The Arduino for your educational projects with wireless connectivity and motion sensing.

Overview

The Arduino UNO WiFi Rev.2 is the easiest point of entry to basic IoT with the standard form factor of the UNO family. Whether you are looking at building a sensor network connected to your office or home router, or if you want to create a Bluetooth® Low Energy device sending data to a cellphone, the Arduino UNO WiFi Rev.2 is your one-stop-solution for many of the basic IoT application scenarios.

Add this board to a device and you'll be able to connect it to a WiFi network, using its secure ECC608 crypto chip accelerator. The Arduino Uno WiFi is functionally the same as the Arduino Uno Rev3, but with the addition of WiFi / Bluetooth® and some other enhancements. It incorporates the brand new ATmega4809 8-bit microcontroller from Microchip and has an onboard IMU (Inertial Measurement Unit) LSM6DS3TR.

The Wi-Fi Module is a self-contained SoC with integrated TCP/IP protocol stack that can provide access to a Wi-Fi network, or act as an access point. It is the u-blox NINA-W102 and (here) you find the datasheet.

The Arduino UNO WiFi Rev.2 has 14 digital input/output pins—5 can be used as PWM outputs—6 analog inputs, a USB connection, a power jack, an ICSP header, and a reset button. It contains everything needed to support the microcontroller. Simply connect it to a computer with a USB cable or power it with an AC adapter or battery to get started.

 

Compatibility

This board has the Microchip ATmega4809 microcontroller, but thanks to the compatibility layer included in the core, you can run all the sketches made for the UNO's ATmega328P microconntroller on the ATmega4809. You can find more information about the usage of this mode in the Getting Started page of the Arduino UNO WiFi Rev.2

 

Bluetooth® and Bluetooth® Low Energy

The communications chipset on the Arduino UNO WiFi Rev.2  can be both a Bluetooth® and Bluetooth® Low Energy client and host device. Something pretty unique in the world of microcontroller platforms. If you want to see how easy it is to create a Bluetooth® central or a peripheral device, explore the examples at our ArduinoBLE library.

We Make it Open for you to Hack Along

The Arduino UNO WiFi Rev.2 is a dual processor device that invites for experimentation. Hacking the WiFiNINA module allows you to, for example, make use of both WiFi and Bluetooth® and Bluetooth® Low Energy at once on the board. Yet another possibility is having a super-lightweight version of linux running on the module, while the main microcontroller controls low level devices like motors, or screens. These experimental techniques, require advanced hacking on your side. They are possible via modifying the module's firmware that you can find at our github repositories.

BEWARE: this kind of hacking breaks the certification of your WiFiNINA module, do it at your own risk.

Related Boards

If you are looking at upgrading from previous Arduino designs, or if you are just interested in boards with similar functionality, at Arduino you can find:

  • MKR WiFi 1010: the small form factor version of the Arduino UNO WiFi Rev.2, with a battery connector and an additional I2C port. Read more here.
  • Nano 33 IoT: if you need an even smaller form factor, this board sacrifices the battery connector, but the basic functionality is essentially the same. Visit its product page here.
  • MKR WiFi 1000: can only run WiFi applications, as it includes a different chipset than the MKR WiFi 1010. Read more about it here.

Getting Started

The Getting Started section contains all the information you need to configure your board, use the Arduino Software (IDE), and start tinkering with coding and electronics.

Arduino partners with RS/OKdo strategically to further expand the China market
Arduino partners with RS/OKdo strategically to further expand the China market
November 4, 2024

Arduino is excited to announce a strategic new partnership with RS/OKdo, a prominent leader in the distribution of industrial and electronic equipment. This collaboration marks a significant step forward in bringing Arduino’s technology closer to China’s thriving maker community and enterprise sector, offering enhanced local support and access to original Arduino boards and resources. Empowering a growing community in China With over 2.7 million active users of the Arduino IDE in China, one of our top priorities is to deliver an even better experience for the Arduino Community. This partnership with RS/OKdo means users will enjoy more local language content, technical support, competitive pricing, and most importantly, easier access to official Arduino products. Official Arduino boards, certified for China As part of this initiative, a range of classic and most popular Arduino boards has been specifically manufactured for the Chinese market. These boards are exactly the same as Arduino’s global versions of the same products, produced in Italy to Arduino’s highest standards, tested rigorously for quality and performance. Each product , although certified exclusively for the Chinese market, matches the same technical specifications and high-quality benchmarks as those sold worldwide. The boards are available only through RS/OKdo and Arduino/OKdo’s authorized sub-distributors. They have unique Arduino MPNs but with a _CN suffix: Arduino UNO R4 Wifi (ABX00087_CN) Arduino UNO R4 Minima (ABX00080_CN) Arduino UNO R3 (A000066_CN) Arduino Nano ESP32 with (ABX00083_CN) and without (ABX00092_CN) headers Arduino Nano R3 (A000005_CN) Arduino Mega 2560 (A000067_CN) Arduino DUE (A000062_CN) Front & back of official UNO R4 WiFi - SKU ABX00087_CN Front & back of official UNO R3 - SKU A000066_CN Expanding local support for enterprise transformation In addition to supporting makers, RS/OKdo will provide enhanced
