- Compatibility : Specifically designed for the narrow 38-pin version of the ESP32 without holes. Not compatible with other versions, ensuring a perfect fit for your project. - Connection Options : Features two types of connections: pin header and screw terminal. Choose the one that best suits your project's needs for flexibility and convenience. - GPIO Expansion : This breakout board converts a single GPIO pin from your ESP32 development board into two, allowing for easy reuse of all pins in smart home applications. It serves as an excellent alternative to traditional breadboards. - Dual-Layer PCB : Constructed with a dual-layer printed circuit board, this expansion card offers enhanced stability and reliability. Each pin is wired on both sides, minimizing the risk of poor connections and ensuring stable signal transmission. Use Cases : 1. Smart Home Projects : Easily connect multiple sensors or devices using a single GPIO pin, optimizing your ESP32's capabilities. 2. Prototyping : Simplify your development process by using this breakout board instead of a breadboard, streamlining connections for faster testing and iteration. 3. Educational Use : Ideal for teaching electronics and programming, providing a reliable solution for students to experiment with GPIO connections without the hassle of breadboards. This breakout board is an essential tool for any ESP32 user looking to maximize their development potential while ensuring a reliable and efficient connection.
