ESP32-S3-DevKitC-1
This user guide will help you get started with ESP32-S3-DevKitC-1 and will also provide more in-depth
information.
The ESP32-S3-DevKitC-1 is an entry-level development board equipped with either ESP32-S3-WROOM-
1 or ESP32-S3-WROOM-1U, a general-purpose Wi-Fi + Bluetooth LE MCU module that integrates
complete Wi-Fi and Bluetooth LE functions.
Most of the I/O pins on the module are broken out to the pin headers on both sides of this board for easy
interfacing. Developers can either connect peripherals with jumper wires or mount ESP32-S3-DevKitC-1
on a breadboard.

Hardware Reference: More detailed information about the board’s hardware. Hardware Revision Details: Revision history, known issues, and links to user guides for previous versions (if any) of the board. Getting Started This section provides a brief introduction of ESP32-S3-DevKitC-1, instructions on how to do the initial hardware setup and how to flash firmware onto it. Description of Components ESP32-S3-DevKitC-1 - front The key components of the board are described in a counter-clockwise direction. Key Component Description ESP32-S3-WROOM-1 and ESP32-S3-WROOM-1U are two powerful, generic Wi-Fi + Bluetooth LE MCU modules that have a rich set of ESP32-S3-WROOM-1/1U peripherals. They provide acceleration for neural network computing and signal processing workloads. 5 V to 3.3 V LDO Power regulator that converts a 5 V supply into a 3.3 V output. All available GPIO pins (except for the SPI bus for flash) are broken Pin Headers out to the pin headers on the board for easy interfacing and programming. For details, please see Header Block.
- Page 3 Key Component Description A Micro-USB port used for power supply to the board, as well as the USB-to-UART Port communication with the ESP32-S3 chip via the on-board USB-to- UART bridge. Download button. Holding down Boot and then pressing Reset Boot Button initiates Firmware Download mode for downloading firmware through the serial port. Reset Button Press this button to restart the system. ESP32-S3 full-speed USB OTG interface, compliant with the USB 1.1 ESP32-S3 USB Port specification. USB-to-UART Bridge Single USB-to-UART bridge chip provides transfer rates up to 3 Mbps. RGB LED Addressable RGB LED, driven by GPIO48. 3.3 V Power On LED Turns on when the USB power is connected to the board. Start Application Development Before powering up your board, please make sure that it is in good condition with no obvious signs of damage. Required Hardware ESP32-S3-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. Software Setup Please proceed to Get Started, where Section Installation Step by Step will quickly help you set up the development environment and then flash an application example onto your board.
