The key components of the board are described in a counter-clockwise direction.
| Key Component | Description |
| ESP32-S3-WROOM-1/1U/2 | ESP32-S3-WROOM-1, ESP32-S3-WROOM-1U, and ESP32-S3-WROOM-2 are powerful, generic Wi-Fi + Bluetooth Low Energy MCU modules that have a rich set of peripherals. They provide acceleration for neural network computing and signal processing workloads. ESP32-S3-WROOM-1 and ESP32-S3-WROOM-2 comes with a PCB antenna. ESP32-S3-WROOM-1U comes with an external antenna connector. |
| 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 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. |
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
