Features:
- Designed specifically for NodeMCU ESP8266 ESP-12E development boards
- Breaks out all GPIO pins into easy-to-use screw terminals
- No soldering required – simplifies wiring and connections
- Clearly labeled pins for quick and error-free setup
- Compatible with sensors, relays, displays, and other modules
- Stable and reliable connections using terminal blocks
- Compact design suitable for prototyping and permanent setups
- Durable FR-4 PCB construction for long-lasting use
Principle of Work:
The terminal adapter works by directly mapping each GPIO pin of the NodeMCU ESP8266 ESP-12E module to a corresponding screw terminal. When the NodeMCU board is inserted into the adapter, all its pins become accessible through these terminals.
Users can connect external wires by tightening them into the screw terminals, creating a firm electrical connection. This eliminates the need for soldering or unstable jumper wire connections. Signals from the NodeMCU, including digital I/O, analog input, and power lines, are routed through the adapter to external devices, enabling easy integration into larger systems.
Pinout:
- Vin: External power input
- 3V3: Regulated 3.3V output
- GND: Ground
- D0–D8: Digital GPIO pins
- A0: Analog input
- RX/TX: UART communication pins
- EN: Enable pin
- RST: Reset pin
Applications:
- IoT prototyping and development with NodeMCU
- Quick connection of sensors, relays, and modules
- Educational electronics and training setups
- Rapid testing and debugging of circuits
- Home automation and smart device projects
- Industrial control and embedded systems
Technical Details:
- Compatible Module: NodeMCU ESP8266 ESP-12E
- PCB Material: FR-4
- PCB Thickness: 1.6 mm
- Board Size: 6.35 x 6.3 x 1 cm
- Connection Type: Screw terminals (GPIO breakout)
Comparisons:
Compared to using a NodeMCU directly on a breadboard, the terminal adapter provides a more secure and organized wiring solution. Breadboards are better suited for temporary prototyping, while this adapter is ideal for semi-permanent or robust connections.
Unlike simple pin headers, the screw terminal design ensures that wires remain firmly connected, reducing the chances of disconnection in more demanding environments.
