Adafruit ESP32-S3 Manual page 38

Plug your board into your computer, using a known-good data-sync cable, directly, or
via an adapter if needed.
Double-click the reset button (highlighted in red above), and you will see the RGB
status LED(s) turn green (highlighted in green above). If you see red, try another port,
or if you're using an adapter or hub, try without the hub, or different adapter or hub.
For this board, tap reset and wait for the LED to turn purple, and as soon as it turns
purple, tap reset again. The second tap needs to happen while the LED is still purple.
If double-clicking doesn't work the first time, try again. Sometimes it can take a few
tries to get the rhythm right!
A lot of people end up using charge-only USB cables and it is very frustrating! Make
sure you have a USB cable you know is good for data sync.
