ESP32-S3-DEV-KIT-N16R8-M Wi-Fi & BLE Development Board | 240MHz Dual Core, 16MB Flash, 8MB PSRAM, Pre-soldered Headers, Type-C

Overview

The ESP32-S3-DEV-KIT-N16R8-M is a compact, high-performance microcontroller development board built on the Espressif ESP32-S3-WROOM-1-N16R8 module. Powered by an Xtensa 32-bit LX7 dual-core processor running at up to 240 MHz, it comes equipped with 16 MB Flash and 8 MB PSRAM—making it the ideal solution for AIoT applications, complex custom firmware, OTA updates, and high-speed data buffering.

This is the -M variant featuring pre-soldered dual 2×20-pin male headers, allowing you to build and prototype right out of the box with zero soldering required. With onboard CH343 and CH334 chips, the board supports both native USB and USB-to-UART development via a single reversible USB Type-C port, enumerating as two independent serial ports on your host machine.

Designed with a pinout fully compatible with the official Espressif ESP32-S3-DevKitC-1 layout, it offers seamless integration with a vast ecosystem of expansion boards, sensors, and community tutorials across ESP-IDF, Arduino, MicroPython, and PlatformIO.
