ESP32-S3-DevKitC-1 (N16R8) Development Board – WiFi + BLE | Unwelded Headers, Antenna Support

A powerful and versatile ESP32-S3-DevKitC-1 development board featuring advanced WiFi and Bluetooth Low Energy (BLE) connectivity. Built on the ESP32-S3 dual-core processor, this board is designed for high-performance IoT, AI, and embedded applications.

This variant comes with N16R8 configuration (16MB Flash + 8MB PSRAM), providing ample memory for complex applications such as image processing, machine learning, and large firmware projects.

Unwelded (unsoldered) headers give you full flexibility for custom soldering and integration into your own hardware designs.

Key features

• ESP32-S3 dual-core processor for high performance
• WiFi (2.4GHz) + Bluetooth 5 BLE
• 16MB Flash + 8MB PSRAM (N16R8)
• Antenna support (onboard + external option)
• USB interface for programming and power
• Unwelded headers for flexible assembly
• Rich set of GPIO, ADC, SPI, I²C, UART interfaces

What does N16R8 mean?
