About this item
  • 5 x AZDelivery 1 Relay 5V KY-019 Module
  • This microcontroller compatible board with 1 relay for max. 50V AC / 5A or 30V DC / 5A. The 1-channel relay module is equipped with transistor and diode to switch higher loads safely, reliably and with little power. Thanks to its compact size, the 1-channel relay can be used in almost any project.
  • The module is also equipped with a generously sized relay to reliably perform many switching operations. Thanks to the practical holes, the module can be safely mounted in housings.
  • The channel of the module is additionally connected to an LED that indicates the switching status of the relay. The KY-019 relay is used to control AC circuits. The relay acts as a switch that responds to a signal. For this reason, it is widely used in IoT projects to control lights and other electronic devices.
  • This product contains an e-book that contains useful information about the beginning of your project, it helps with a quick setup and saves time in the configuration process. We offer a range of application examples, complete installation guides and libraries.

I wrote to Bigamart's customer support and they accompanied the process of reshipping the item until it finally arrived. I felt a genuine effort to solve the problem till it was finally solved.

The package was here in Australia from England in a few days — so quick! Something was missing and they refunded it straight away. Pretty happy with these guys.
