Lonely Binary ESP32-S3 N16R8 Gold Edition Development Board with 2.54mm Expansion Board

The Lonely Binary ESP32-S3 N16R8 Gold Edition Development Board is built for engineers, hobbyists, and STEM educators. Powered by the dual-core Xtensa LX7 processor (up to 240 MHz), it integrates 16MB Flash and 8MB PSRAM for IoT, AI, and embedded applications.

Wireless Connectivity

With WiFi 2.4GHz (802.11 b/g/n) and Bluetooth 5.0 LE, the board supports communication for smart devices, cloud platforms, and connected projects.

2.54mm Expansion Board

The included 2.54mm expansion board provides male and female pin headers for all GPIOs, compatible with jumper wires and breadboards for flexible prototyping and sensor integration.

Power Input

The board accepts 5V via the USB Type-C ports (for power and programming) or 5–12V via the VIN pin. Apply higher voltages only to the VIN pin — do not exceed 5V on the USB-C ports.

Gold Edition Design

Built on a black PCB with lead-free immersion gold (ENIG) plating for corrosion resistance and RoHS compliance.

Cross-Platform Development

Compatible with Arduino IDE, MicroPython, and ESP-IDF, supporting macOS, Windows, and Linux. Dual USB Type-C ports handle both power and programming.

Compact Form Factor

Measuring 50mm × 40mm, the ESP32-S3 N16R8 board suits STEM education, IoT devices, and embedded AI projects.
