STM32 Nucleo-64-P boards
Introduction
The STM32 Nucleo-64-P boards (NUCLEO-L412RB-P, NUCLEO-L433RC-P and
NUCLEO-L452RE-P) provide an affordable and flexible way for users to try out new
concepts and build prototypes with the STM32 microcontroller and the external SMPS
(switched mode power supply), which provides various combinations of performance, power
consumption and features.
Arduino™ Uno V3 connectivity and 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-64-P boards do not require any separate probe, as they integrate the
ST-LINK/V2-1 debugger/programmer. The STM32 Nucleo-64-P boards come with the
comprehensive free STM32 software libraries and examples that are available with the
STM32Cube package.

2 Product marking
Evaluation tools marked as "ES" or "E" are not yet qualified and therefore they are 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 section “Package characteristics” of the STM32 datasheet at www.st.com).
• 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
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.

UM2206 Quick start
8 Quick start
This section describes how to start a development quickly using the STM32 Nucleo-64-P
board.
Before installing and using the product, accept the Evaluation Product License Agreement
from the www.st.com/epla webpage.
8.1 Getting started
The STM32 Nucleo-64-P board is a low-cost and easy-to-use development kit to quickly
evaluate and start a development with an STM32 microcontroller in QFP64 package. To
start using this board, follow the steps below:
1. Check the jumper position on the board, as showed in the Table 4: Default jumper
settings
2. For a correct identification of all device interfaces from the host PC, install the Nucleo
USB driver available on the www.st.com/ stm32nucleo webpage, prior connecting the
board.
3. To power the board connect the Nucleo-64-P board to a PC with a USB cable ‘type A to
micro-B’ through the USB connector CN1. As a result the green LED LD3 (5
lights up, LD1 (COM) and green LED LD4 blink.
4. Press user button B1 (blue).
5. Observe that the blinking frequency of the three green LED LD4 changes, by clicking
on the button B1.
6. The software demonstration and the several software examples, that allow the user to
use the Nucleo features, are available at the www.st.com/stm32nucleo webpage.
7. Develop an application using the available examples.

9 Hardware layout and configuration
The STM32 Nucleo-64-P board is designed around the STM32 microcontrollers in a
64-pins LQFP package.
Figure 3 illustrates the connection between the STM32 and the peripherals (ST-LINK/V2-1,
push-buttons, LEDs, Arduino Uno V3 connector and ST morpho connectors).
Figure 4 and Figure 5 show the location of these features on the STM32 Nucleo-64-P

9.3 Cuttable PCB
An STM32 Nucleo-64-P 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 V
CN5, or by V
It is still possible to use the ST- LINK part to program the STM32, using wires between the
CN3 and SWD available signals on the ST morpho connector (SWCLK CN5 pin 17, SWDIO
CN5 pin 15 and NRST CN5 pin 14, same I/O level as V
and 3.3 V Arduino connector CN8.

9.4 Embedded ST-LINK/V2-1
The ST-LINK/V2-1 programming and debugging tool is integrated on the
STM32 Nucleo-64-P board.
For information about debugging and programming features, refer to ST-LINK/V2 in-circuit
debugger/programmer for
website.
The changes versus ST-LINK/V2 version are listed below.
New features supported on ST-LINK/V2-1 are:
• 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
The following features are no more supported on ST-LINK/V2-1:
• SWIM interface
• Application voltage lower than 3 V (need to add level shifter to support it)

UM2206 Hardware layout and configuration
The embedded ST-LINK/V2-1 can be used in two different ways according to the jumper
states (refer to
Tabl e 5):
• Program/debug the STM32 on board,
• Program/debug an STM32 in an external application board using a cable connected to
SWD connector.

9.4.1 Drivers
®
Before connecting the STM32 Nucleo-64-P board to a Windows
through USB, install the driver for
the ST-LINK/V2-1 that is available at the www.st.com
website.
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.
Note: It is recommended to proceed by using USB Composite Device, as shown in Figure 7.

PC (XP, 7, 8 and 10)
9.4.2 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 an
STM32 Nucleo-64-P board. The latest version of this firmware is available at the www.st.com
website.

To program the STM32, place the two jumpers marked in red on the connector CN2, as
shown in

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 shown in Figure 9, and connect the
application to the SWD debug connector according to Tab le 6.
