This document is intended to help you set up the software development environment for the hardware based on the ESP32-S2 chip by Espressif. After that, a simple example will show you how to use ESP-IDF (Espressif IoT Development Framework) for menu configuration, then for building and flashing firmware onto an ESP32-S2 board.

Note

This is documentation for the master branch (latest version) of ESP-IDF. This version is under continual development. Stable version documentation is available, as well as other ESP-IDF Versions.

ESP32-S2 is a system on a chip that integrates the following features:

Wi-Fi (2.4 GHz band)

High performance single core Xtensa® 32-bit LX7 CPU

Ultra Low Power co-processor running either RISC-V or FSM core

Multiple peripherals

Built-in security hardware

USB OTG interface

Powered by 40 nm technology, ESP32-S2 provides a robust, highly integrated platform, which helps meet the continuous demands for efficient power usage, compact design, security, high performance, and reliability.

Espressif provides basic hardware and software resources to help application developers realize their ideas using the ESP32-S2 series hardware. The software development framework by Espressif is intended for development of Internet-of-Things (IoT) applications with Wi-Fi, Bluetooth, power management and several other system features.

An ESP32-S2 board.

USB cable - USB A / micro USB B.

Computer running Windows, Linux, or macOS.

Note

Currently, some of the development boards are using USB Type C connectors. Be sure you have the correct cable to connect your board!

If you have one of ESP32-S2 official development boards listed below, you can click on the link to learn more about the hardware.

To start using ESP-IDF on ESP32-S2, install the following software:

Toolchain to compile code for ESP32-S2

Build tools - CMake and Ninja to build a full Application for ESP32-S2

ESP-IDF that essentially contains API (software libraries and source code) for ESP32-S2 and scripts to operate the Toolchain

To install all the required software, we offer some different ways to facilitate this task. Choose from one of the available options.

Note

We highly recommend installing the ESP-IDF through your favorite IDE.

Eclipse Plugin

VSCode Extension

For the manual procedure, please select according to your operating system.

If you already have the ESP-IDF installed and not using IDE, you can build your first project from the command line following the Start a Project on Windows or Start a Project on Linux and macOS.
