Arduino is a microcomputer board developed with the aim of making it easy for even beginners to use. It consists of a board with input and output, a microcomputer (MCU), Arduino's own language, and a development environment. The Arduino UNO is Arduino's flagship product and the Arduino UNO R4 is its fourth version.

There are two types of Arduino UNO R4, the basic configuration 'UNO R4 Minima' and the 'UNO R4 WiFi' equipped with a Wi-Fi module.



The previous generation Arduino UNO R3 used the 8-bit microcomputer

ATmega328P as the MCU, but the Arduino UNO R4 is equipped with the ' Renesas RA4M1 ' that includes a 32-bit Arm Cortex-M4 core. And the RAM is 32KB, which is 16 times more than the previous generation. In addition, the flash memory is now 256KB, an eight-fold increase over the previous generation.



``With 16x more memory and 3x the clock speed, the Arduino UNO R4 performs more precise calculations and can handle more complex and sophisticated projects than ever before,'' Arduino said.

In addition, a USB-C connector is used for the power supply connector. The operating voltage is still 5V, but the input voltage is now 6-24V. Built-in peripherals include a 12-bit D/A converter , CAN BUS , and operational amplifier . And since it uses a 32-bit Arm-based MCU, it has a new SWD connector, but hardware compatibility such as operating voltage and form factor is maintained so that existing shields and projects can be used. It is said that there is.

In addition, it has built-in HID (Human Interface Device) support, so you can simulate a mouse and keyboard by connecting it to your computer via USB. This makes it easier to send keystrokes and mouse movements to your computer, improving usability and functionality.

Arduino UNO R4 will be sold in Japan from June 27, 2023. However, at the time of writing the article, only `` Arduino UNO R4 Minima '' was released, and `` Arduino UNO R4 WiFi '' equipped with functions such as Wi-Fi communication was released after obtaining technical certification. In addition, Arduino Uno R4 Minima is 3190 yen including tax and can be purchased from the following page.
