Getting Started
===============
This section provides a brief introduction of ESP32-S2-DevKitC-1, instructions on how to do the initial hardware setup and how to flash firmware onto it.
* - On-board module (ESP32-S2-SOLO or ESP32-S2-SOLO-U in the above figure)
- ESP32-S2-SOLO series modules with an on-board PCB antenna or a connector for an external antenna. This series of modules have multiple options for flash and PSRAM size. For more information, please refer to :ref:`user-guide-s2-devkitc-1-v1-ordering-info`.
- All available GPIO pins (except for the SPI bus for flash) are broken out to the pin headers on the board. For details, please see :ref:`user-guide-s2-devkitc-1-v1-header-blocks`.
* - ESP32-S2 USB Port
- ESP32-S2 full-speed USB OTG interface, compliant with the USB 1.1 specifications. The interface is used for power supply to the board, for flashing applications to the chip, and for communication with the chip using USB 1.1 protocols.
* - Reset Button
- Press this button to restart the system.
* - Boot Button
- Download button. Holding down **Boot** and then pressing **Reset** initiates Firmware Download mode for downloading firmware through the serial port.
- A Micro-USB port used for power supply to the board, for flashing applications to the chip, as well as the communication with the chip via the on-board USB-to-UART bridge.
- Power regulator that converts a 5 V supply into a 3.3 V output.
Start Application Development
-----------------------------
Before powering up your ESP32-S2-DevKitC-1, please make sure that it is in good condition with no obvious signs of damage.
Required Hardware
^^^^^^^^^^^^^^^^^
- ESP32-S2-DevKitC-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.
Connect the board with the computer using **USB-to-UART Port** or **ESP32-S2 USB Port**. In subsequent steps, **USB-to-UART Port** will be used by default.
Please proceed to `ESP-IDF Get Started <https://docs.espressif.com/projects/esp-idf/en/latest/esp32s2/get-started/index.html>`_, where Section `Installation Step by Step <https://docs.espressif.com/projects/esp-idf/en/latest/esp32s2/get-started/index.html#get-started-step-by-step>`_ will quickly help you set up the development environment and then flash an application example into your ESP32-S2-DevKitC-1.
..[#] The ESP32-S2-SOLO-2 and ESP32-S2-SOLO-2U modules use chip revision v1.0, and the rest use chip revision v0.0. For more information about chip revisions, please refer to `ESP32-S2 Series SoC Errata`_.
If you order a few samples, each ESP32-S2-DevKitC-1 comes in an individual package in either antistatic bag or any packaging depending on your retailer.
The two tables below provide the **Name** and **Function** of the pin headers on both sides of the board (J1 and J3). The pin header names are shown in :ref:`user-guide-s2-devkitc-1-v1-board-front`. The numbering is the same as in the `ESP32-S2-DevKitC-1 Schematic`_ (PDF).
