ESP32 S3 Dev Board - 16MB Flash, 8MB PSRAM - External Antenna

The ESP32-S3 development board features Espressif’s original ESP32-S3-WROOM-1 module with 16MB Flash and 8MB PSRAM (ESP32-S3-WROOM-1-N16R8). It is a general-purpose Wi-Fi + Bluetooth® LE MCU module that integrates full Wi-Fi and Bluetooth LE functionality, making it ideal for IoT, embedded, and edge applications.



Most I/O pins are broken out to headers on both sides of the board for easy interfacing with peripherals. The ESP32-S3 is powered by a dual-core Xtensa LX7 MCU running at 240 MHz, with 512 KB internal SRAM, and supports high-speed SPI Flash and PSRAM with configurable data and instruction caches.

The board also features an RGB WS2812 LED connected to IO38/48 (Red, Green, Blue channels individually addressable), two USB Type-C connectors for power, flashing, and communication, plus full USB OTG support for debugging and JTAG.
