Arduino MKR Relay Proto Shield TSX00003

The Arduino MKR Relay Proto Shield extends the capabilities of your Arduino MKR board by providing two dedicated relays for controlling external loads. This shield is engineered for effortless integration, allowing developers to easily command devices such as lights, motors, or solenoids directly from their MKR-based projects. Each relay is independently controlled via digital pins 1 and 2 of the host board, offering reliable switching for various applications.

Beyond its primary relay function, the shield incorporates a practical prototyping area, offering space to solder additional components, sensors, or custom circuits. This flexibility makes it an ideal platform for developing bespoke IoT devices, home automation systems, and industrial control solutions. The shield also features convenient screw terminal blocks for secure connections to analog inputs (A1-A4), I2C communication (SCL/SDA), and power rails (GND, 3.3V output), simplifying wiring and enhancing project reliability.

Operating at a low 3.3V, supplied directly from the MKR board, this shield is well-suited for power-sensitive applications and projects utilizing battery power. Its robust design, coupled with easy-to-use screw terminals for both relay contacts and general I/O, makes the MKR Relay Proto Shield an essential tool for makers and engineers looking to add switching capabilities and expandability to their Arduino MKR ecosystem.
