![]() One of the first aspects that we can note is the presence of many contacts on card’s border, including the now famous female contacts connector compatible with the Arduino shield. Each NUCLEO board differs for performances, power consumption, clock frequency and flash memory capacity of the STM32 microcontroller in figure.įrom here on, we will analyze the NUCLEO model F401 and we will move our first programming steps, but many of the aspects and features that we will see later will be valid for any other NUCLEO board. The whole series of NUCLEO development boards is equipped with a STM32 microcontroller based on ARM Cortex-M family, adopting a 32-bit RISC architecture. The board name comes from the microcontroller mounted on the board ( STM32F401) which is its heart. ![]() We will also see how to program it and test it by using some development environments available and a first sample program. In this post we will examine the NUCLEO F401RE board that is among the best performing in the series, not only because it is based on an ARM processor with a 84 MHz clock, a 512 Kb flash memory and an integrated floating-point unit, but also for a number of interesting features that we will see together. Some of these boards are simple clones, other are at much higher level having better performances and memory storage.Īmong those, a really interesting solution is represented by the development boards family called NUCLEO made by STMicroelectronics, a semiconductors leader company. The success of Arduino and its countless shields, kicked off in recent years the birth of several compatible development boards designed to help us creating in a short time, at low cost and easily, great and even complex electronic applications. *This information is for general informational purposes only, we will not be liable for any loss or damage caused by the above information.Today we present the first steps with the NUCLEO development boards, produced by STMicroelectronics, that can help us to move towards the ARM 32-bit world with simplicity and great performances, keeping a compatibility with Arduino expansion connectors so that we can use its commonly available shields. The company offers a wide range of products including microcontrollers, sensors, power amplifiers, and integrated circuits for various applications in the automotive, industrial, and consumer markets.įounded in 1987, STMicroelectronics has operations in over 100 countries and is one of the largest semiconductor companies in the world. STMicroelectronics is a multinational electronics and semiconductor manufacturer based in Geneva, Switzerland. SPI display expansion boards for STM32 Nucleo-64 Support of wide choice of Integrated Development Environments (IDEs) including IAR™, ARM® Keil®, GCC-based IDEs.Three different interfaces supported on USB: – USB communication (LD1), user LED (LD2), power LED (LD3) ![]() – USB VBUS or external source (3.3V, 5V, 7 - 12V) – Selection-mode switch to use the kit as a standalone ST-LINK/V2-1 On-board ST-LINK/V2-1 debugger/programmer with SWD connector:.– ST morpho extension pin headers for full access to all STM32 I/Os The STM32 Nucleo board comes with the STM32 comprehensive software HAL library together with various packaged software examples, as well as direct access to the ARM® mbed™ online resources at. The STM32 Nucleo board does not require any separate probe as it integrates the ST-LINK/V2-1 debugger and programmer. The Arduino™Uno V3 connectivity support and the ST morpho headers allow to expand easily the functionality of the STM32 Nucleo open development platform with a wide choice of specialized shields. The STM32 Nucleo board provides an affordable and flexible way for users to try out new concepts and build prototypes with the STM32 microcontroller, choosing from the various combinations of performance, power consumption and features.
