Arduino-compatible Sensor Shield V4.0 allows us to build electronics projects just as easily as piling bricks. It can connect to various modules like sensors, servos, relays, buttons, and potentiometers. Just plug & play.
Each functional module has a buckled port with VCC, GND, and Output, which has a corresponding port on the Sensor Shield, connected with a plain 2.54mm dual-female cable you may start playing already.
Buckled brick cables are like cement for bricks, making the connections easier, more secure and more professional looking.
