Install Arduino IDE

The first thing you will need to do is to download the latest release of the Arduino IDE. You will need to be using version 1.8 or higher for this guide.

Install ESP32 Board Support Package from GitHub

For this board, we recommend you don't use 'release' version of Espressif's board support package because the current release doesn't include board support.

Instead we will install the "very latest" by following these instructions (scroll down for Mac and Linux as well

Basically, install by git clone-ing the Espressif ESP32 board support to get the very latest version of the code.

In the Tools → Board submenu you should see ESP32 Arduino (in sketchbook) and in that dropdown it should contain the ESP32 boards along with all the latest ESP32 boards.

Look for the board called Adafruit pyCamera S3.

The upload speed can be changed: faster speed makes uploads take less time but sometimes can cause upload issues. 921600 should work fine, but if you're having issues, you can drop down lower.
