The Arduino MKR Relay Proto Shield is a specialized expansion board designed for the Arduino MKR series, featuring a relay module and a prototyping area for custom circuit designs. It allows easy integration of high-voltage or high-current devices into your projects, such as motors, lights, or appliances, by using the relay to control their on/off state. The shield also includes a large prototyping area for adding sensors, actuators, and other components, with access to all MKR board I/O pins. Ideal for automation, IoT, and control systems, it provides a seamless solution for building connected, smart devices
