Arduino MKR Relay Proto Shield with Prototyping Area

The Arduino MKR Relay Proto Shield is a versatile add-on board designed to bring robust relay control to your Arduino MKR projects. It seamlessly stacks onto your MKR board, enabling you to switch higher-power AC or DC circuits directly from your microcontroller's low-voltage signals.

This shield provides two onboard relays, each with screw terminal connections for the common (COM), normally open (NO), and normally closed (NC) contacts. This design ensures secure and effortless wiring for your external devices. The included prototyping area is a significant feature, offering ample space to solder additional components like sensors, buttons, or indicator LEDs, creating a complete, integrated solution on a single board.

Key Features & Specifications

• Dual Relay Control: Independently control two relays for switching separate circuits.
• Prototyping Area: A dedicated space to build and integrate custom circuitry directly onto the shield.
• Secure Connections: Screw terminals provide reliable and tool-free connections for relay outputs.
• Board Power: Operates at 3.3V, drawing power directly from the host Arduino MKR board.
• Electrical Ratings: Capable of carrying currents up to 2A. Maximum switching capacity is 62.50 VA or 30W, with a maximum working voltage of 125V AC or 60V DC and a maximum working current of 1A per relay.

Ideal for automation projects, the MKR Relay Proto Shield is perfect for creating smart home devices, controlling lights, motors, solenoids, or other appliances. Its compact form factor and integrated prototyping make it an excellent choice for developers, students, and hobbyists looking to build reliable and customised switching interfaces.
