The Arduino Mega has a LOT of IO pins allowing you to make bigger, more complex projects. Unfortunately, that spaghetti of wiring can quickly get confusing, especially if a pesky loose jumper wire hasn't been noticed. To help avoid these issues, DFRobot has created this terminal block shield for the Arduino Mega, offering well labelled terminal blocks with secure screw connections!
Alongside the IO pins, you'll find multiple 3.3V, 5V, and GND ports, handy for busy projects. It can be powered by 7~24V voltage without an additional buck converter circuit, with an easy to access reset button for your convenience. The onboard 18pin-FPC socket also makes it convenient for connecting a screen.
