Mouser Electronics supplies Arduino products for industrial automation and IoT prototyping.

Mouser announced on the 12th that it is supplying Arduino's UNO R4 microcontroller board. Powered by Renesas' RA4M1 32-bit Arm® Cortex®-M4 processor, the Uno R4 offers superior processing performance with a clock speed of 48 MHz.

The Uno R4 is equipped with 32kB of SRAM and 256kB of flash memory, making it suitable for more complex projects.

In addition, the performance of specific applications can be significantly improved through the Floating Point Unit (FPU) of the microcontroller core.

The Uno R4 microcontroller board can be used as an embedded platform supporting a wide range of applications, including industrial automation, Internet of Things (IoT) devices, robotics, weather monitoring, smart agriculture, and artificial intelligence (AI), and is particularly suitable for prototyping.

The Arduino Uno R4 is supplied in two versions, the Uno R4 Minima and the fully featured Uno R4 WiFi, to meet the needs of both budget-conscious users and those who wish to add unique features.

The Uno R4 Minima is a cost-effective solution for users looking to improve processing performance without additional features.

The Uno R4 WiFi includes Espressif’s S3 WiFi module for WiFi and Bluetooth® Low Energy connectivity.

It also supports a bright 12x8 red LED matrix, making it very suitable for displaying sensor data without using additional display hardware.

In addition, the Uno R4 WiFi supports the numerous Uno shield ecosystems already on the market, as well as various compatibility options via the Qwiic I2C connector. It can be connected to modules, allowing you to create projects in an excellent plug-and-play (PnP) manner without soldering, breadboards, or manual wiring.

In addition, for advanced users, an additional pin is provided to turn off the microcontroller while maintaining RTC power with an external buffer battery.

The Uno R4 supports enhanced processing performance and memory capable of handling complex tasks and calculations, and since the board operates on a 5V input voltage, it can be easily integrated with existing projects and components.

The Uno R4 is built with the same form factor as the Uno R3, making it compatible with existing shields and accessories.

In addition, Uno R4 supports software extensibility to easily upgrade projects implemented on Uno R3 or Leonardo.
