. The
following configuration is needed:
–
SB144 and SB145 ON
–
R37 and R38 removed
USART communication
The USART3 interface available on PD8 and PD9 of the STM32 can be connected to STLINK or to ST morpho connector. The choice can be changed by setting the related solder
bridges. By default the USART3 communication between the target STM32 and ST-LINK is
enabled, to support the virtual COM port for the mbed (SB5 and SB6 ON).

USB FS OTG or device
The STM32 Nucleo-144 board supports USB OTG or device-full-speed communication via
a USB Micro-AB connector (CN13) and USB power switch (U12) connected to VBUS.
Note:
NUCLEO-F303ZE supports the USB device FS only. All the other STM32 Nucleo-144
support the USB OTG.
Warning:
USB Micro–AB connector (CN13) cannot power the Nucleo144 board. In order to avoid damaging the STM32, it is
mandatory to power the Nucleo-144 before connecting a USB
cable on CN13. Otherwise there is a risk of current injection
on STM32 IOs.
A green LED LD8 will be lit in one of these cases:
•
Power switch (U12) is ON and STM32 Nucleo-144 board works as a USB host
•
VBUS is powered by another USB host when STM32 Nucleo-144 board works as a
USB device.
The red LED LD7 will be lit if overcurrent occurs when +5 V is enabled on VBUS in USB
host mode.
Note:
1. It is better to power Nucleo-144 board by an external power supply when using USB OTG
or host function.
2. JP4 must be closed when using USB OTG FS.
NUCLEO-F303ZE does not support OTG function but it supports USB 2.0 full-speeddevice-mode communication via a USB Micro-AB connector (CN13). USB disconnection
simulation can be implemented by PG6, which can control 1.5 K pull-up resistor (R70) on
USB D+ line. Detection of 5 V power on USB connector (CN13) is available on PG7 thanks
to R62 and R63 resistors bridge.

ESD protection part ESDA6V1BC6 is implemented on USB port because all USB pins on
STM32 can be used as VBUS or GPIO on STM32 Nucleo-144 board.
Note:
If these pins are dedicated to USB port only, the USBLC6-4SC6 protection part is more
suitable to protect USB port. If USB pin ID is not used, USBLC6-2SC6 can be used.
6.11
Ethernet
The STM32 Nucleo-144 board supports 10 M/100 M Ethernet communication by a PHY
LAN8742A-CZ-TR (U9) and RJ45 connector (CN14). Ethernet PHY is connected to the
STM32 microcontroller via the RMII interface. 50 MHz clock for the STM32 microcontroller
is generated by the PHY RMII_REF_CLK.
Note:
1. NUCLEO-F303ZE and NUCLEO-F446ZE do not support the Ethernet function.
2. JP6 and JP7 must be closed when using Ethernet.
3. Ethernet PHY LAN8742A should be set in power-down mode (Ethernet PHY ref clock will
be turned off in this mode) to achieve the expected low-power mode current. This is done by
configuring Ethernet PHY LAN8742A Basic Control Register (at address 0x00) Bit 11
(Power Down) to '1'. SB13 can be also removed to get the same effect.

ST Zio connectors
CN7, CN8, CN9 and CN10 are female on top side and male on bottom side connectors.
They include support for Arduino Uno Revision 3. Most shields designed for Arduino Uno
can fit to the STM32 Nucleo-144 boards.
To cope with Arduino Uno Revision 3, apply the following modifications:
Caution:
•
SB138 and SB143 should be ON
•
SB140/147/150/157/167/171 should be OFF to connect I2C on A4 (pin 5) and A5 (pin 6
of CN8).
The IOs of STM32 microcontroller are 3.3 V compatible instead of 5 V for Arduino Uno.
Table 12 to Table 16 show the pin assignment for each main STM32 microcontroller on the
ST Zio connectors.

1. Refer to Table 11: Solder bridges for details.
2. PA7 is used as D11 and connected to CN7 pin 14 by default, if JP6 is ON, it is also connected to both
Ethernet PHY as RMII_DV and CN9 pin 15. In this case only one function of the Ethernet or D11 could be
used.
3. PE2 is connected to both CN9 pin 14 (IO) and CN10 pin 25 (IO). Only one connector pin can be used at
one time.
4. PB13 is used as I2S_A_CK and connected to CN7 pin 5 by default, if JP7 is ON, it is also connected to
Ethernet PHY as RMII_TXD1. In this case only one function of Ethernet or I2S_A could be used.

ST morpho connector
The ST morpho connector consists in male pin header footprints CN11 and CN12 (not
soldered by default). They can be used to connect the STM32 Nucleo-144 board to an
extension board or a prototype/wrapping board placed on top of the STM32 Nucleo-144
board. All signals and power pins of the STM32 are available on the ST morpho connector.
This connector can also be probed by an oscilloscope, logical analyzer or voltmeter.
Table 17 and Table 18 show the pin assignment of each main STM32 on the ST morpho
connector.
