The Official Arduino Modulino Latch Relay (ABX00138) is a compact, plug-and-play relay module designed for safe and efficient control of external loads in automation and energy-saving applications.
Part of the Modulino ecosystem, it simplifies hardware design by offering a ready-to-use, preassembled solution with minimal coding. Using Qwiic I²C connectivity, the module easily daisy-chains with other Modulino nodes and integrates seamlessly with Arduino boards such as UNO R4 WiFi and Nano.
Its robust design and low-power latching relay make it ideal for edge IoT, smart control, and educational projects.
Features:
- Latching relay for low-power load switching
- Plug-and-play Qwiic (I²C) connectivity
- Seamless integration with Arduino ecosystem
- Compact, preassembled, ready-to-use module
- Daisy-chain support with other Modulino nodes
- Software-configurable I²C address
- Designed for automation and energy efficiency
- Fully supported by Arduino Docs and tools
