ESP32 Expansion Board Shield (30-Pin)

Product Overview

The ESP32 Expansion Board Shield (30-Pin) is a convenient development base designed for ESP32 DevKit V1 (30-Pin) development boards. It expands every GPIO pin into a 3-pin interface (Signal, VCC, and GND), making it easy to connect sensors, servos, relays, and other modules without messy wiring or breadboards.

With multiple power input options including USB Type-C, Micro USB, and DC Jack, this expansion board is ideal for rapid prototyping, IoT development, robotics, and embedded system projects.
