Lonely Binary ESP32-S3 N16R8 Gold Edition with Screw Terminal Base

TheLonely Binary ESP32-S3 N16R8 Gold Editionpairs a powerful dual-core development board with a solderlessscrew terminal base built for engineers, hobbyists, and STEM educators. Powered by the dual-core Xtensa LX7 processor (up to 240MHz) with16MB Flashand8MB PSRAMfor IoT, AI, and embedded applications.

Screw Terminal Base Secure, Solderless Wiring

• Screw 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).
• Mounting-Hole Compatibility Base mounting holes align with common building-block systems for enclosure and rig building.

Wireless Connectivity

With2.4GHz Wi-Fi (802.11 b/g/n)andBluetooth Low Energy (BLE 5.0), the board supports communication for smart devices, cloud platforms, and connected projects.

Gold Edition Design

Built on a black PCB withlead-free immersion gold (ENIG) platingfor corrosion resistance and RoHS compliance.

Cross-Platform Development

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