This 2-Channel Signal Relay controller is placed on a convenient mini module footprint. It can be controlled by Particle, Arduino, Beaglebone, Onion Omega, ESP8266, etc. making it very versatile. The relays on this controller are rated for low-power signal switching applications, offering an ideal choice for telecommunications, audio, low-power signal, and other resistive or low capacitive load applications. The relays used on this device are Single Pole Double Throw. External devices may be wired to turn on when the relay turns on. Optionally, external devices may be wired to turn off when the relay turns on. This relay should NOT be used in inductive applications (power switching applications involving motors or transformers of any kind).

All I²C Mini Modules are designed to operate at 5VDC. Using a convenient 4-Pin plug, devices can be daisy chained onto the I²C Bus, eliminating the need for soldering. Simply plug together the devices you need for your next automation application.
