ESP32 S3 DevKitC-1 N16R8 WiFi BLE Dev Board

The ESP32-S3-DevKitC-1 N16R8 is a powerful, full-featured development board built around the ESP32-S3-WROOM-1 module, designed for advanced IoT, AI-accelerated, and embedded applications that demand more memory and processing headroom than standard ESP32 boards offer. The “N16R8” designation indicates this variant ships with 16MB of Octal SPI flash memory and 8MB of Octal PSRAM, giving you ample room for complex firmware, machine learning models, and large data buffers.

At its core sits a dual-core Xtensa LX7 processor running at up to 240MHz, supported by 512KB of built-in SRAM and dedicated AI acceleration instructions for running machine learning workloads directly on-device. Integrated 2.4GHz WiFi (802.11 b/g/n) and Bluetooth 5 (LE) with Bluetooth Mesh support provide flexible wireless connectivity options, while Coded PHY and 2Mbps PHY modes extend BLE range and throughput respectively.

The board features dual USB Type-C ports — one dedicated USB-to-UART port via the CH343 chip for programming and serial communication, and a native ESP32-S3 USB OTG port for direct USB device/host functionality. Onboard BOOT and RST buttons simplify firmware flashing, while power, TX, and RX status LEDs provide clear operational feedback. An integrated WS2812 addressable RGB LED gives you an onboard indicator right out of the box. Fully compatible with ESP-IDF, Arduino IDE, and MicroPython, this board is ideal for AIoT projects, edge computing, smart home devices, industrial automation, and human-machine interface development.
