Getting Started
|
|
===============
|
|
|
|
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.
|
|
|
|
Overview
|
|
--------
|
|
|
|
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:

|
- 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.
|
|
* - Pin Headers
|
|
- 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.
|
|
* - 3.3 V Power On LED
|
|
- Turns on when the USB power is connected to the board.
|
|
* - USB-to-UART Bridge
|
|
- Single USB-UART bridge chip provides transfer rates up to 3 Mbps.
|
|
* - Reset Button
|
|
- Reset button.
|
|
* - Micro-USB Port
|
|
- USB interface. Power supply for the board as well as the communication interface between a computer and the ESP32-S2 chip.
|
|
* - Boot Button
|
|
- Download button. Holding down **Boot** and then pressing **Reset** initiates Firmware Download mode for downloading firmware through the serial port.
|
|
* - RGB LED
|
|
- Addressable RGB LED (WS2812), driven by GPIO18.

Start Application Development
|
|
-----------------------------
|
|
|
|
Before powering up your ESP32-S2-Saola-1, please make sure that it is in good condition with no obvious signs of damage.
|
|
|
|
Required Hardware
|
|
^^^^^^^^^^^^^^^^^
|
|
|
|
- ESP32-S2-Saola-1
|
|
- USB 2.0 cable (Standard-A to Micro-B)
|
|
- Computer running Windows, Linux, or macOS
|
|
|
|
.. note::
|
|
|
|
Be sure to use an appropriate USB cable. Some cables are for charging only and do not provide the needed data lines nor work for programming the boards.
|
|
|
|
Software Setup
|
|
^^^^^^^^^^^^^^
|
|
|
|
Please proceed to :doc:`../../get-started/index`, where Section :ref:`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 series of chips only supports ESP-IDF master or version v4.2 and higher.

Power Supply Options
|
|
^^^^^^^^^^^^^^^^^^^^
|
|
|
|
There are three mutually exclusive ways to provide power to the board:
|
|
|
|
- Micro-USB port, default power supply
|
|
- 5V and GND pin headers
|
|
- 3V3 and GND pin headers
|
|
|
|
It is recommended to use the first option: Micro-USB Port.
|
|
|
|
Header Block
|
|
------------
|
|
|
|
The two tables below provide the **Name** and **Function** of the pin headers on both sides of the board (J2 and J3). The pin header names are shown in :ref:`user-guide-saola-1-v1.2-board-front`. The numbering is the same as in the `ESP32-S2-Saola-1 Schematics`_ (PDF).
