The ESP32-S3 is a dual-core XTensa LX7 MCU, capable of running at 240 MHz. Apart from its 512 KB of internal SRAM, it also comes with integrated 2.4 GHz, 802.11 b/g/n Wi-Fi and Bluetooth 5 (LE) connectivity that provides long-range support. It has 45 programmable GPIOs and supports a rich set of peripherals. ESP32-S3 supports larger, high-speed octal SPI flash, and PSRAM with configurable data and instruction cache. There is a RGB WS2812 LED connected to IO38. It has a Red, Green and Blue LED that are individually addressable. This module has 2 USB Type C connectors. The one is used to power the board, for flashing applications to the chip, as well as for communication with the chip via the on-board USB-to-UART bridge. It is connected to a UART of the ESP32 chip via a CH340 chip. The second USB connector is connected to the ESP32-S3 full-speed USB OTG interface, compliant with the USB 1.1 specification. It can also be used to power 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.
