ABX00021 - ARDUINO UNO WIFI R2 BOARD

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

Bluetooth® and Bluetooth® Low Energy: The communications chipset on the Arduino UNO WiFi Rev.2 can function as both a Bluetooth® and Bluetooth® Low Energy client and host device. This is a unique feature in the world of microcontroller platforms. Explore the ArduinoBLE library for examples of creating a Bluetooth® central or peripheral device.

Add this board to a device to connect it to a Wi-Fi network using its secure ECC608 crypto chip accelerator. The Arduino UNO WiFi Rev.2 is functionally similar to the Arduino Uno Rev3, with additional features like Wi-Fi/Bluetooth® connectivity and other enhancements. It incorporates the ATmega4809 8-bit microcontroller from Microchip and includes an onboard IMU (Inertial Measurement Unit) LSM6DS3TR.

The Wi-Fi Module is a self-contained SoC with an integrated TCP/IP protocol stack, allowing access to a Wi-Fi network or acting as an access point. The module is the u-blox NINA-W102 (datasheet available).

The Arduino UNO WiFi Rev.2 has 14 digital input/output pins—5 of which 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.
