Arduino UNO R4 WiFi Original (New 2023-2024)

Here is the newest member of the UNO family, the Arduino UNO R4 board! Keeping the same format that everyone is already familiar with, the most famous board in the world of electronics will revolutionize maker's projects, expanding the already wide horizons of the R3 version. This novelty combines a new microcontroller, the RA4M1, from the Renesas brand, more advanced when compared to the previous AtMega328p, with the ESP32-S3, in a partnership between Arduino and Espressif; that eliminates the old limitations of the UNO series, the lack of native connectivity to the Internet and the absence of a Bluetooth module, for the control of kits with robots. With this new model, you can easily develop from a simple server to a data logger for the cloud.

Looking more closely at this novelty, it also has a small matrix of 12x8 LEDs on the board itself, with the possibility of showing shapes and figures, without resorting to any type of external module! Read the temperature and display it directly on the plate!

Do you want to use UNO as a clock or alarm clock? This detail was carefully thought out! The Arduino UNO R4 has an RTC (Real Time Clock) built into the microcontroller itself, it is only necessary to power the VRTC pin on the board. Want more fun? Are the already included extras not enough? It's time to try the new Qwiic connector, with I2C connection, so that the expansion of your project becomes easy and practical, all through a simple cable, compatible with countless existing modules.

When it comes to connections, we cannot remain indifferent with the abolition of the USB type B port for programming/powering our famous Arduino board. Thinking about a standardized future, the adoption of a USB-C port is always welcome!
