Arduino R4 WIFI motherboard keeps failing to compile? Turns out it's this

My Arduino IDE recognizes my Arduino R4 WiFi motherboard but keeps showing compile failure? What’s going on?
I bought an Arduino R4 WIFI motherboard and I followed the normal connection of the wiring, but my Arduino IDE compiler also recognizes my board but the final compilation result shows “No device found on COM14”, during which I ruled out the code and connection problems as I tried the Arduino R3 motherboard and it eventually compiled successfully. I tried a lot of things and eventually realized it was because the compiler I was using was not compatible with the UNO R4 WiFi board.
Solution:

  1. you can use the latest version of the compiler (Arduino IDE 2.3.2)
  2. Upgrade the UNO R4 WIFI motherboard chip.
