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.

Let’s connect at The Things Conference 2023
Let’s connect at The Things Conference 2023
September 13, 2023

It’s time to catch up on all things LoRaWAN® and low-power IoT! Our team is looking forward to returning to The Things Conference this year, joining all LoRa® key players in Amsterdam on September 21st-22nd. Our experts will be showcasing new products and applications relevant to the technology that is putting the “smart” in smart cities, smart agriculture, smart logistics, and more. Indeed, with IoT’s huge growth potential in both B2B and B2C applications, LoRaWAN® is stepping up as one of the technologies of the future. Already established as the low-power connectivity choice, according to The Things Network it is reaping the benefits of innovations that increase efficiency even further – and is poised to support ESG (environmental, social and governance) goals with reduced energy consumption and secure data transmission. LoRaWAN® novice, or expert? We’ve got you covered Whether you are just realizing the potential of LoRaWAN® or have been a fan of it since day one (like us!), we’ll have something for you to discover at our booth at The Things Conference: Looking for an entry-level option? The Arduino MKR WAN 1310 offers you the renowned versatility of the practical and cost-effective MKR family and adds LoRa® connectivity to projects requiring low power.Ready to take it up a notch? The solution for advanced applications requiring sturdy computational power is to boost Arduino Pro’s Portenta H7 module (in any of its three variants) with the capability to run embedded computer vision applications, connect wirelessly via LoRa® to the Arduino Cloud (or third-party infrastructure), and activate systems upon the detection of sound events. How? With the Portenta Vision Shield LoRa®, of course!Feel the need for high performance? Pair the Portenta Max Carrier with a Portenta X8 module to add LoRa® connectivity to your project, transforming your robust SOM into a single-board computer or reference design enabling edge AI for
