The Arduino Modulino® Latch Relay enables energy-efficient control of external electrical loads in automation and smart energy applications. The latching relay uses power only at the moment of switching, making it an excellent choice for battery-powered systems, for example. The module integrates seamlessly into the Modulino® ecosystem and turns complex electronics into simple, interactive projects with minimal code.

The Modulino® Latch Relay is delivered fully assembled and connects via a Qwiic cable to development boards such as the Arduino UNO R4 WiFi, UNO Q, Nano, or Nesso N1 without soldering or complex wiring. Thanks to daisy-chain support, multiple Modulino modules can be chained into a single system. Full compatibility with Arduino software, cloud services, and a large developer community speeds up development for hobbyists, educators, and professionals alike.
