## Description

The ESP32 breakout board brings all 38 pins to screw terminals for quick and secure wiring without soldering. It provides easy access to GPIO, allows for mounting and removing the development board without disconnecting the connections, is compatible with most 38P ESP-32S modules, and is ideal for prototyping, IoT, and automation.
The Breakout Board is a dedicated expansion module for the ESP32 development board, designed to extend the functionality and accessibility of the ESP-32S pins. It allows the redirection of the ESP32 board pins to easily accessible, solderless screw terminals. The ESP board can be easily inserted and removed without the need to disconnect the attached modules.
Compatible with most versions of ESP32 boards, this module is ideal for complex IoT projects, home automation, or prototyping that requires multiple GPIO connections.
IMPORTANT: Check the pin spacing carefully . For example, the ESP32 DEVKIT v1 board has a different pin spacing. Check the picture below for dimensions. Make sure the markings match between the terminal and the ESP32 board.
