🔧 Product Overview

Simplify your ESP32-S3 prototyping and DIY electronics projects with this 44-pin GPIO Expansion Breakout Board. It provides easy access to every pin on your ESP32-S3 Development Board (WROOM-1 type) — perfect for smart home systems, IoT devices, and custom automation builds.

This board makes it easy to duplicate, extend, and power your ESP32-S3 connections — no soldering required!

⚙️ Key Features

• 🔌 Pin Duplication: Each ESP32-S3 GPIO pin can be extended into two points, allowing you to connect more sensors, modules, and components simultaneously.
• 🧩 Solderless Plug-and-Play: Directly plug your 44-pin ESP32-S3 Development Board into the onboard socket — no soldering or special adapters needed.
• ⚡ External Power Support: Includes a DC2.1 power input port (supports 6.5V–9V DC) for powering high-current modules and ensuring stable operation.
• 💡 Clear Pin Labeling: All GPIO pins are clearly marked, simplifying prototyping and circuit debugging.

🧠 Compatibility
