Designed with convenience in mind, the shield can be powered directly from the 5V line available on most Arduino modules, such as UNO, MEGA, and Leonardo. For 3.3V Arduino modules like ZERO and DUE, an external 5V source can be connected to the screw terminal.

The kit includes everything needed for assembly: a PCB with pre-assembled SMD parts, Nylon spacers, and nuts. Plus, it comes with a downloadable Arduino library and example code to get you started immediately.

Whether you’re creating home automation systems, custom control setups, or educational projects, the CANADUINO 4-Channel Stackable I2C Relay Shield is an essential tool for bringing your innovative ideas to life.
