The ESP32 Breakout Board GPIO 1-to-2 is a practical expansion accessory designed for 38-pin ESP32S / ESP32 development boards, allowing each GPIO pin to be split into two accessible outputs. This makes prototyping, testing, and wiring significantly easier when working with multiple peripherals, sensors, or modules.
By breaking out each ESP32 GPIO into duplicated pin headers, this board eliminates the need for jumper wire stacking and reduces connection strain on the ESP32 itself. It is ideal for breadboard-based development, rapid prototyping, and educational use where clean, organised wiring is essential.
The breakout board is fully compatible with ESP32 2.4 GHz dual-core development boards and works seamlessly with the Arduino IDE as well as other ESP32 development environments.
