Arduino Uno R4 is the Next Generation of Microcontroller

Written by Stephen Vicinanza

Arduino Uno R4 is the next generation of microcontrollers. The Uno R4 is the latest addition to the Arduino microcontroller (MCU) lineup. This board is a significant update to the Arduino lineup. It is suitable for both industrial applications and the ever-popular Arduino educational purposes and has many new features and improvements.

The Uno R4 is running an ARM Cortex M4 processor, a 32-bit MCU that operates at 5 volts. This setup allows the users to rescue existing Arduino shields without any compatibility issues. There is also a Native USB interface, which removes the need for an external chip for USB serial conversion. This can mimic a keyboard or mouse, which is an added incentive for creative projects.

The Arduino Uno R4 features the inclusion of the ESP32 S3 Wi-Fi and Bluetooth module. That addition once connected to an LED display matric, with a quick connector for sensor modules makes the R4 a very versatile project board or addition to an industrial lineup of sensor data collection or IoT systems.

The R4 is already available and is an affordable microcontroller at $27.50 USD. The board retains the ease of use that Arduino is known for and is an excellent board for the beginner or established developer alike.
