Full-pinout ESP32 board exposing all 38 pins of the ESP32-WROOM-32 — maximum I/O for bigger Wi-Fi and Bluetooth projects.
The 38-pin DevKitC follows Espressif's reference design and breaks out every usable pin of the ESP32-WROOM-32 module, including the extra GPIOs the 30-pin boards hide. It is the best choice when you need many sensors, displays and outputs on one controller, or when following Espressif's official documentation and pinouts.
