Arduino Uno WiFi rev 2 [4] ATMEGA4809, NINA-W132 Wi-Fi module from u-blox, ECC608 crypto device 16 MHz Arduino / Genuino 68.6 mm × 53.4 mm [ 2.7 in × 2.1 in ] USB-A 32U4 5 V 48 0.25 6 FH 14 5 6 0 Announced May 17, 2018: Contains six-axis accelerometer, gyroscope the NINA/esp32 module supports Wi-Fi and support Bluetooth as Beta feature [5]
The ATmega328P MPU and ATmega4809 MCU are rated for a maximum of 20 MHz, but the Uno R3 and Uno WiFi R2 boards both operate at 16 MHz. The following Arduino boards have a 32.768 kHz crystal too: Uno WiFi R2, Zero, Due, GIGA R1 WiFi. The Uno R4 Minima has SMD footprints for a 32.768KHz crystal and two capacitors, but aren't installed.
Arduino Mega compatible board with 16 extra I/O pins and the same a board size as the Arduino Uno. As with the Arduino Mega, most shields that were designed for the Duemilanove, Diecimila, or Uno will fit, but a few shields will not fit because of interference with the extra pins.

Wi-Fi microcontrollers enable Wi-Fi connectivity for devices so that they can send & receive data and accept commands. As such, Wi-Fi microcontrollers can be used for bringing otherwise ordinary devices into the realm of the Internet of things. Wi-Fi microcontroller chips:
A wireless Internet service provider (WISP) is an Internet service provider with a network based on wireless networking. Technology may include commonplace Wi-Fi wireless mesh networking , or proprietary equipment designed to operate over open 900 MHz , 2.4 GHz , 4.9, 5, 24, and 60 GHz bands or licensed frequencies in the UHF band (including ...
Many of these systems interface with consumer electronics such as the Arduino or Raspberry Pi, which are easily accessible online and in most electronics stores. [23] In addition, home automation devices are increasingly interfaced with mobile phones through Bluetooth, allowing for increased affordability and customizability for the user. [8]
Most wireless-capable residential devices operate at a frequency of 2.4 GHz under 802.11b and 802.11g or 5 GHz under 802.11a. Some home networking devices operate in both radio-band signals and fall within the 802.11n or 802.11ac standards. Wi-Fi is a marketing and compliance certification for IEEE 802.11 technologies. [2]
Matter is a freely available connectivity standard for smart home and IoT (Internet of Things) devices. [2] [3] [4] It aims to improve interoperability and compatibility between different manufacturers and security, and always allowing local control as an option.
