If you ever DON'T see a serial port, or something is not working out with upload you

can always manually enter bootloader mode:

Reset board into ROM bootloader with DFU/BOOT0 + Reset buttons

Select the ESP32S2/S3 Dev Board ROM bootloader serial port in Tools->Port

Upload sketch

Click reset button to launch code

Arduino Blink

The first and most basic program you can upload to your Arduino is the classic Blink

sketch. This takes something on the board and makes it, well, blink! On and off. It's a

great way to make sure everything is working and you're uploading your sketch to the

right board and right configuration.

When all else fails, you can always come back to Blink!

Pre-Flight Check: Get Arduino IDE &

Hardware Set Up

This lesson assumes you have Arduino IDE set up. This is a generalized checklist,

some elements may not apply to your hardware. If you haven't yet, check the previous

steps in the guide to make sure you:

Install the very latest Arduino IDE for Desktop (not all boards are supported by

the Web IDE so we don't recommend it).
