This user guide provides information on ESP32-S2-Saola-1, a small-sized ESP32-S2 based development board produced by Espressif.
The document consists of the following major sections:
- Getting started: Provides an overview of the ESP32-S2-Saola-1 and hardware/software setup instructions to get started.
- Hardware reference: Provides more detailed information about the ESP32-S2-Saola-1's hardware.
- Related Documents: Gives links to related documentation.
This section describes how to get started with ESP32-S2-Saola-1. It begins with a few introductory sections about the ESP32-S2-Saola-1, then Section Start Application Development provides instructions on how to get the ESP32-S2-Saola-1 ready and flash firmware into it.
ESP32-S2-Saola-1 is a small-sized ESP32-S2 based development board produced by Espressif. Most of the I/O pins are broken out to the pin headers on both sides for easy interfacing. Developers can either connect peripherals with jumper wires or mount ESP32-S2-Saola-1 on a breadboard.
To cover a wide range of users' needs, ESP32-S2-Saola-1 supports:
In this guide, we take ESP32-S2-Saola-1 equipped with ESP32-S2-WROVER as an example.
If you order a few samples, each ESP32-S2-Saola-1 comes in an individual package in either antistatic bag or any packaging depending on your retailer.

| Key Component | Description |
|---|---|
| ESP32-S2-WROVER | ESP32-S2-WROVER is a powerful, generic Wi-Fi MCU module that integrates ESP32-S2. It has a PCB antenna, a 4 MB external SPI flash and an additional 2 MB PSRAM. |
| I/O Connector | All available GPIO pins (except for the SPI bus for flash and PSRAM) are broken out to the pin headers on the board. Users can program ESP32-S2 chip to enable multiple functions such as SPI, I2S, UART, I2C, touch sensors, PWM etc. |
| USB to UART Bridge | Single USB-UART bridge chip provides transfer rates up to 3 Mbps. |
| Boot Button | Download button. Holding down Boot and then pressing Reset initiates Firmware Download mode for downloading firmware through the serial port. |
| Reset Button | Reset button. |
| 3.3 V Power On LED | Turns on when the USB power is connected to the board. |
| Micro-USB Port | USB interface. Power supply for the board as well as the communication interface between a computer and the ESP32-S2 chip. |
| RGB LED | Addressable RGB LED (WS2812), driven by GPIO18. |
Before powering up your ESP32-S2-Saola-1, please make sure that it is in good condition with no obvious signs of damage.
- ESP32-S2-Saola-1
- USB 2.0 cable (Standard-A to Micro-B)
- Computer running Windows, Linux, or macOS
Please proceed to ../../get-started/index, where Section get-started-step-by-step will quickly help you set up the development environment and then flash an application example into your ESP32-S2-Saola-1.
Note
ESP32-S2 only supports ESP-IDF master or version v4.2 and higher.
