Arduino Uno WiFi Rev 2 / ABX00021

TheArduino Uno WiFi Rev 2 / ABX00021 is a modification of the familiar Arduino Uno Rev3, but with minor changes. The Arduino Uno WiFi Rev 2 is designed for educational projects in the field of the Internet of Things (IoT), which work using wireless communication and motion sensors. It will be useful for connecting to the network of indoor cottages, creating various devices for data transmission using BLE protocols, etc.

This controller will allow you to connect to a WiFi network using the ECC608 crypto accelerator of security algorithms. The Arduino Uno WiFi Rev 2 is functionally the same as the Arduino Uno Rev3, but with the addition of a WiFi network connection interface, Bluetooth and some other improvements. The controller is based on a new 8-bit microcontroller from Microchip and has a built-in IMU (Inertial Measurement Unit). The Wi-Fi module is a standalone SoC with a built-in TCP/IP protocol stack that can provide access to a Wi-Fi network or act as an access point.

Arduino UNO WiFi Rev.2 has 14 digital inputs/outputs (5 of which can be used as PWM outputs and 6 analog inputs), a USB connection, a power connector, an ICSP connector and a reset button.

To start working with this microcontroller, simply connect it to your computer using a USB cable, or plug in the AC adapter or battery.

The board is equipped with Microchip ATmega4809 microcontroller, so thanks to the level of compatibility included in the ATmega4809 core, it is possible to run all programs created for the UNO ATmega328P microcontroller.

A distinctive feature of this microcontroller is that, thanks to the Arduino UNO WiFi Rev.2 communication chipset, it can be both a client and a host device for BLE and Bluetooth® at the same time.

Another feature of this controller is that it is a dual-processor device, which provides flexible possibilities for its use and experimentation. Having the skills to firmware the module, you can, for example, modify the WiFiNINA module, which will allow you to use both WiFi and BLE/Bluetooth® on the board at the same time. WARNING: such hacking violates the certification of the WiFiNINA module, so keep in mind that you do this at your own risk.

Another possibility is to run an ultra-lightweight version of linux on the module, while the main microcontroller will control low-level devices (such as motors or expansion boards).
