ESP32-C3-DevKitC-02 is an entry-level development board based on `ESP32-C3-WROOM-02 <https://www.espressif.com/sites/default/files/documentation/esp32-c3-wroom-02_datasheet_en.pdf>`_, a general-purpose module with 4 MB SPI flash. This board integrates complete Wi-Fi and Bluetooth® Low Energy functions.
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-C3-DevKitC-02 on a breadboard.
This section provides a brief introduction of ESP32-C3-DevKitC-02, instructions on how to do the initial hardware setup and how to flash firmware onto it.
- ESP32-C3-WROOM-02 from Espressif is a powerful and general-purpose module that offers Wi-Fi and Bluetooth Low Energy coexistence. It has a PCB antenna and a 4 MB SPI flash.
- 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-c3-devkitc-02-v1-header-blocks`.
* - Boot Button
- Download button. Holding down **Boot** and then pressing **Reset** initiates Firmware Download mode for downloading firmware through the serial port.
* - Micro-USB Port
- USB interface. Power supply for the board as well as the communication interface between a computer and the ESP32-C3 chip.
* - Reset Button
- Press this button to restart the system.
* - USB-to-UART Bridge
- Single USB-to-UART bridge chip provides transfer rates up to 3 Mbps.
* - RGB LED
- Addressable RGB LED, driven by GPIO8.
Start Application Development
-----------------------------
Before powering up your ESP32-C3-DevKitC-02, please make sure that it is in good condition with no obvious signs of damage.
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.
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-C3-DevKitC-02.
If you order a few samples, each ESP32-C3-DevKitC-02 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-c3-devkitc-02-v1-board-front`. The numbering is the same as in the `ESP32-C3-DevKitC-02 Schematic`_ (PDF).
..[2] GPIO2, GPIO8, and GPIO9 are strapping pins of the ESP32-C3 chip. These pins are used to control several chip functions depending on binary voltage values applied to the pins during chip power-up or system reset. For description and application of the strapping pins, please refer to Section Strapping Pins in `ESP32-C3 Datasheet`_.
