Using an ESP32-S3 with MicroPython

Instructions to make an ESP32-S3 work with MicroPython. This video describes the steps to control an LED using MicroPython REPL command line. Currently this process requires using a Linux shell, and is shown here using the Terminal app on macOS. Using the Ubuntu shell on Windows also works. Command can be found at the bottom of the description.

Unfortunately, at time this video was made (Dec 2021), there is no support for this board on Arduino.

I bought my board at adafruit
