The Arduino UNO R4 WiFi is a 32-bit development board based on the high performance Renesas RA4M1 (Arm Cortex®-M4). It has 14 digital input/output pins (of which 6 can be used as PWM outputs), 6 analog inputs, a clock speed of 48 MHz, a USB-C® connection, as well as pins featuring SPI, I2C and one CAN bus.
3+
The MCU on the board is the high performance Renesas RA4M1 (Arm Cortex®-M4) with a 48 MHz clock speed, 32 kB SRAM and 256 kB flash memory. This MCU features an RTC, a DAC and a CAN bus and has support for HID via USB.

The UNO is the most used and documented board of the whole Arduino family, and in this flavour the UNO can do more than ever.
8+
The Arduino UNO R4 WiFi is designed around the 32-bit microcontroller RA4M1 from [Renesas](https://www.renesas.com/us/en) while also featuring a ESP32 module for Wi-Fi® and Bluetooth® connectivity. Its distinctive 12x8 LED matrix makes it possible to prototype visuals directly on the board, and with a QWIIC connector, you can create projects plug-and-play style.
