ESP32-S3-DevKitM-1

This user guide will help you get started with ESP32-S3-DevKitM-1 and will also provide more in-depth information.

The ESP32-S3-DevKitM-1 is an entry-level development board equipped with either ESP32-S3-MINI-1 or ESP32-S3-MINI-1U, a module named for its small size. This board integrates complete Wi-Fi and Bluetooth Low Energy 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-DevKitM-1 on a breadboard.

Getting Started

This section provides a brief introduction of ESP32-S3-DevKitM-1, instructions on how to do the initial hardware setup and how to flash firmware onto it.

Description of Components

The key components of the board are described in a counter-clockwise direction, starting from the ESP32-S3-MINI-1/1U module.

Key Component

Description

ESP32-S3-MINI-1/1U

ESP32-S3-MINI-1 and ESP32-S3-MINI-1U are two general-purpose Wi-Fi and Bluetooth Low Energy combo modules that have a rich set of peripherals. ESP32-S3-MINI-1 comes with a PCB antenna. ESP32-S3-MINI-1U comes with an external antenna connector. At the core of the modules is ESP32-S3FN8, a chip equipped with an 8 MB flash. Since flash is packaged in the chip, rather than integrated into the module, ESP32-S3-MINI-1/1U has a smaller package size.

5 V to 3.3 V LDO

Power regulator that converts a 5 V supply into a 3.3 V output.

Pin Headers

All available GPIO pins (except for the SPI bus for flash) are broken out to the pin headers on the board for easy interfacing and programming. For details, please seeHeader Block.

USB-to-UART Port

A Micro-USB port used for power supply to the board, for flashing applications to the chip, as well as for communication with the chip via the on-board USB-to-UART bridge.

Boot Button

Download button. Holding downBootand then pressingResetinitiates Firmware Download mode for downloading firmware through the serial port.

Reset Button

Press this button to restart ESP32-S3.

ESP32-S3 USB Port

ESP32-S3 full-speed USB OTG interface, compliant with the USB 1.1 specification. The interface is used for power supply to the board, for flashing applications to the chip, for communication with the chip using USB 1.1 protocols, as well as for JTAG debugging.

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-DevKitM-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.

Hardware Setup

Connect the board with the computer usingUSB-to-UART PortorESP32-S3 USB Port. In subsequent steps,USB-to-UART Portwill be used by default.

Software Setup

Please proceed toGet Started, where SectionInstallationwill quickly help you set up the development environment and then flash an application example onto your board.

Power Supply Options

There are three mutually exclusive ways to provide power to the board:

  • USB-to-UART Port and ESP32-S3 USB Port (either one or both), default power supply (recommended)

  • 5V and G (GND) pins

  • 3V3 and G (GND) pins
