This ESP32 breakout board is designed to simplify circuit testing and smart home DIY projects by expanding each GPIO pin into two accessible connections. Built as a reliable alternative to breadboards, this expansion board allows full reuse of ESP32 GPIO pins while ensuring stable electrical connections and clean signal transmission. The board supports both pin headers and screw terminals, offering flexible wiring options for prototyping, testing, and permanent installations.

Key Features

• GPIO 1-to-2 Expansion: Each ESP32 GPIO pin is duplicated into two outputs, enabling easier reuse of pins in complex projects.
• Double-Layer PCB Design: Pins are wired on both sides of the board for enhanced stability, reliability, and reduced signal loss.
• Breadboard Alternative: Provides a cleaner, more secure solution compared to traditional breadboards.
• Flexible Connections: Supports both pin headers and screw terminals (selectable option) for easy and secure wiring.
• DIY Friendly: Ideal for smart home systems, IoT prototypes, testing, and educational projects.
