ST STM32G4 Nucleo-32 Manual de usuario
Introduction
The STM32G4 Nucleo-32 board (NUCLEO-G431KB) provides an affordable and flexible way for users to try out new concepts
and build prototypes, by choosing from the various combinations of performance, power consumption and features provided by
the STM32G4 Series microcontroller. The ARDUINO® Nano V3 connectivity provides easy means of expanding the functionality
of the Nucleo open development platform with a wide choice of specialized shields. The STM32G4 Nucleo-32 board does not
require any separate probe as it integrates the STLINK-V3E debugger/programmer. The STM32G4 Nucleo-32 board comes
with the comprehensive free software libraries and examples available with the STM32CubeG4 MCU Package.

2.1 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 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.
2.2 Codification
The meaning of the codification is explained in Table 2.

5Quick start
The STM32G4 Nucleo-32 board is a low-cost and easy-to-use development kit, used to evaluate and start a
development quickly with an STM32G4 Series microcontroller in LFQFPN 32-pin 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 STM32G4 Nucleo-32 and for demonstration software, visit the www.st.com/stm32nucleo
webpage.
5.1 Getting started
Follow the sequence below to configure the STM32G4 Nucleo-32 board and launch the demonstration application
(refer to Figure 4 for component location):
1. Check the jumper position on the board (refer to Table 4).
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 STM32G4 Nucleo-32 board to a PC with a USB cable (Type-A to Micro-B)
through the USB connector CN1 of the board.
4. Then, LED LD1 (COM) and green LED LD4 (5V_PWR) light up, green LED LD2 blinks.
5. Remove the jumper placed between D2 (CN4 pin 5) and GND (CN4 pin 4).
6. Observe how the blinking of the green LED LD2 changes, when the jumper is in place or removed.
7. Download the software demonstration software and several software examples that help to use the STM32
Nucleo features. These are available on the NUCLEO-G431KB webpage
8. Develop your own application using the available examples
