Arduino no longer produces this board. Unfortunately, the more popular boards like the Uno, classic Nano, and Mega 2560 don't support the Debugger feature as they're powered by an AVR microcontroller.

But Arduino would like to create a system where anyone can move blocks of IP around with a tool that’s easy for beginners. A Facelift for the Uno WiFi First up is the brand new Arduino Uno WiFi.

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.

The Arduino Nano and Uno are equipped with very similar processors (the chip that essentially serves as the brain of the board). The Nano features an ATmega328, while the Uno sports an ATmega328P.

The Arduino Zero uses an Atmel ARM Cortex-M0+ for 256kB of Flash and 32k of RAM. The board supports Atmel’s Embedded Debugger, finally giving the smaller Arduino boards debugging support.

Arduino, the world's leading open-source hardware and software platform, today announced the launch of its next-generation UNO board, a significant re ...

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 ...

Having trawled though Arduino's just-released Uno R4 literature, here are the Uno R4 WiFi and R4 Minima in a nutshell: Features common to Arduino R4 - ...

The UNO R4 WiFi features Wi-Fi and Bluetooth Low Energy connectivity, while the UNO R4 Minima provides a cost-effective option for those seeking the new microcontroller without additional features.

Arduino collaborated closely with partners Renesas and Espressif to create the ‘most compatible and powerful maker board on the market’.
