Arduino vs STM32

source link

Arduino and STM32 are both popular microcontroller platforms, but they have some key differences.

Arduino is an open-source electronics platform based on simple microcontroller boards. It is designed for hobbyists and beginners, it is easy to use, and has a large community of users and developers. Arduino boards have a wide range of compatible shields, which are add-on boards that can be used to add functionality to the microcontroller. The Arduino boards are usually based on AVR or SAM microcontrollers, and they have a simple and easy-to-use IDE (Integrated Development Environment) and a large library of pre-written code.

STM32 is a family of 32-bit microcontroller integrated circuits by STMicroelectronics. It is designed for professional use in a wide range of applications, including industrial, medical, and automotive. STM32 boards are based on ARM Cortex-M microcontrollers, which are more powerful and complex than the microcontrollers used in Arduino boards. The STM32 boards have a more advanced development environment and toolchain, which is geared toward professional use. They also have a large number of peripherals and interfaces that are not available on Arduino boards, such as USB, Ethernet, and CAN bus.

In summary, Arduino is more suited for hobbyists and beginners while STM32 is more geared towards professionals and advanced users that require more powerful and complex solutions.
