Arduino Uno R4 MINIMA / Arduino Uno WIFI Microcontroller Techmakers

Arduino® Uno R4 WiFi The Arduino UNO R4 WiFi combines the processing power and exciting new peripherals of the RA4M1 microcontroller from Renesas with the wireless connectivity of the ESP32-S3 from Espressive. On top of this, the UNO R4 WiFi shows an on-board 12x8 LED matrix, Qwiic connector, VRTC, and OFF pin, covering all the potential makers will have for their next project.

Arduino® Uno R4 Minimum Enhanced and improved, the Arduino UNO R4 Minimal is armed with a powerful 32-bit microcontroller courtesy of Renesas. Brace self for increased processing power, expanded memory, and a whole new level of on-board peripherals. The best parts? Compatibility with existing shields and accessories stays intact, and there's no need to make any changes to the standard form factor or 5V operating voltage.
