We primarily recommend using the ESP32 chipsets with Arduino. Don't forget you will also need to install the SiLabs CP2104 Driver if you are using an ESP32 board with USB-to-Serial converter! (There's no harm in doing it, so we recommend even if you aren't)

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 CP2104 / CP2102N USB Driver

Many ESP32 boards have a USB-to-Serial converter that talks to the chip itself, and will need a driver on your computer's operating system. The driver is available for Mac, Windows and Linux.

Install CH9102 / CH34X USB Driver

Newer ESP32 boards have a different USB-to-serial converter that talks to the chip itself, and will need a driver on your computer's operating system. The driver is available for Mac and Windows. It is already built into Linux.

If you would like more detail, check out the guide on installing these drivers.

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 cloneing 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 QT Py ESP32-C3 watch out you don't get confused by the other QT Py boards!

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.
