The Arduino Uno Wi-Fi Rev2 is an Uno Micro-controller Board With an Incorporated Wi-Fi module. The Uno WiFi Rev2 is designed to ease the installation of software that requires WiFi connectivity utilizing the timeless Arduino form variable and is perfect for emerging IoT (Web of Things) sectors like agriculture, automotive, consumer electronics, smart house, and wearables. As Well as the onboard Micro Chip Technology ECC608 CryptoAuthentication IC, the Micro-controller also provides hardware-based security for connecting jobs to the cloud-like AWS along with Google.
The Uno Wi Fi Rev2 is based upon the MicroChip Technology ATmega4809 8-Bit Micro-controller. WiFi 802.11b/g/n connectivity is supplied through an onboard u-Blox NINA-W13 Module. The NINA-W13 Module is itself contained System-on-Chip (SoC) having an incorporated TCP/IP protocol stack, allowing access to the WiFi network. The device also can serve as an entry point. The Uno wi fi Rev2 also has aid for OTA (over the air ) programming, and possibly for its transfer of Arduino sketches or wi fi firmware.
