Short description

Summarize this content to 100 words At the end of June 2023, Arduino released the Uno R4 board – an update of the classic platform for developing DIY projects and learning microcontroller development. The board now runs on a 32-bit microcontroller and provides more features out of the box.The Uno R4 is powered by a 32-bit Arm Cortex M4 microcontroller. This gives developers a 16x increase in memory and a 3x increase in clock speed compared to the classic Uno board. And this allows us to implement more complex projects.Arduino Uno R4 MinimaThe Uno R4 also provides a number of additional ports, including a CAN bus, an op-amp and an SWD port. The connection to the PC is implemented using USB-C. The updated version of the Uno can work as a HID device by default. At the same time, the company’s engineers managed to keep the usual size of the board and the working voltage of 5 V.Arduino releases the Uno R4 in two versions: Minima and Wi-Fi. The first offers basic capabilities for beginner developers, while the Wi-Fi version claims the following additional features:Wi-Fi and Bluetooth support, implemented on the basis of the ESP32-S3 coprocessor, which allows you not to borrow the resources of the main microcontroller;12×8 LED matrix, which can be used to implement monitoring systems of connected sensors;Qwiic connector designed for quick debugging;built-in error detection system. For example, if the board detects a division by zero in the code, the system will stop the code execution before it causes serious problems and malfunctions. Along with stopping the operation of the board, the user will receive a detailed description of the error.Arduino Uno R4 Wi-FiBoards can be purchased in the official Arduino store. Yes, the Minima version will cost $20, and the Wi-Fi version will cost $27. The company also said that community members are already actively adapting libraries for the Uno R4.
