ESP32-S3-DevKitC-1

ESP32-S3-DevKitC-1
  • ESP32-S3 general-purpose development board
  • It has all the ESP32-S3 pins exposed and is easy to connect and use

The ESP32-S3-DevKitC-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-DevKitC-1 on a breadboard.

ESP32-S3-MINI-1/1U

ESP32-S3-MINI-1 and ESP32-S3-MINI-1U are two general-purpose Wi-Fi and Bluetooth LE 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 see Header 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 down Boot and then pressing Reset initiates 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.
