-The UNO R4 WiFi has a ESP32-S3 chip, which handles the USB-to-serial communication. The firmware for this chip can normally be upgraded [using Arduino IDE or Arduino Cloud](https://support.arduino.cc/hc/en-us/articles/9670986058780-Update-the-connectivity-module-firmware-on-UNO-R4-WiFi#iot), but if this is not possible the firmware can be restored using **espflash**.
