Lonely Binary ESP32-S3 N16R8 Gold Edition with Screw Terminal BaseThe Lonely Binary ESP32-S3 N16R8 Gold Edition pairs a powerful dual-core development board with a solderless screw terminal base — built for engineers, hobbyists, and STEM educators. Powered by the dual-core Xtensa LX7 processor (up to 240MHz) with 16MB Flash and 8MB PSRAM for IoT, AI, and embedded applications.
Screw Terminal Base — Secure, Solderless WiringScrew Terminal Connections – Breaks out all GPIOs to screw terminals for secure, vibration-resistant wiring. Ideal for permanent setups, field wiring, and industrial prototypes — no soldering of field wires required.
2.54mm Header Sockets – Built-in female header sockets keep the board breadboard- and jumper-wire compatible alongside the screw terminals.
Top FPC Expansion Connector – Onboard FPC connector for compatible expansion modules and displays (display module sold separately).
Wireless ConnectivityWith 2.4GHz Wi-Fi (802.11 b/g/n) and Bluetooth Low Energy (BLE 5.0), the board supports communication for smart devices, cloud platforms, and connected projects.
Gold Edition DesignBuilt on a black PCB with lead-free immersion gold (ENIG) plating for corrosion resistance and RoHS compliance.
Cross-Platform DevelopmentCompatible with Arduino IDE, MicroPython, and ESP-IDF, supporting macOS, Windows, and Linux. Dual USB Type-C ports handle both power and programming.
