Arduino UNO R4 WiFi是一款基于32位Arm® Cortex®-M4 Renesas RA4M1微控制器，具有用于 Wi-Fi®和蓝牙连接的ESP32模块，具备强大的计算能力和多种连接功能。

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.

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 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.

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.

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 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.
