This is an official and genuine Arduino UNO board, made by authorized manufacturer.
The Arduino UNO R4 WiFi is another variant under the Uno R4 range which is an updated version for the popular and beginner-friendly Arduino UNO. It is a small, affordable, and easy-to-use development board powered by the Renesas RA4M1 32-bit ARM Cortex-M4 processor, providing a significant boost in processing power, memory, and functionality.
This board also has a secondary processor on-board which is the ESP32-S3 WiFi module for wireless connectivity (Bluetooth Low Energy and WiFi). This feature allows you to embark on IoT projects in no time.
The other useful features of this board are the 12x8 LED matrix that you can use to display texts and graphics and a Qwiic connector that you use to connect sensors or other peripherals.
The UNO R4 WiFi is perfect for beginners and experienced makers alike. It's easy to get started with, thanks to the large community of Arduino users and the wealth of resources available online. And with its powerful features, the UNO R4 Minima can be used to create a wide variety of projects, from simple LED blinkers to complex robotics systems. The board has 14 digital I/O pins (6 of them can be used as PWM outputs), 6 analog inputs, a 16 MHz quartz crystal, a USB connector, a regular DC power jack and a reset button.
How do I power this board?
To power the board, you can connect it to a PC using a USB Type A to USB-C cable. This is especially used when you want to upload your Arduino program to the board.
Another way to power this board is using the a DC power supply such as wall plug or a battery connected to the DC barrel jack (5.5mm x 2.1mm, center positive). The DC barrel jack for Arduino UNO can accept a wider range of voltage from 6V to 24V. This is our recommended power supply.
How do I program this board?
The Arduino UNO can be programmed using the Arduino IDE.
