The Arduino UNO R4 Minima and the Arduino UNO R4 WiFi. But apart from the obvious wireless connectivity hinted by the name what other differences do the microcontrollers have.

Arduino Uno R4 WiFi comes with built-in Wi-Fi and Bluetooth capabilities, along with additional pins and a new, faster processor.

Wi-Fi version with Espressif module The R4 WiFi version comes with an Espressif ESP32-S3 module for Wi-Fi and Bluetooth Low Energy connectivity. The bright 12x8 red LED matrix is ideal for creative ...

RS Components has announced the availability of the latest Arduino board that comes with WiFi wireless networking capability and more processing power than previously available. This has been achieved ...

Arduino has launched its next generation of UNO boards, introducing a 32-bit Renesas microcontroller and Espressif ESP32-S3 module, one-click cloud connectivity and plenty of I/O plus a 12×8 red LED ...

Features common to Arduino R4 – ‘WiFi’ (€25, below) and ‘Minima’ (€18, right) IO connections are in physically similar positions to Uno R3, and IO remains 5V.

The devboards have headers for the ESP8266, an on-board ATmega328 for Arduino Uno compatibility, and a USB to serial converter to make interfacing easy.

Someone has invented a way to add Wi-Fi to a standard Arduino Uno, by proposing a module that drops into the DIL socket normally reserved for the ATmega328 – it will not work with Unos that have a ...

The Arduino Uno WiFi and the Arduino/Genuino MKR1000 boards have also tried to capitalize on this niche by tacking a microcontroller onto a WiFi module.

The most advanced projects can be found in the Master kit, which is based on the ESP32 microcontroller. The ESP32 provides a WiFi and a Bluetooth chip and is clocked faster than the Arduino.
