Arduino Uno R4 WiFi is an original Arduino Uno module with an efficient 32-bit Renesas RA4M1 ARM Cortex M4 microcontroller. The board has 256 kB Flash memory and 32 kB SRAM memory, 14 digital inputs/outputs including 6 PWM, 6 ADC and 1 DAC. It has popular communication interfaces such as SPI, I2C, UART and CAN. It works with 5V voltage. The ESP32-S3-Mini system is responsible for WiFi and Bluetooth connectivity. The Uno R4 WiFi has a matrix of addressable red 12x8 LEDs and a Qwiic connector.
Main features of original Arduino Uno R4 modules
- Backward Hardware Compatibility - Arduino Uno R4 has the same pinout and logic voltage (5V) as Arduino Uno R3. This means that all overlays and designs can be easily transferred to a new version of the board.
- New Board Features – The Uno R4 version includes several new features such as a 12-bit digital-to-analog converter (DAC), CAN BUS, OP AMP and SWD debug port. Thanks to them, you can significantly expand the functionality of your projects.
- More Memory and Faster Processor – Increased memory (16x) and processor clock speed (3x) allow for more accurate calculations and more complex projects.
- HID over USB-C - Arduino Uno R4 allows you to emulate a mouse and keyboard over USB Type-C This feature allows you to create an interesting user interface with minimal effort.
- High supply voltage range - Uno R4 boards can be powered up to 24V. The circuit is equipped with a number of protective measures that minimize the risk of damage to the board or PC due to incorrect user connected wiring. The RA4M1 microcontroller also has overcurrent protection.
- Capacitive Touch Support – The RA4M1 microcontroller used in the Arduino Uno R4 natively supports capacitive touch.
What makes the Arduino Uno R4 WiFi unique?
- WiFi and Bluetooth wireless connection - Uno R4 WiFi is equipped with an ESP32-S3-Mini coprocessor that allows you to create IoT projects thanks to WiFi and Bluetooth wireless connection.
- 12x8 LED matrix - the board has a 12x8 matrix of bright red LEDs (96 points in total). This is an ideal feature for creative projects using animation or plotting data from sensors, without the need for additional elements.
- Qwiic connector - The Arduino Uno R4 WiFi has a built-in Qwiic I2C socket, which allows you to quickly and easily connect I2C modules equipped with the same connector to the board, without the need for soldering.
- Real-time error diagnostics - The board has an error-catching mechanism that detects operations that may cause it to fail, e.g. division by zero. When an error is detected, the board will print a detailed explanation of the error and its cause on the serial monitor.
Plug and Play
The Arduino Uno R4 WiFi board is equipped with a Qwiic connector that allows you to connect one or more available modules from the wide Qwiic ecosystem. Modules from other ecosystems such as Grove can also be connected using the appropriate adapter.
Combined with the well-known ecosystem of Arduino Uno boards, the Uno R4 WiFi becomes a very versatile platform for creating projects without the need for a breadboard or soldering.
