The ESP32-S3-DevKitC-1 is an entry-level development
board equipped with ESP32-S3-WROOM-1, a general-purpose Wi-Fi +
Bluetooth LE MCU module that integrates complete Wi-Fi and Bluetooth LE
functions. This version is equipped with the ESP32-S3-WROOM-1 (PCB
antenna) with 8MB Flash and 8 MB PSRAM.
Please note: The S3 is
similar to the ESP32-S2 - but adds a dual core and Bluetooth LE (not
classic!) However, there is minimal support for this dev board. For
example, as of the time of this writing, there is no Arduino or
CircuitPython support - only ESP IDF! Please purchase if you're doing
development with the S3, and OK with stuff not working 100% out of the
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. We particularly like that there's a
debug UART/USB port and a separate native USB port, so you can
upload/debug/USB all at once.
At the core of the modules is an
ESP32-S3 series of SoC, an Xtensa® 32-bit LX7 CPU that operates at up to
240 MHz. You can power off the CPU and make use of the low-power
co-processor to constantly monitor the peripherals for changes or
crossing of thresholds. ESP32-S3 integrates a rich set of peripherals
including SPI, LCD, Camera interface, UART, I2C, I2S, remote control,
pulse counter, LED PWM, USB Serial/JTAG controller, MCPWM, SDIO host,
GDMA, TWAI® controller (compatible with ISO 11898-1), ADC, touch sensor,
temperature sensor, timers, and watchdogs, as well as up to 45 GPIOs.
It also includes a full-speed USB 1.1 On-The-Go (OTG) interface to
enable USB communication
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
ESP32-S3-WROOM-1: ESP32-S3-WROOM-1 is a powerful, generic Wi-Fi +
Bluetooth LE MCU module that has a rich set of peripherals. It provides
acceleration for neural network computing and signal processing
workloads. ESP32-S3-WROOM-1 comes with a PCB antenna.
5V to 3.3V LDO: Power regulator that converts a 5V supply into a 3.3V 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
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.
Native 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
Boot Button: Download button. Holding down Boot and
then pressing Reset initiates Firmware Download mode for downloading
firmware through the serial port.
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.
3.3V Power On LED: Turns on when the USB power is connected to the board.
