Arduino Modulino Latch Relay (ABX00138)

Arduino Modulino® Latch Relay allows energy-efficient control of external electrical loads in automation and smart energy applications. The latching relay consumes power only during switching, making it an excellent choice for battery-operated systems. The module integrates seamlessly into the Modulino® ecosystem, transforming complex electronics into simple, interactive projects with minimal coding.

The Modulino® Latch Relay comes preassembled and connects via a Qwiic cable to Arduino UNO R4 WiFi, UNO Q, Nano, or Nesso N1 boards without soldering or complex wiring. Daisy-chain support allows multiple Modulino modules to be linked together into a single system. Full compatibility with Arduino software, cloud services, and the extensive developer community accelerates development for hobbyists, educators, and professionals alike.
