What is nucleo?

Nucleo is a line of development boards designed and manufactured by STMicroelectronics. These boards are intended to provide a easy-to-use and cost-effective way to evaluate and prototype STM32 microcontroller-based projects. They typically feature an STM32 microcontroller, programming interface, power management circuitry, and a wide variety of interfaces and features, such as USB, CAN, Ethernet, and more. Nucleo boards are compatible with the Arduino ecosystem, including development tools like the Arduino Integrated Development Environment (IDE), and libraries. Additionally, they can be used with a variety of software development tools, such as Keil, IAR Embedded Workbench, and STM32CubeIDE. Nucleo boards are suitable for a wide range of applications, from consumer electronics to industrial control systems, robotics, and more.
