When Arduino Meets STM32

In the 21st century, technology has advanced rapidly. The microcontrollers in the hands of geeks have evolved from the old 51 and PIC to AVR and STM32, along with various convenient development tools, such as the once-popular Arduino. However, the Atmega328-based AVR microcontroller is still quite outdated, being almost 20 years old, while ARM is now in vogue. Today, we will discuss a product born from the encounter of Arduino and STM32 - the Olimexino
