Introduction
The ESP32-S3-DevKitC-1 is an entry-level development board featuring the ESP32-S3-WROOM-1 module. The module contains a Xtensa® dual-core 32-bit LX7 microprocessor running up to 240 MHz with AI acceleration capabilities, 512 KB SRAM, and 4 MB SPI flash. The board supports both Wi-Fi and Bluetooth 5 (LE). It breaks out most I/O pins to headers on both sides for easy use with breadboards. It includes a USB-to-UART bridge (Micro-USB) for power and programming, and a native ESP32-S3 USB OTG port. An addressable RGB LED is connected to GPIO48.
ESP32-S3-WROOM-1 is a powerful, generic Wi-Fi+ Bluetooth LE MCU module built around the ESP32-S3 series of SoCs. On top of a rich set of peripherals, the acceleration for neural network computing and signal processing workloads provided by the SoC makes the module an ideal choice for a wide variety of application scenarios related to Artificial Intelligence of Things (AIoT), such as wake word detection, speech commands recognition, face detection, and recognition, smart home, smart appliances, smart control panel, smart speaker, etc.
Description of Components
| Key Component | Description |
| ESP32-S3-WROOM-1/1U/2 | ESP32-S3-WROOM-1 are powerful, generic Wi-Fi + Bluetooth LE MCU modules that have a rich set of 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. |
| 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. |
| 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 the system. |
| 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. |
