A lot of people have used ESP8266 to add inexpensive WiFi connectivity to their projects, but [Oscar] decided to take it one step further and program an Arduino over WiFi with the ESP8266.

Despite a wealth of tutorials for setting up and writing code for the ESP8266 WiFi module, there has not been much of anything on programming this cheap wireless module with the Arduino IDE ...

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.

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 Arduino Uno WiFi Rev 2 will be available for purchase from the Arduino Store at the end of June, with the MKR Vidor 4000 to come later in 2018. Pricing information was not provided.

Arduino introduces its new module »Uno R4«. It is the successor of the R3 module and contains a Wi-Fi module in the extended version. It is also the first Arduino module with 32-bit microcontroller.

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 ...

Amongst a flurry of announcements at Maker Faire Bay Area, Arduino has introduced an easy-to-use FPGA board and a re-boot of Uno Wi-Fi, using a new ATmega processor.
