Product Description
The NodeMCU Baseboard Expansion Shield is a game-changing accessory for IoT developers using the NodeMCU V3 (Lolin/Wide) version. Prototyping on a standard breadboard can be frustrating due to the NodeMCU's wide footprint, which often covers all available tie-points. This shield solves that problem by breaking out every pin into organized header sets while providing a dedicated DC Barrel Jack for stable external power. At Robogears, we recommend this baseboard for permanent IoT installations in your Pimpri facility, as it provides a rigid platform that prevents loose jumper wires and handles the high current spikes common during WiFi transmission.
Detailed Key Features
Breadboard-Free Prototyping: Breaks out all NodeMCU pins into easy-to-access headers, allowing you to connect multiple sensors and actuators without cluttering a breadboard.
Versatile Power Input: The onboard DC barrel jack accepts a wide range of voltages (up to 24V), making it compatible with standard 12V power adapters often used in industrial or automotive IoT projects.
Onboard Voltage Regulation: Features high-quality voltage regulators to step down external power to a stable 5V and 3.3V, protecting your ESP8266 module from voltage fluctuations.
GPIO + Power Headers: Each GPIO pin is conveniently grouped with a VCC and GND pin, allowing for direct "plug-and-play" connection of servos and sensors using standard 3-pin jumper cables.
Robust Mechanical Design: Constructed on a high-quality FR4 PCB with four mounting holes, ensuring your IoT project remains secure in its enclosure.
