The Arduino UNO R4 boards feature a powerful 32-bit microcontroller that provides more computing power and memory, while maintaining the standard UNO form factor and 5 V operating voltage.
As such, it is an excellent option for beginners and experienced electronics enthusiasts who want to expand the limits of their projects.
While the well-known characteristics of the UN family are maintained, the UNO R4 boards offer a 32-bit architecture and exciting new features forManufacturer.
The Arduino UNO R4 boards are equipped with a powerful 32-bit microcontroller from Renesas, which provides more computing power, memory and on-board peripherals.
It is important that these improvements do not affect compatibility with existing shields and accessories, nor do they require changes to the standard form factor or the 5 V operating voltage.
With its rugged design and reliable performance, the UNO R4 is a valuable addition to the Arduino ecosystem.
It is suitable for beginners as well as for experienced electronics enthusiasts, who want to extend the limits of their projects.
Backwards compatible hardwareThe UNO R4 has the same pin assignment and 5V operating voltage as its predecessor, the Arduino UNO R3.
This means that existing shields and projects can easily be ported to the new board.
New on-board peripheralsThe UNO R4 has several exciting new peripherals, including a 12-bit DAC, CAN BUS, OP AMP and SWD port.
These additions extend the opportunities for developers and enable more advanced projects.
More memory and faster speedWith more memory (16x) and faster clock speed (3x), the UNO R4 minima can perform more precise calculations and process more complex projects.
This allows developers to create even more sophisticated and advanced projects.
HID VIA USB-CThe UNO R4 can simulate a mouse or keyboard when connected to the USB-C connector.
With this feature, makers can create fast and cool interfaces with minimal effort.
Higher voltage range and electrical robustnessThe UNO R4 boards can be operated with up to 24 V, also thanks to an improved theme design.
The circuit is equipped with several protective devices to reduce the risk of wiring faults by inexperienced users damaging the circuit board or the PC.
In addition, the RA4M1 micro-controller has an overcurrent protection on the pins, which offers additional protection against errors.
Support for capacitive touchThe RA4M1 microcontroller, used on the UNO R4 boards, supports capacitive touch from the house.
WiFi and Bluetooth capabilitiesThe UNO R4 WiFi features an ESP32-S3 MINI coprocessor, which extends the capabilities of the RA4M1 microcontroller.
With Wi-Fi and Bluetooth connectivity, this board enables easy connection to the Internet and IoT project creation.
12x8 LED matrix on boardThe UNO R4 WiFi has a bright 12x8 red LED matrix (total of 96 points).
This feature is Ideal for creative projects with animations or for recording sensor data without the need for additional hardware.
Qwic I2C connectionThe UNO R4 WiFi features a Qwic industry standard I2C connector that enables rapid prototyping.
With a wide range of compatible modules that can be connected via I2C, developers can easily create their own projects and extend the capabilities of the UNO R4 WiFi.
Diagnostics for runtime errorsThe UNO R4 WiFi has a built-in error trap mechanism that detects operations that may cause the board to crash, such as Division by zero.
If an error is detected, the board prints a detailed explanation of the error and its causes on the serial monitor.
