STM32 Nucleo-144 boards
Introduction
The STM32 Nucleo-144 boards (NUCLEO-F207ZG, NUCLEO-F303ZE, NUCLEO-F412ZG,
NUCLEO-F413ZH, NUCLEO-F429ZI, NUCLEO-F439ZI, NUCLEO-F446ZE,
NUCLEO-F722ZE, NUCLEO-F746ZG, NUCLEO-F756ZG, NUCLEO-F767ZI and
NUCLEO-H743ZI) provide an affordable and flexible way for users to try out new concepts
and build prototypes, by choosing from the various combinations of performance and power
consumption features provided by the STM32 microcontroller. The ST Zio connector, which
extends the Arduino™Uno V3 connectivity, and the ST morpho headers provide an easy
means of expanding the functionality of the Nucleo open development platform with a wide
choice of specialized shields. The STM32 Nucleo-144 boards do not require any separate
probe as they integrate the ST-LINK/V2-1 debugger/programmer. The STM32 Nucleo-144
boards come with the comprehensive free software libraries and examples available with
the STM32Cube MCU Package, as well as a direct access to the Arm®Mbed Enabled™on-
line resources at http://mbed.org.

2 Product marking
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 design or in production.
“E” or “ES” marking examples of location:
•On the targeted STM32 that is soldered on the board (for 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.
This board features a specific STM32 device version which allows the operation of any
stack or library. This STM32 device shows a "U" marking option at the end of the standard
part number and is not available for sales.
3 Ordering information
To order the Nucleo-144 board corresponding to the targeted STM32, use the order code

5 Quick start
The STM32 Nucleo-144 board is a low-cost and easy-to-use development kit, used to
evaluate and start a development quickly with an STM32 microcontroller in LQFP144
package.
Before installing and using the product, accept the Evaluation Product License Agreement
from the www.st.com/epla webpage. For more information on the STM32 Nucleo-144 and
for demonstration software, visit the www.st.com/stm32nucleo webpage.
5.1 Getting started
Follow the sequence below to configure the Nucleo-144 board and launch the
demonstration application (for components location refer to Figure 4: Top layout):
1. Check jumper position on the board:
JP1 OFF (PWR-EXT) selected (see Section 6.4.1: Power supply input from ST-
LINK/V2-1 USB connector for more details)
JP3 on U5V (Power source) selected (for more details see Table 7: External power
sources)
JP5 ON (IDD) selected (for more details see Section 6.7: JP5 (IDD))
CN4 ON selected (for more details see Table 4: CN4 states of the jumpers)
2. For the correct identification of the device interfaces from the host PC and before
connecting the board, install the Nucleo USB driver available on the
www.st.com/stm32nucleo website.
3. To power the board connect the STM32 Nucleo-144 board to a PC with a USB cable
‘Type-A to Micro-B’ through the USB connector CN1 on the ST-LINK. As a result, the
green LED LD6 (PWR) and LD4 (COM) light up and the red LED LD3 blinks.

6.2 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
CN11, or VIN and 3.3 V on ST Zio connector CN8. It is still possible to use the ST-LINK part
to program the STM32, using wires between CN6 and SWD available signals on the ST
morpho connector (SWCLK CN11 pin 15, SWDIO CN11 pin 13 and NRST CN11 pin 14).

6.3 Embedded ST-LINK/V2-1
The ST-LINK/V2-1 programming and debugging tool is integrated in the STM32 Nucleo-144
board.
The ST-LINK/V2-1 makes the STM32 Nucleo-144 board 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, User manual (UM1075), 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 100mA power on USB
Features not supported on ST-LINK/V2-1:
•SWIM interface
•Minimum supported application voltage limited to 3 V
There are two different ways to use the embedded ST-LINK/V2-1, depending on the jumper
state (see Table 4):
•Program/debug the STM32 on board
•Program/debug the STM32 in an external application board, using a cable connected
to SWD connector CN6
6.3.1 Drivers
Before connecting the Nucleo-144 board to a Windows 7, Windows 8 or Windows XP PC
via USB, a driver for ST-LINK/V2-1 must be installed. It can be downloaded from the
www.st.com website.
In case the STM32 Nucleo-144 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-144 board to this dedicated driver,
must be updated in the device manager manually.
Note: It is recommended to proceed using USB Composite Device, as shown in Figure 8.
Table 4. CN4 states of the jumpers
Jumper state Description
Both CN4 jumpers ON ST-LINK/V2-1 functions enabled for on-board programming
(default). See Section 6.3.3.
Both CN4 jumpers OFF ST-LINK/V2-1 functions enabled for external CN6 connector
(SWD supported). See Section 6.3.4.

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 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 the
STM32 Nucleo-144 board. The latest version of this firmware is available from the
www.st.com website.
6.3.3 Using the ST-LINK/V2-1 to program and debug the on-board STM32
To program the on-board STM32, place the two jumpers marked in red on the connector
CN4, 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.

6.3.4 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 5.
Note: SB111 NRST (target STM32 RESET) must be OFF when CN6 pin 5 is used in an external
application.

6.4 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 (7 V-12 V), E5V (5 V) or +3.3 V power supply pins on CN8 or CN11. In case VIN,
E5V or +3.3 V 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.
