Wiki,Tutorial,Program,Code,User Guide (Click here)

Overview

[] The new Arduino UNO R4 comes in two versions: the UNO R4 WiFi and the UNO R4 Minima. It runs on the Renesas RA4M1 (Arm Cortex-M4) processor, with a clock speed of 48MHz, which provides a 3x increase over the UNO R3. In addition to that, the SRAM has been upgraded from 2kB to 32kB and the flash memory has been increased from 32kB to 256kB to accommodate to more complex projects. Furthermore, in response to requests from the Arduino community, the USB port has been upgraded to USB-C and the maximum power supply voltage has been increased to 24V. The board provides a CAN bus, allowing users to minimize wiring and perform different tasks by connecting multiple extension boards. Finally, the new board also includes a 12-bit analog DAC.

[] The WiFi version is equipped with the Espressif S3 WiFi module, providing manufacturers, educators, and enthusiasts with more creative opportunities.

[] The UNO R4 Minima provides a cost-effective option for those seeking new microcontrollers without additional features.

[] Building on the success of UNO R3, UNO R4 is the best prototype and learning tool for everyone. While retaining the known characteristics of the UNO series (standard form factor, shielding compatibility, 5V voltage, robustness), new features have been added.

[] Thanks to its powerful design and reliable performance, the UNO R4 is a valuable addition to the Arduino ecosystem, suitable for beginners and experienced electronics enthusiasts alike to deploy their own projects.

UNO R4 Features


[] Hardware compatibility with UNO form factor

The UNO R4 Minima maintains the same form factor, pinout, and 5 V operating voltage as its predecessor, the UNO R3. This ensures a seamless transition for existing shields and projects, leveraging the extensive and unique ecosystem already established for the Arduino UNO.


[] Expanded memory and faster clock

Prepare for more precise calculations and the ability to handle complex projects with ease. The UNO R4 Minima boasts increased memory and a faster clock speed, empowering you to tackle demanding tasks effortlessly.


[] Extra on-board peripherals

The UNO R4 Minima introduces a range of on-board peripherals, including a 12-bit DAC, CAN BUS, and OP AMP. These additional components provide you with expanded capabilities and flexibility in your designs.


[] Communicate with human-machine interaction devices through USB-C

UNO R4 can simulate a mouse or keyboard when connected to its USB-C port


[] Extended 24 V tolerance

The UNO R4 Minima now supports a wider input voltage range, allowing power supplies up to 24 V. This enables seamless integration with motors, LED strips, and other actuators, simplifying your projects by utilizing a single power source.


[] SWD connector

Debugging is a critical aspect of any project. Simply connect an external debugger to the UNO R4 Minima and effortlessly monitor the inner workings of your system. Stay in control and gain valuable insights.


UNO R4 WiFi Features


[] Equipped with WiFi and Bluetooth functions

The UNO R4 WiFi has an ESP32-S3-MINI coprocessor that enhances the functionality of the RA4M1 microcontroller. Equipped with WiFi and Bluetooth connectivity capabilities, developers can easily connect to the internet and create IoT projects.


[] Onboard 12x8 LED matrix

The UNO R4 WiFi board is equipped with a bright 12x8 red LED matrix (a total of 96 points). This feature is very suitable for creative projects that use animation or draw sensor data, without the need for any additional hardware.


[] QwiicI2C connector

The UNO R4 WiFi board is equipped with an industry standard Qwiic I2C connector for easy and fast prototyping design. Through I2C connection, various compatible modules can be connected, allowing creators to easily create custom projects and expand the functionality of UNO R4 WiFi.


[] Runtime error diagnosis

The UNO R4 WiFi board has a built-in error capture mechanism, which can detect operations that may cause the board to crash, such as Division by zero. When an error is detected, the board will print a detailed error description and reason on the serial monitor.


[] Supports battery powered RTC

UNO R4 has additional pins that can turn off the main microcontroller while keeping the internal RTC powered by an external battery


UNO R4 Minima Features


[] Cost-effective

The UNO R4 Minima provides a cost-effective option for those seeking new microcontrollers without additional features.


[] SWD connector

The onboard SWD port provides manufacturers with a simple and reliable way to connect third-party debugging probes. This feature ensures the reliability of the project and allows for efficient debugging of any potential issues.
