Product Description The 30-Pin ESP32 Expansion Board is a versatile breakout dock designed to simplify the prototyping and wiring of your IoT projects. This shield is specifically engineered for the 30-pin version of the ESP32-WROOM-32 development board. It eliminates the mess of tangled jumper wires by breaking out every pin into a professional G-V-S (Ground-Voltage-Signal) format, making it easy to plug in sensors and servos directly. The unique dual-power interface—featuring both Type-C and Micro-USB ports—ensures compatibility with any cable you have on hand, while the dedicated DC barrel jack allows for high-voltage input for more demanding applications.

Key Highlights
Universal Dual USB Ports: Equipped with both Type-C and Micro-USB ports, providing maximum flexibility for power and programming.
Professional G-V-S Headers: Each GPIO is grouped with its own 5V/3.3V and Ground pins, perfect for connecting sensors, servos, and OLED displays without a breadboard.
Stable Power Management: Features a built-in voltage regulator circuit that can handle a wide DC input (up to 16V) and provide a clean 5V/3.3V supply to the ESP32 and peripherals.
Screw Terminal & DC Jack: Includes multiple power input options, including a 5.5mm DC barrel jack for industrial-style power adapters.
Breadboard-Free Design: The board is designed to act as a stable base for your ESP32, protecting the pins and providing a solid platform for permanent installations.

Installation Tip from Robogears This expansion board is strictly for the 30-pin version of the ESP32. Before plugging in your module, count the pins on one side (it should be 15 pins per side). When mounting the ESP32, ensure the USB port of the development board is facing the same direction as the USB ports on the expansion board. If you are using high-torque servos, we recommend powering the expansion board via the DC Barrel Jack rather than USB to ensure there is enough current to prevent the ESP32 from resetting under load.
