ESP32 Expansion Breakout Board

The ESP32 Expansion Breakout Board is a versatile terminal adapter designed for both 30-pin and 38-pin ESP32 development boards, providing professional-grade connectivity solutions for your IoT and embedded projects. This dual-compatibility expansion board breaks out all GPIO pins into convenient screw terminal blocks, enabling secure, solderless connections that are perfect for prototyping, testing, and permanent installations.

Featuring clearly labeled screw terminals for every pin, this board eliminates the hassle of breadboard wiring and provides robust connections that withstand vibration and environmental stress. The high-quality PCB construction ensures excellent signal integrity and long-term reliability. Each GPIO pin is accessible through easy-to-use screw terminals that accept standard wire gauges, making it simple to connect sensors, actuators, displays, relays, and other peripherals.

The compact design includes mounting holes for secure installation in enclosures or on DIN rails. All power rails (3.3V, 5V, GND) are clearly marked and broken out to multiple terminal positions for convenient distribution. The board supports direct insertion of ESP32-WROOM-32 and ESP32-DevKitC modules with either 30-pin or 38-pin configurations.

Ideal for industrial automation, smart home systems, agricultural monitoring, data logging applications, educational projects, and any scenario requiring reliable wire-to-board connections. This expansion board transforms your ESP32 development board into a production-ready platform. Note: This board does NOT include onboard voltage regulation or power supply – power must be supplied through the ESP32 module’s USB connection or external regulated power source.
