The Grove – Relay v1.2 is the most awaited product for those who want a device capable of switching much higher currents than normal Arduino boards. The Grove – Relay module is a digital normally-open switch that controls a relay. Using this module, you can control the circuit of high voltage with low voltage, say 5 V on a micro-controller.

The Grove – Relay comes with an LED on the board, which lights up when the controlled terminals get closed and the relay is set to HIGH. The relay will then close allowing the current to flow. In this way, users get notified by LED, so they can understand the status of the relay quickly.  The peak voltage capability of the Grove – Relay is 250 V at 10 A.

Seeed Studio has released the Seeed Relay Selection Guide to choose the relay that best suits your needs. Please exercise great care when working with mains voltages – if in doubt, contact professional persons such as a licensed electrician for help. For all Grove users (especially beginners), Seeed Studio provides guidance PDF documents too. Please download and read through Preface – Getting Started and Introduction to Grove before using the product. This is a suitable product for not only Grove users but also all electronic enthusiasts. So, why wait? Buy now!
