MEGA2560 Prototype Shield Board — Screw Terminal Block, Double-Sided PCB, Arduino Mega 2560 R3
A full-size prototype expansion shield for the Arduino Mega 2560 R3, featuring screw terminal blocks on all GPIO pins, a double-sided prototyping PCB area, and clearly labelled power rails. Eliminates the need for soldering wires directly to the Arduino by providing secure screw-terminal connections for every digital, analog, and power pin — ideal for permanent project wiring, sensor integration, and industrial control panel prototyping where reliable, removable wire connections are required.

Typical Applications
- Industrial Control Prototyping: Secure screw-terminal wiring for relay modules, solenoid valves, motor drivers, and sensor inputs in industrial control panel prototypes using Arduino Mega 2560
- Multi-Sensor Data Logger: Connect multiple temperature, humidity, pressure, and flow sensors to Mega 2560 analog and digital inputs via screw terminals for permanent data logging installations
- CNC & 3D Printer Control: Prototype custom CNC controller or 3D printer control board using Mega 2560 with screw-terminal stepper driver, endstop, and heater connections
- Home Automation: Permanent wiring for Arduino Mega-based home automation controllers with relay outputs, sensor inputs, and RS-485/Modbus communication
- Educational Projects: Classroom and lab prototyping where students need to connect and disconnect wires repeatedly without soldering
- Custom PCB Prototyping: Use the double-sided prototyping area to build custom sub-circuits (filters, level shifters, signal conditioning) directly on the shield
FAQ
Q: Is this shield compatible with Arduino Mega 2560 clones?
A: Yes. This shield is compatible with any board using the standard Arduino Mega 2560 R3 pinout and form factor, including CH340-based clones.
Q: Can I stack another shield on top of this prototype shield?
A: The screw terminal blocks on the top surface prevent standard shield stacking. This shield is designed as a terminal layer for permanent or semi-permanent wiring rather than a stackable shield.
Q: What wire gauge do the screw terminals accept?
A: The screw terminals accept AWG 28–16 (0.08–1.5mm²) solid or stranded wire. Strip 5–7mm of insulation before inserting.
