Terminal Block Shield for Arduino Mega

The Terminal Block Shield for Arduino Mega provides secure screw terminal connections to prevent loose wiring and signal drops in your circuits. Ideal for students, makers, and engineers developing robust prototypes or permanent installations, it breaks out Mega pins alongside convenient power rails.

Secure screw terminal wiring

Screw terminals firmly clamp connected wires to eliminate intermittent faults and loose joints in your setup. Multiple dedicated 3.3V, 5V, and GND ports simplify power distribution across your sensors and actuators.

Wide voltage power input

The board accepts a wide 7V to 24V DC input with a maximum load power of 10W, eliminating the requirement for an external step-down circuit.

Built for permanent installations

The sturdy terminal layout keeps wiring tidy and resilient, making it suitable for art installations, commercial projects, and long-term automation tasks.

Onboard 18-pin FPC display socket

An integrated 18-pin FPC port brings out SPI, I2C, touch select, SD card select, and display control pins directly from the Mega for quick screen attachment.

Hardware specifications

The shield measures 101.5 mm by 53.3 mm and uses 3.5 mm pitch terminal blocks with M2 screws, supporting wire gauges from 26 AWG to 16 AWG with a 5 mm strip length.
