my lesson is stuck on lesson 3 (https://rntlab.com/module-1/installing-the-esp32-board-in-arduino-ide-windows-mac-os-x-and-linux/). I am using Windows 8.1, Arduino 1.8.10, dev board ESP32 Devkit v1. I Has select the board to DOIT ESP32 v1 (on courses is no information about baud rate, but i has try to use 921600 and 115200 but still error). I choose COM port number and i already check at device manager too, com port number is correct.
And then open the WifiScan and upload to board. Here the message error:
Arduino: 1.8.10 (Windows 8.1), Board: "DOIT ESP32 DEVKIT V1, 80MHz, 921600, None" Sketch uses 623662 bytes (47%) of program storage space. Maximum is 1310720 bytes.

What i must do?
Hello Jimmy, can you try this solution by holding the BOOT button in your board while your code is uploading?
It might also be a good idea to try a different USB cable like DK suggested, but I think in your case a capacitor is missing (you can either hold the BOOT button during upload or solder a capacitor).
Let me know your results!
try changing you Cable, not all USB Change are the Same ..
