Product Description
The ESP32 Expansion Board (30-Pin) is a robust breakout adapter designed to make wiring, prototyping, and sensor integration with standard 30-pin ESP32 development boards clean and effortless. Expanding each GPIO pin into dual terminal pins with VCC and GND power rails, this adapter eliminates the tangled mess of jumper wires on crowded breadboards. It also includes an external DC power input jack to supply stable power to power-hungry sensors and actuators.
Essential for building reliable IoT prototypes, automation panels, and sensor test benches, this versatile breakout board combines secure screw or pin connections with robust power distribution.
⚠️ Compatibility Tip: Ensure your ESP32 development board is the standard 30-pin variant with a 25.4mm (1-inch) pin-to-pin width and 15mm row spacing to guarantee a proper fit into the board’s header sockets.
Technical & Architectural Highlights
Dual Pin Breakout: Every GPIO pin on the ESP32 is expanded into multiple connection points along with dedicated 5V/3.3V and GND rails.
External Power Jack: Features a standard DC barrel jack (or screw terminals) to supply external power directly to your sensors and modules without overloading the ESP32 internal regulator.
Secure Header Sockets: Firmly holds your 30-pin ESP32 development board while providing clear pin-name silkscreen labeling.
Compact & Rugged: Designed for easy mounting into custom project enclosures or flat workshop test benches.
