ESP32 38-Pin GPIO Expansion Breakout Board

Description

The ESP32 38-Pin GPIO Expansion Breakout Board is a convenient adapter designed for narrow-version ESP-WROOM-32 / ESP32 development boards. It expands each ESP32 pin into two accessible connection points, making it easier to connect multiple sensors, modules, displays, relays, and other peripherals without complicated wiring. The board features female headers for mounting a compatible 38-pin ESP32 development board and clearly marked GPIO connections for quick identification during prototyping. The expanded pin arrangement provides additional connection points while keeping projects organized and easy to troubleshoot. It is particularly useful for IoT, robotics, automation, educational projects, breadboard prototyping, and permanent installations where several peripherals need to share power, ground, or GPIO connections.
