Original ESP32-S3-WROOM-1 module from Espressif with

16MB (N16R8) or 8MB (N8R2) Flash and 8MB PSRAM

It is a general-purpose Wi-Fi + Bluetooth® LE MCU module that integrates complete Wi-Fi and Bluetooth LE functions. I/O pins on the module are broken out to the pin headers on both sides of this board for easy interfacing.

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 has integrated 2.4 GHz, 802.11 b/g/n Wi-Fi, and Bluetooth 5 (LE) connectivity, providing long-range support.

ESP32 S3 N16R8 DevKitC-1 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.

Connected to IO38 is an RGB WS2812 LED with Red, Green, and Blue LEDs that are individually addressable. ESP32-S3 is equipped with 2 USB Type C connectors. One is utilized for powering the board, flashing applications to the chip, and facilitating communication via the onboard USB-to-UART bridge.

The ESP32-S3 full-speed USB OTG interface, compliant with the USB 1.1 Specification, is connected to the second USB connector.
